| | Updated BGP Operations and Security |
| |
|
The Border Gateway Protocol (BGP) is a critical component in the Internet to exchange routing information between network domains. Due to this central nature, it is important to understand the security and reliability requirements that can and should be ensured to prevent accidental or intentional routing disturbances. Previously, security considerations for BGP have been described in RFC7454 / BCP194. Since the publications of RFC7454 / BCP194, several developments and changes in operational practice took place that warrant an update of these best current practices. This document replaces RFC7454 / BCP194, focusing on the overall goals, and providing a less implementation centric set of best practices. To this end, the document describes the security requirements and goals when operating BGP for exchanging routing information with other networks. The document explicitly does not focus on specific technical implementations and requirements. Operators are advised to consult documentation and contemporary informational documents concerning methods to ensure that these properties are sufficiently ensured in their network. |
| | Extending ICMP for Node Identification |
| |
|
RFC5837 describes a mechanism for Extending ICMP for Interface and Next-Hop Identification, which allows providing additional information in an ICMP error that helps identify interfaces participating in the path. This is especially useful in environments where each interface may not have a unique IP address to respond to, e.g., a traceroute. This document introduces a similar ICMP extension for Node Identification. It allows providing a unique IP address and/or a textual name for the node, in the case where each node may not have a unique IP address (e.g., the IPv6 nexthop deployment case described in draft-chroboczek-intarea-v4-via-v6). |
| | Test Protocol for One-way IP Capacity Measurement |
| |
|
This memo addresses the problem of protocol support for measuring Network Capacity metrics in RFC 9097, where the method deploys a feedback channel from the receiver to control the sender's transmission rate in near-real-time. This memo defines a simple protocol to perform the RFC 9097 (and other) measurements. |

| | Federated TLS Authentication |
| |
|
This document describes the Federated TLS Authentication (FedTLS) protocol, enabling secure machine-to-machine communication within a federation. Both clients and servers perform mutual TLS authentication, establishing trust based on a centrally managed trust anchor published by the federation. Additionally, FedTLS ensures unambiguous identification of entities, as only authorized members within the federation can publish metadata, further mitigating risks associated with unauthorized entities impersonating legitimate participants. This framework promotes seamless and secure interoperability across different trust domains adhering to common policies and standards within the federation. |

| | Certificate Management over CMS (CMC) |
| |
|
This document defines the base syntax for CMC, a Certificate Management protocol using the Cryptographic Message Syntax (CMS). This protocol addresses two immediate needs within the Internet Public Key Infrastructure (PKI) community: |
| | Certificate Management over CMS (CMC): Transport Protocols |
| |
|
This document defines a number of transport mechanisms that are used to move CMC (Certificate Management over CMS (Cryptographic Message Syntax)) messages. The transport mechanisms described in this document are HTTP, file, mail, and TCP. This document obsoletes RFCs 5273 and 6402. |

The ASN.1 structures and the transport mechanisms for the CMC enrollment protocol are covered in other documents. This document provides the information needed to make a compliant version of CMC. This document obsoletes RFCs 5274 and 6402. |
| | IPv6 is Classless |
| |
|
Over the history of IPv6, various classful address models have been proposed, none of which has withstood the test of time. The last remnant of IPv6 classful addressing is a rigid network interface identifier boundary at /64. This document removes the fixed position of that boundary for interface addressing. |
| | Problem Statement with Aggregate Header Limit |
| |
|
This document first updates the concept "Aggregate header limit"(AHL) which is originally proposed in RFC8883 to indicate the total header size that a router is able to process at full forwarding rate. Then this document describes the problems for path calculation and function enablement without the awareness of AHL in IPv6, and the considerations for AHL collection are also included. |
| | Hybrid-Function-Chain (HFC) Framework |
| |
|
With the maturity of cloud native application development, applications can be decomposed into finer grained atomic services. On the other hand, as a distributed computing paradigm, fine grained micro-services could be deployed and implemented in a distributive way among edges to make computing, storage and run-time processing capabilities as close to users as possible to provide satisfied QoE. Under the circumstances analyzed, a Hybrid-Function-Chain (HFC) framework is proposed in this draft, aiming to wisely allocate and schedule resources and services in order to provide consistent end- to-end service provisioning. |
| | Schedule for Segment Routing Policy |

| | Working Group: |
Individual Submissions (none) |
|
This draft proposes a novel mechanism for Source Address Validation (SAV) message propagation based on Segment Routing policies (SR- policy). Traditional SAV mechanisms often rely on routing tables (RIB) and Policy-Based Routing (PBR), but these methods lack the flexibility and granularity needed for some network environments. By leveraging the flexibility and control capabilities of SR-policy, the proposed mechanism ensures that SAV messages are propagated along well-defined paths, ensuring efficient, secure, and accurate source address validation. |

| | Group Address Allocation Protocol (GAAP) |
| |
|
This document describes a design for a lightweight decentralized multicast group address allocation protocol (named GAAP and pronounced "gap" as in "mind the gap"). The protocol requires no configuration setup and no centralized services. The protocol runs among group participants which need a unique group address to send and receive multicast packets. |

| | Update to the ipn URI scheme |
| |
|
This document updates the specification of the ipn URI scheme previously defined in RFC 6260, the IANA registries established in RFC 7116, and the rules for the encoding and decoding of these URIs when used as an Endpoint Identifier (EID) in Bundle Protocol Version 7 (BPv7) as defined in RFC 9171. These updates clarify the structure and behavior of the ipn URI scheme, define new encodings of ipn scheme URIs, and establish the registries necessary to manage this scheme. |
| | The Deprecation HTTP Header Field |
| |
|
The Deprecation HTTP response header field is used to signal to consumers of a resource (in the sense of URI) that the resource will be or has been deprecated. Additionally, the deprecation link relation can be used to link to a resource that provides additional information about planned or existing deprecation, and possibly ways in which client application developers can best manage deprecation. |
| | No-Vary-Search |
| |
|
A proposed HTTP header field for changing how URL search parameters impact caching. |
| | YANG Metadata Annotation for Immutable Flag |
| |
|
This document defines a way to formally document an existing behavior, implemented by servers in production, on the immutability of some system-provided nodes, using a YANG metadata annotation called "immutable" to flag which nodes are immutable. Clients may use "immutable" annotations provided by the server, to know beforehand why certain otherwise valid configuration requests will cause the server to return an error. The immutable flag is descriptive, documenting an existing behavior, not proscriptive, dictating server behaviors. This document updates [RFC6241], [RFC8040], and [RFC8526]. |
| | A YANG Data Model for the Virtual Router Redundancy Protocol (VRRP) |
| |
|
This document describes a YANG data model for the Virtual Router Redundancy Protocol (VRRP). Both versions 2 and 3 of VRRP are covered. The VRRP terminology has been updated conform to inclusive language guidelines for IETF technologies. To avoid YANG non-backward compatible change restrictions, the YANG module will have desigination ietf-vrrp-2.yang rather than ietf-vrrp.yang. This document obsoletes RFC 8347. |

Individual Submissions (none) |
|
This document describes Mastic, a two-party VDAF for the following secure aggregation task: each client holds an input and an associated weight, and the data collector wants to aggregate the weights of all clients whose inputs begin with a prefix chosen by the data collector. This functionality enables two classes of applications. First, it allows grouping metrics by client attributes without revealing which clients have which attributes. Second, it solves the weighted heavy hitters problem, where the goal is to compute the subset of inputs that have the highest total weight. |
| | Private Inexpensive Norm Enforcement (PINE) VDAF |

This document describes PINE, a Verifiable Distributed Aggregation Function (VDAF) for secure aggregation of high-dimensional, real- valued vectors with bounded L2-norm. PINE is intended to facilitate private and robust federated machine learning. |
| | RPKI Repository Problem Statement and Analysis |
| |
|
With the widespread deployment of Route Origin Authorization (ROA) and Route Origin Validation (ROV), Resource Public Key Infrastructure (RPKI) is vital for securing inter-domain routing. RPKI uses cryptographic certificates to verify the authenticity and authorization of IP address and AS number allocations and the certificates are stored in the RPKI Repository. This document conducts the data-driven analysis of the RPKI Repository, including a survey of worldwide AS administrators and a measurement and analysis of the existing RPKI Repository. This document finds that the current RPKI Repository architecture is sensitive to failures and lacks of scalability. An attack or downtime of any repository Publication Point (PP) will prevent RPs from obtaining complete RPKI object views. Furthermore, since the current RPKI Repository is not tamper-resistant, RPKI authorities can easily manipulate RPKI objects without consent from subordinate INR holders. |

| | BGP AS_PATH Verification Based on Autonomous System Provider Authorization (ASPA) Objects |
| |
|
This document describes procedures that make use of Autonomous System Provider Authorization (ASPA) objects in the Resource Public Key Infrastructure (RPKI) to verify the Border Gateway Protocol (BGP) AS_PATH attribute of advertised routes. This type of AS_PATH verification provides detection and mitigation of route leaks and some forms of AS path manipulation. It also provides protection, to some degree, against prefix hijacks with forged-origin or forged- path-segment. |
| | The Resource Public Key Infrastructure (RPKI) to Router Protocol,Version 2 |
| |
|
In order to validate the origin Autonomous Systems (ASes) and Autonomous System relationships behind BGP announcements, routers need a simple but reliable mechanism to receive Resource Public Key Infrastructure (RFC6480) prefix origin data and Router Keys from a trusted cache. This document describes a protocol to deliver them. This document describes version 2 of the RPKI-Router protocol. [RFC6810] describes version 0, and [RFC8210] describes version 1. This document is compatible with both. |

Constrained RESTful Environments (core) |
|
This document defines the security protocol Group Object Security for Constrained RESTful Environments (Group OSCORE), providing end-to-end security of CoAP messages exchanged between members of a group, e.g., sent over IP multicast. In particular, the described protocol defines how OSCORE is used in a group communication setting to provide source authentication for CoAP group requests, sent by a client to multiple servers, and for protection of the corresponding CoAP responses. Group OSCORE also defines a pairwise mode where each member of the group can efficiently derive a symmetric pairwise key with any other member of the group for pairwise OSCORE communication. Group OSCORE can be used between endpoints communicating with CoAP or CoAP-mappable HTTP. |
| | IP Fragmentation Avoidance in DNS over UDP |
| |
|
The widely deployed EDNS0 feature in the DNS enables a DNS receiver to indicate its received UDP message size capacity, which supports the sending of large UDP responses by a DNS server. Large DNS/UDP messages are more likely to be fragmented and IP fragmentation has exposed weaknesses in application protocols. It is possible to avoid IP fragmentation in DNS by limiting the response size where possible, and signaling the need to upgrade from UDP to TCP transport where necessary. This document describes techniques to avoid IP fragmentation in DNS. |

Inter-Domain Routing (idr) |
|
RFC 5492 allows a BGP speaker to advertise its capabilities to its peer. When a route is propagated beyond the immediate peer, it is useful to allow certain characteristics to be conveyed further. In particular, it is useful to advertise forwarding plane features. This specification defines a BGP transitive attribute to carry such information, the "Next Hop Dependent Characteristics Attribute," or NHC. Unlike the capabilities defined by RFC 5492, the characteristics conveyed in the NHC apply solely to the routes advertised by the BGP UPDATE that contains the particular NHC. This specification also defines an NHC characteristic that can be used to advertise the ability to process the MPLS Entropy Label as an egress LSR for all NLRI advertised in the BGP UPDATE. It updates RFC 6790 and RFC 7447 concerning this BGP signaling. |
| | Flexible Hybrid PQ MLS Combiner |
| |
|
This document describes a protocol for combining a traditional MLS session with a post-quantum (PQ) MLS session to achieve flexible and efficient hybrid PQ security that amortizes the computational cost of PQ Key Encapsulation Mechanisms and Digital Signature Algorithms. Specifically, we describe how to use the exporter secret of a PQ MLS session, i.e. an MLS session using a PQ ciphersuite, to seed PQ guarantees into an MLS session using a traditional ciphersuite. By supporting on-demand traditional-only key updates (a.k.a. PARTIAL updates) or hybrid-PQ key updates (a.k.a. FULL updates), we can reduce the bandwidth and computational overhead associated with PQ operations while meeting the requirement of frequent key rotations. |
| | Extending ICMPv6 for SRv6-related Information Validation |

|
This document introduces the mechanism to verify the data plane against the control plane and detect data plane failures in IPv6/SRv6 networks by extending ICMPv6 messages. |
| | Benchmarking Methodology for Source Address Validation |
| |
|
This document defines methodologies for benchmarking the performance of source address validation (SAV) mechanisms. SAV mechanisms are utilized to generate SAV rules to prevent source address spoofing, and have been implemented with many various designs in order to perform SAV in the corresponding scenarios. This document takes the approach of considering a SAV device to be a black box, defining the methodology in a manner that is agnostic to the mechanisms. This document provides a method for measuring the performance of existing and new SAV implementations. |
| | PIM Join/Prune Attributes for LISP Environments using Underlay Multicast |
| |
|
This document specifies an update to the PIM Receiver RLOC Join/Prune attribute that supports the construction of multicast distribution trees where the source and receivers are located in different Locator/ID Separation Protocol (LISP) sites and are connected using underlay IP Multicast. This attribute allows the receiver site to signal the underlay multicast group to the control plane of the root Ingress Tunnel Router (ITR). This document updates RFC 8059. |

| | A Profile of Signed SAVNET-Peering Information (SiSPI) Object for Deploying Inter-domain SAVNET |
| |
|
This document defines a "Signed SAVNET-Peering Information" (SiSPI) object, a Cryptographic Message Syntax (CMS) protected content type included in the Resource Public Key Infrastructure (RPKI). A SiSPI object is a digitally signed object which carries the list of Autonomous Systems (ASes) deploying inter-domain SAVNET. When validated, the eContent of a SiSPI object confirms that the holder of the listed ASN produces the object and the AS has deployed inter- domain SAV and is ready to establish neighbor relationship for preventing source address spoofing. |
| | TOTP Secure Enrollment |

|
This document describes a secure key exchange scheme that extends the Time-Based One-Time Password (TOTP) [RFC6238] de facto enrollment method to prevent compromise of the non-expiring TOTP key by photographic capture of the QR code or by intentional or unintentional persistence of the key string in email, SMS, or other systems outside of the TOTP authenticator system itself. |
| | RTCP Messages for Point Cloud Prioritization |
| |
|
This document specifies RTCP messages and RTP header extensions for exchanging parameters of real-time streamed point clouds. A sender can notify receivers of the currently applied parameters, such as selected regions, and their parameters, such as the respective resolutions and included point attributes. A receiver can request updates to the same parameters using RTCP feedback messages. |
| | Multi-Push-Based Security Event Token (SET) Delivery Using HTTP |
| |
|
This specification defines how multiple Security Event Tokens (SETs) can be delivered to an intended recipient using HTTP POST over TLS. The SETs are transmitted in the body of an HTTP POST request to an endpoint operated by the recipient, and the recipient indicates successful or failed transmission via the HTTP response. |

| | Segment Routing Path MTU in BGP |
| |
|
Segment Routing is a source routing paradigm that explicitly indicates the forwarding path for packets at the ingress node. An SR policy is a set of SR Policy candidate paths consisting of one or more segments with the appropriate SR path attributes. BGP distributes each SR Policy candidate path as combination of an prefix plus a the BGP Tunnel Encapsulation(Tunnel-Encaps) attribute containing an SR Policy Tunnel TLV with information on the SR Policy candidate path as a tunnel. However, the path maximum transmission unit (MTU) information for a segment list for SR path is not currently passed in the BGP Tunnel-Encaps attribute. . This document defines extensions to BGP to distribute path MTU information within SR policies. |

Stateful Hash-Based Signature Schemes (S-HBS) such as LMS, HSS, XMSS and XMSS^MT combine Merkle trees with One-Time Signatures (OTS) to provide signatures that are resistant against attacks using large- scale quantum computers. Unlike conventional stateless digital signature schemes, S-HBS have a state to keep track of which OTS keys have been used, as double-signing with the same OTS key allows forgeries. This document provides guidance and documents security considerations for the operational and technical aspects of deploying systems that rely on S-HBS. Management of the state of the S-HBS, including any handling of redundant key material, is a sensitive topic, and we discuss some approaches to handle the associated challenges. We also describe the challenges that need to be resolved before certain approaches should be considered. |
| | IPv6 Addresses for Ad Hoc Networks |
| |
|
Ad Hoc networks often present a challenging environment for IPv6 addressing due to the undetermined neighborhood properties of their interfaces. IPv6 nodes assign IPv6 addresses to their Ad Hoc networks that must be locally unique. IPv6 nodes must therefore be able to assign topology-independent addresses when topology-oriented IPv6 address delegation services are either absent or only intermittently available. This document introduces a new IPv6 address type that a node can autonomously assign for each of its Ad- Hoc networks. |
| | CATS BGP Extension |
| |
|
CATS (Computing-Aware Traffic Steering) is a traffic engineering approach that takes into account the dynamic nature of computing resources and network state to optimize service-specific traffic forwarding towards a service contact instance. This document defines the control plane BGP extension for CATS (Computing-Aware Traffic Steering). |
| | Stateless MNA-based Egress Protection (SMEP) |
| |
|
The MPLS Network Action (MNA) framework provides a general mechanism for the encoding and processing of network actions and their data. The MPLS Egress Protection Framework specifies a fast reroute framework for protecting IP/MPLS services. To that, end bypass tunnels have to be signaled to the Point of Local Repair (PLR). Further, the PLR must maintain the bypass forwarding state on a per- transport-tunnel basis. This document defines the encoding for the Stateless MNA-based Egress Protection (SMEP) network action. The SMEP network action protects egress routers by providing an alternative MPLS egress label in- stack. SMEP does not require a bypass forwarding state in PLRs. |
| | IGMP and MLD Snooping Yang Module Extension for L2VPN |
| |
|
Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) Snooping could be used in both bridge service and L2VPN service. The old ietf-igmp-mld-snooping yang module just describes the bridge service. In this document we extend the existing ietf-igmp-mld- snooping yang module and make it could be used in L2VPN service. |
| | Terminology and processes for initial security setup of IoT devices |

|
This document provides an overview of terms that are commonly used when discussing the initial security setup of Internet of Things (IoT) devices. This document also presents a brief but illustrative survey of protocols and standards available for initial security setup of IoT devices. For each protocol, we identify the terminology used, the entities involved, the initial assumptions, the processes necessary for completion, and the knowledge imparted to the IoT devices after the setup is complete. |

DCCP communications as defined in RFC 4340 are restricted to a single path per connection, yet multiple paths often exist between peers. The simultaneous use of available multiple paths for a DCCP session could improve resource usage within the network and, thus, improve user experience through higher throughput and improved resilience to network failures. Use cases for Multipath DCCP (MP-DCCP) are mobile devices (e.g., handsets, vehicles) and residential home gateways simultaneously connected to distinct networks as, e.g., a cellular and a Wireless Local Area (WLAN) network or a cellular and a fixed access network. Compared to existing multipath protocols such as MPTCP, MP-DCCP offers special support for latency-sensitive services with different requirements for reliability and in-order delivery. This document specifies a set of extensions to DCCP to support multipath operations. The protocol offers the same type of service to applications as DCCP and provides the components necessary to establish and use multiple DCCP flows across different paths simultaneously. |

| | Key Blinding for Signature Schemes |
| |
|
This document describes extensions to existing digital signature schemes for key blinding. The core property of signing with key blinding is that a blinded public key and all signatures produced using the blinded key pair are independent of the unblinded key pair. Moreover, signatures produced using blinded key pairs are indistinguishable from signatures produced using unblinded key pairs. This functionality has a variety of applications, including Tor onion services and privacy-preserving airdrop for bootstrapping cryptocurrency systems. |
| | The BBS Signature Scheme |
| |
|
This document describes the BBS Signature scheme, a secure, multi- message digital signature protocol, supporting proving knowledge of a signature while selectively disclosing any subset of the signed messages. Concretely, the scheme allows for signing multiple messages whilst producing a single, constant size, digital signature. Additionally, the possessor of a BBS signatures is able to create zero-knowledge, proofs-of-knowledge of a signature, while selectively disclosing subsets of the signed messages. Being zero-knowledge, the BBS proofs do not reveal any information about the undisclosed messages or the signature it self, while at the same time, guarantying the authenticity and integrity of the disclosed messages. |
| | Grant Negotiation and Authorization Protocol Resource Server Connections |
| |

GNAP defines a mechanism for delegating authorization to a piece of software (the client), and conveying the results and artifacts of that delegation to the software. This extension defines methods for resource servers (RS) to connect with authorization servers (AS) in an interoperable fashion. |
| | Use Cases for MPLS Network Action Indicators and MPLS Ancillary Data |
| |
|
This document presents use cases that have a common feature that may be addressed by encoding network action indicators and associated ancillary data within MPLS packets. There is community interest in extending the MPLS data plane to carry such indicators and ancillary data to address the use cases that are described in this document. The use cases described in this document are not an exhaustive set, but rather the ones that are actively discussed by members of the IETF MPLS, PALS, and DetNet working groups from the beginning of work on the MPLS Network Action until the publication of this document. |
| | Arm's Platform Security Architecture (PSA) Attestation Token |
| |
|
The Arm Platform Security Architecture (PSA) is a family of hardware and firmware security specifications, as well as open-source reference implementations, to help device makers and chip manufacturers build best-practice security into products. Devices that are PSA compliant can produce attestation tokens as described in this memo, which are the basis for many different protocols, including secure provisioning and network access control. This document specifies the PSA attestation token structure and semantics. The PSA attestation token is a profile of the Entity Attestation Token (EAT). This specification describes what claims are used in an attestation token generated by PSA compliant systems, how these claims get serialized to the wire, and how they are cryptographically protected. This informational document is published as an independent submission to improve interoperability with Arm's architecture. It is not a standard nor a product of the IETF. |

| | Multiple Hop Unaffiliate BFD |
| |
|
The Bidirectional Forwarding Detection (BFD) is a fault detection protocol designed to rapidly identify communication failure between two forwarding engines. This document suggests utilizing BFD Echo when the local system supports BFD, but the neighboring system does not. BFD Control packets and their processing procedures can be executed over the BFD Echo port, where the neighboring system solely loops packets back to the local system. This document serves as an update to RFC 5880 and draft-ietf-bfd- unaffiliate-echo-10. |

| | Notification of Revoked Access Tokens in the Authentication and Authorization for Constrained Environments (ACE) Framework |
| |
|
This document specifies a method of the Authentication and Authorization for Constrained Environments (ACE) framework, which allows an authorization server to notify clients and resource servers (i.e., registered devices) about revoked access tokens. As specified in this document, the method allows clients and resource servers to access a Token Revocation List on the authorization server by using the Constrained Application Protocol (CoAP), with the possible additional use of resource observation. Resulting (unsolicited) notifications of revoked access tokens complement alternative approaches such as token introspection, while not requiring additional endpoints on clients and resource servers. |

| | Impact of DLTs on Provider Networks |
| |
|
This document discusses the impact of distributed ledger technologies being realized over IP-based provider networks. The focus here lies on the impact that the DLT communication patterns have on efficiency of resource usage in the underlying networks. We provide initial insights into experimental results to quantify this impact in terms of inefficient and wasted communication, aligned along challenges that the DLT realization over IP networks faces. This document intends to outline this impact but also opportunities for network innovations to improve on the identified impact as well as the overall service quality. While this document does not promote specific solutions that capture those opportunities, it invites the wider community working on DLT and network solutions alike to contribute to the insights in this document to aid future research and development into possible solution concepts and technologies. The findings presented here have first been reported within the similarly titled whitepaper released by the Industry IoT Consortium (IIC) [IIC_whitepaper]. |
| | BGP Blockchain |
| |
|
A variety of mechanisms have been developed and deployed over the years to secure BGP including the more recent RPKI/ROA mechanisms. Is it also possible to use a distributed ledger such as Blockchain to secure BGP? BGP provides decentralized connectivity across the Internet. Blockchain provides decentralized secure transactions in a append-only, tamper-resistant ledger. This document reviews possible opportunities of using Blockchain to secure BGP policies within a domain and across the global Internet. We propose that BGP data could be placed in a blockchain and smart contracts can control how the data is managed. This could create a single source of truth, something for which blockchains are particularly well suited. |

Global Token Revocation enables parties such as a security incident management tool or an external Identity Provider to send a request to an Authorization Server to indicate that it should revoke all of the user's existing tokens and require that the user re-authenticates before issuing new tokens. |
| | Title File Size Download Prompt (FSDP) |
| |
|
In the context of limited mobile data plans, it is crucial to manage data usage efficiently. This document proposes a method using the HTTP `OPTIONS` header to retrieve the size of a file before downloading. By checking the `Content-Length` header, users can be informed of the file size and prompted to confirm the download. This approach helps users avoid unexpected data consumption and ensures better control over their mobile data usage. |

| | RTP Payload Format for Visual Volumetric Video-based Coding (V3C) |
| |
|
A visual volumetric video-based coding (V3C) [ISO.IEC.23090-5] bitstream is composed of V3C units that contain V3C atlas sub- bitstreams, V3C video sub-bitstreams, and a V3C parameter set. This memo describes an RTP payload format for V3C atlas sub-bitstreams. The RTP payload format for V3C video sub-bitstreams is defined by relevant Internet Standards for the applicable video codec. The V3C RTP payload format allows for packetization of one or more V3C atlas Network Abstraction Layer (NAL) units in an RTP packet payload as well as fragmentation of a V3C atlas NAL unit into multiple RTP packets. The memo also describes the mechanisms for grouping RTP streams of V3C component sub-bitstreams, providing a complete solution for streaming V3C encoded content. |
| | The Concealed HTTP Authentication Scheme |
| |
|
Most HTTP authentication schemes are probeable in the sense that it is possible for an unauthenticated client to probe whether an origin serves resources that require authentication. It is possible for an origin to hide the fact that it requires authentication by not generating Unauthorized status codes, however that only works with non-cryptographic authentication schemes: cryptographic signatures require a fresh nonce to be signed. Prior to this document, there was no existing way for the origin to share such a nonce without exposing the fact that it serves resources that require authentication. This document defines a new non-probeable cryptographic authentication scheme. |

Mobile peers exchange signals with networks, for both wireline and wireless domains, to negotiate capabilities for mobile registration, connection management, session establishment, service provisioning, etc. Generally, mobility capabilities include the supported and provisioned resources along with associated protocols for certain mobility management scenarios. While devices in the mobile wireline (IP) domain would mostly focus on the IP-related negotiation, devices in the wireless domain, e.g., the 5G system (5GS), embrace both mobile IP-related resources as well as wireless-specific capabilities. Regarding both the mobile-IP and wireless domains, we have generalized two protocol categories for mobility capability negotiation & management, i.e., the host-initiated category that involves the direct & active engagement of mobile end devices vs. the network-based category over which mobile endpoints play almost no role in the process. The classification and then the application of the two categories help us analyze the mobility capability negotiation for both the mobile IPv6 and the 3GPP 5G system. The comparison of the capability negotiation under both the Home-Routed (HR) and the Local BreakOut (LBO) roaming cases in 5GS further reflects the feasibility of the protocol dichotomy. |
| | Compact UUIDs for Constrained Grammars |
| |
|
The Universally Unique Identifier is a suitable standard for, as the name suggests, uniquely identifying entities in a symbol space large enough that the identifiers do not collide. Many formal grammars, however, are too restrictive to permit the use of UUIDs in their canonical representation (described in RFC 4122 and elsewhere), despite it being useful to do so. This document specifies an alternative compact representation for UUIDs that preserves some properties of the canonical form, with three encoding varietals, to fit these more restrictive contexts. |

This document describes the AVORS (Avoiding Registration Storms) concept that allows the resumption of active UE (User Equipment) registrations on other SIP Proxies within the SIP voice architecture. The concept can be mapped on any architecture having a distributed structure and could work for different protocols. In this document, the concept is exemplary explained regarding an architecture for voice and could also be mapped on a 3GPP (3rd Generation Partnership Project) architecture. The AVORS concept increases service continuity, improves network resilience and offers savings potential. Additionally, this document gives an outlook regarding stateless voice architectures, load calculation aspects, and Service Based Interfaces (SBI) with session data base interworking. Security aspects are considered in the security chapter. As stated above the AVORS principle is not only limited to the SIP protocol and could be adopted by other protocols. |

This document proposes extensions to the SMTP, IMAP, POP3, and MIME protocols to introduce a standard mechanism for email retention period management. |
| | Standard API Password Change Interface (SAPI) for Password Change Procedures |
| |
|
This document proposes a standardized set of API endpoints for securely changing user passwords, using a unique identifier prefix to ensure compatibility and avoid conflicts with other APIs. As the number of online accounts continues to grow, managing passwords has become increasingly challenging. Even with the use of password managers, the process of updating passwords-whether due to a security breach, expiration, or other reasons-remains a time-consuming and manual task. Currently, there is no standardized method for performing password changes across various platforms, which further complicates this process. The goal of this proposal is to establish a universal standard for password change processes, enabling password managers and services to automate password updates with minimal configuration, thereby reducing the burden on users and improving overall security. |

BGP Enabled ServiceS (bess) |
|
As Enterprises and Service Providers upgrade their brown field or green field MPLS/SR core to an IPv6 transport, Multiprotocol BGP (MP- BGP)now plays an important role in the transition of their Provider (P) core network as well as Provider Edge (PE) Inter-AS peering network from IPv4 to IPv6. Operators must have flexiblity to continue to support IPv4 customers when both the Core and Edge networks migrate to IPv6. As well as must be able to support IPv6 networks in cases where operators decide to remain on an IPv4 network or during transition. This document details the External BGP (eBGP) PE-PE Inter-AS and PE- CE Edge peering IPv4-Only PE design where both IPv4 and IPv6 all supported SAFI NLRI can be advertised over a single IPv4 peer and IPv6-Only PE Design where all supported SAFI NLRI can be advertised over a single IPv6 peer. This document also defines a new IPv4 BGP next hop encoding standard that uses an IPv4 address as the next hop and not an IPv4 mapped IPv6 address. This document also provides vendor specific test cases for the IPv4-Only peering design and IPv6-Only PE design as well as test results for the four major vendors stakeholders in the routing and switching indusrty, Cisco, Juniper, Nokia and Huawei. With the test results provided for the IPv6-Only Edge peering design, the goal is that all other vendors around the world that have not been tested will begin to adopt and implement the design. |
| | Clarifications on CDS/CDNSKEY and CSYNC Consistency |
| |
|
Maintenance of DNS delegations requires occasional changes of the DS and NS record sets on the parent side of the delegation. For the case of DS records, RFC 7344 provides automation by allowing the child to publish CDS and/or CDNSKEY records holding the prospective DS parameters which the parent can ingest. Similarly, RFC 7477 specifies CSYNC records to indicate a desired update of the delegation's NS (and glue) records. Parent-side entities (e.g. Registries, Registrars) can query these records from the child and, after validation, use them to update the parent-side RRsets of the delegation. This document specifies that when performing such queries, parent- side entities MUST ensure that updates triggered via CDS/CDNSKEY and CSYNC records are consistent across the child's authoritative nameservers, before taking any action based on these records. |
| | DULT Threat Model |
| |
|
Lightweight location tracking tags are in wide use to allow users to locate items. These tags function as a component of a crowdsourced tracking network in which devices belonging to other network users (e.g., phones) report which tags they see and their location, thus allowing the owner of the tag to determine where their tag was most recently seen. While there are many legitimate uses of these tags, they are also susceptible to misuse for the purpose of stalking and abuse. A protocol that allows others to detect unwanted location trackers must incorporate an understanding of the unwanted tracking landscape today. This document provides a threat analysis for this purpose, will define what is in and out of scope for the unwanted location tracking protocols, and will provide some design considerations for implementation of protocols to detect unwanted location tracking. |
| | Nice Email Addresses for SMTPUTF8 |

|
This document specifies rules for email addresses that are flexible enough to express the addresses typically used with SMTPUTF8, while avoiding confusing or risky elements. This is one of a pair of documents: this contains recommendations for what addresses humans should use, such address provisioning sytems can restrain themselves to addresses that email valdidators accept. (This set can also be described in other ways, including "simple to cut-and-paste".) Its companion defines simpler rules, accepts more addresses, and is intended for software like MTAs. NOTE: The term 'nice' is not ideal here, and must be reconsidered or replaced before this is issued as an RFC. "Well-formed" is a candidate. "Nice" will do for now: better to argue about substance than wording. |

Segment Routing (SR) allows for a flexible definition of end-to-end paths by encoding an ordered list of instructions, called "segments". The SR architecture can be implemented over an MPLS data plane as well as an IPv6 data plane. Currently, Path Segment Identifier (PSID) has been defined to identify an SR path in SR-MPLS networks, and is used for various use- cases such as end-to-end SR Path Protection and Performance Measurement (PM) of an SR path. This document defines the PSID to identify an SRv6 path in an IPv6 network. |

Autonomic Networking Integrated Model and Approach (anima) |
|
This document defines enhancements to the Bootstrapping Remote Secure Key Infrastructure (BRSKI) protocol, known as BRSKI-AE (Alternative Enrollment). BRSKI-AE extends BRSKI to support certificate enrollment mechanisms instead of the originally specified use of EST. It supports certificate enrollment protocols, such as CMP, that use authenticated self-contained signed objects for certification messages, allowing for flexibility in network device onboarding scenarios. The enhancements address use cases where the existing enrollment mechanism may not be feasible or optimal, providing a framework for integrating suitable alternative enrollment protocols. This document also updates the BRSKI reference architecture to accommodate these alternative methods, ensuring secure and scalable deployment across a range of network environments. |

| |
|
BGP Link State (BGP-LS) describes a mechanism by which link-state and TE information can be collected from networks and shared with external components using the BGP routing protocol. The centralized controller (PCE/SDN) completes the service path calculation based on the information transmitted by the BGP-LS and delivers the result to the Path Computation Client (PCC) through the PCEP or BGP protocol. This document specifies the extensions to BGP Link State (BGP-LS) to carry maximum transmission unit (MTU) messages of link. The PCE/SDN calculates the Path MTU while completing the service path calculation based on the information transmitted by the BGP-LS. |
| | BGP Route Reflector with Next Hop Self |
| |
|
The procedures in BGP Route Reflection (RR) spec RFC4456 primarily deal with scenarios where the RR is reflecting BGP routes with next hop unchanged. In some deployments like Inter-AS Option C (Section 10, RFC4364), the ABRs may perform RR functionality with nexthop set to self. If adequate precautions are not taken, the RFC4456 procedures can result in traffic forwarding loop in such deployments. This document illustrates one such looping scenario, and specifies approaches to minimize possiblity of traffic forwarding loop in such deployments. An example with Inter-AS Option C (Section 10, RFC4364) deployment is used, where RR with next hop self is used at redundant ABRs when they re-advertise BGP transport family routes between multiple IGP domains. |

Rather than signing messages individually, the MTL mode of operation signs structures called "Merkle tree ladders" that are derived from the messages to be authenticated. Individual messages are then authenticated relative to the ladder using a Merkle tree authentication path and the ladder is authenticated using the public key of the underlying signature scheme. The size and computational cost of the underlying signatures are thereby amortized across multiple messages, reducing the scheme's operational impact. The reduction can be particularly beneficial when MTL mode is applied to a post-quantum signature scheme that has a large signature size or computational cost. As an example, the document shows how to use MTL mode with the Stateless Hash-Based Digital Signature Algorithm (SLH- DSA) specified in the draft FIPS 205. Like other Merkle tree techniques, MTL mode's security is based only on cryptographic hash functions, so the mode is quantum-safe based on the quantum- resistance of its cryptographic hash functions. |

| | Abridged Compression for WebPKI Certificates |
| |
|
This draft defines a new TLS Certificate Compression scheme which uses a shared dictionary of root and intermediate WebPKI certificates. The scheme smooths the transition to post-quantum certificates by eliminating the root and intermediate certificates from the TLS certificate chain without impacting trust negotiation. It also delivers better compression than alternative proposals whilst ensuring fair treatment for both CAs and website operators. It may also be useful in other applications which store certificate chains, e.g. Certificate Transparency logs. |

| | Adaptive Routing Notification |
| |
|
Large-scale supercomputing and AI data centers utilize multipath to implement load balancing and/or improve transport reliability. Adaptive routing (AR), widely used in direct topologies such as dragonfly, is growing popular in commodity data centers to dynamically adjust routing policies based on path congestion and failures. When congestion or failure occurs, the sensing node can not only apply AR locally but also send the congestion/failure information to other nodes in a timely and accurate manner to enforce AR on other nodes, thus avoiding exacerbating congestion on the reported path. This document specifies Adaptive Routing Notification (ARN), a general mechanism to proactively disseminate congestion detection and congestion elimination information for remote nodes to perform re-routing policies. |

| | STI Certificate Transparency |
| |
|
This document describes a framework for the use of the Certificate Transparency (CT) protocol for publicly logging the existence of Secure Telephone Identity (STI) certificates as they are issued or observed. This allows any interested party that is part of the STI eco-system to audit STI certification authority (CA) activity and audit both the issuance of suspect certificates and the certificate logs themselves. The intent is for the establishment of a level of trust in the STI eco-system that depends on the verification of telephone numbers requiring and refusing to honor STI certificates that do not appear in a established log. This effectively establishes the precedent that STI CAs must add all issued certificates to the logs and thus establishes unique association of STI certificates to an authorized provider or assignee of a telephone number resource. The primary role of CT in the STI ecosystem is for verifiable trust in the avoidance of issuance of unauthorized duplicate telephone number level delegate certificates or provider level certificates. This provides a robust auditable mechanism for the detection of unauthorized creation of certificate credentials for illegitimate spoofing of telephone numbers or service provider codes (SPC). |

| | A Framework for Constructing Service Function Chaining Systems Based on Segment Routing |
| |
|
Segment Routing (SR) introduces a versatile methodology for defining end-to-end network paths by encoding sequences of topological sub- paths, known as "segments". This architecture can be deployed over both MPLS and IPv6 data planes, offering a flexible routing solution. Service Function Chaining (SFC) supports the establishment of composite services through an ordered sequence of Service Functions (SFs) that are applied to packets or frames based on initial classification. SFC's implementation can utilize various underlying technologies, including the Network Service Header (NSH) and SR, to facilitate the creation and management of service chains. This document presents a comprehensive control framework for developing SFC architectures using Segment Routing. It explores control plane solutions for the distribution of service function instance routes and service function paths, as well as techniques for directing packets into specific service function chains. The discussion encompasses both theoretical foundations and practical considerations for integrating SR into SFC deployments. |
| | Compressed SID (C-SID) for SRv6 SFC |
| |
|
In SRv6, an SRv6 SID is a 128-bit value. When too many 128-bit SRv6 SIDs are included in an SRH, the introduced overhead will affect the transmission efficiency of payload. In order to address this problem, Compressed SID(C-SID) is proposed. This document defines new behaviors for service segments with REPLACE-C-SID and NEXT-C-SID flavors to enable compressed SRv6 service programming. |
| | Revisiting the Use of the IP Protocol Stack in Deep Space: Assessment and Possible Solutions |
| |
|
Deep space communications involve long delays (e.g., Earth to Mars is 4-20 minutes) and intermittent communications, because of orbital dynamics. Up to now, communications have been done on a layer-2 point to point basis, with sometimes the use of relays, therefore no layer-3 networking was possible. RFC4838 reports an assessment done around 25 years ago concluding that the IP protocol stack was not suitable for deep space networking. This result lead to the definition of a new protocol stack based on a store-and-forward paradigm implemented in the Bundle Protocol(BP). More recently, space agencies are planning to deploy IP networks on celestial bodies, such as Moon or Mars, ground, and vicinity. This document revisits the initial assessment of not using IP and provides solution paths to use the IP protocol stack, from IP forwarding to transport to applications to network management, in deep space communications. |
| | POSIX Draft ACL support for Network File System Version 4,Minor Version 2 |
| |
|
This document describes a potential protocol extension involving the addition of four new attributes to be used by servers to provide support for POSIX ACLs. The term POSIX ACLs refers to the ACL component of the Portable Operating System Interface (POSIX) 1003.1e draft 17 [IEEE] document for which sponsorship was withdrawn in January 1998. Although the draft POSIX standard that describes these ACLs was never ratified, several POSIX-based operating systems, such as Linux, Solaris and FreeBSD include support for them. The NFS Version 4 (NFSv4) ACLs described in [RFC8881] henceforth referred to as NFSv4 ACLs, use a different model and attempts to map between the ACLs of these two models have not been completely successful. In order to adequately support POSIX ACLs, this document proposes four new attributes that may optionally be used by an NFS Version 4, minor version 2 (NFSv4.2) server to support ACLs that conform to the aforementioned POSIX 1003.1e draft 17. |

Segment Routing (SR) architecture leverages the paradigm of source routing. It can be realized in the Multiprotocol Label Switching (MPLS) network without changing the data plane. Bidirectional Forwarding Detection (BFD) is expected to monitor a segment list, representing a specific source-routed SR Policy path between the headend and an endpoint. This document describes using BFD for monitoring individual segment lists of candidate paths of an SR Policy. It documents the use of various BFD modes and features such as BFD Demand mode, Seamless BFD, and BFD Echo function with the BFD Control packet payload in the SR-MPLS domain. Also, this document defines how to use Label Switched Path Ping to bootstrap a BFD session, with optional control of selecting a segment list in the reverse direction of the BFD session. |

Inter-Domain Routing (idr) |
|
Flow-spec is an extension to BGP that allows for the dissemination of traffic flow specification rules. This has many possible applications, but the primary one for many network operators is the distribution of traffic filtering actions for distributed denial of service (DDoS) mitigation. The flow-spec standard [RFC5575] defines a redirect-to-VRF action for policy-based forwarding. This mechanism can be difficult to use, particularly in networks without L3 VPN infrastructure. This draft defines a new redirect-to-IP flow-spec action that provides a simpler method of policy-based forwarding. The details of the action, including the IPv4 or IPv6 target address, are encoded in newly defined BGP extended communities. |

| | IPv6 Voucher-Based Addressing for Neighbor Discovery Address Resolution |
| |
|
Voucher-Based Addressing is an extensible IPv6 address generation and verification methodology for SLAAC-enabled local networks. Individual link-layer identifiers are bound to sets of deterministic output IP addresses. Neighbor Discovery Link Voucher options distributed with Router Advertisement or Redirect messages form a shared consensus between neighbors of the parameters used to auto- generate interface addresses. Cryptographic key derivation functions are used to generate pseudo-random addresses and to intentionally stretch address computation times. Host-selected parameters can be used to derive any number of both stable and ephemeral, privacy- focused addresses for each on-link prefix and at the link-local scope. Neighbors can then verify the link-layer-to-IP bindings during NDP address resolution processes to prevent active neighbor spoofing attacks in local networks. |

|
By and large, a correct operation of a RPL network requires border routers to be up. In many applications, it is beneficial for the nodes to detect a crash of a border router as soon as possible to trigger fallback actions. This document describes RNFD, an extension to RPL that expedites border router failure detection, even by an order of magnitude, by having nodes collaboratively monitor the status of a given border router. The extension introduces an additional state at each node, a new type of RPL Control Message Options for synchronizing this state among different nodes, and the coordination algorithm itself. |

RFC 6951 specifies the UDP encapsulation of SCTP packets. The described handling of received packets requires the check of the verification tag. However, RFC 6951 misses a specification of the handling of received packets for which this check is not possible. This document updates RFC 6951 by specifying the handling of received packets for which the verification tag can not be checked. |
| | UDP Encapsulation of Stream Control Transmission Protocol (SCTP) Packets for End-Host to End-Host Communication |
| |
|
This document describes a simple method of encapsulating Stream Control Transmission Protocol (SCTP) packets into UDP packets and its limitations. This allows the usage of SCTP in networks with legacy NATs that do not support SCTP. It can also be used to implement SCTP on hosts without directly accessing the IP layer, for example, implementing it as part of the application without requiring special privileges. Please note that this document only describes the functionality needed within an SCTP stack to add on UDP encapsulation, providing only those mechanisms for two end-hosts to communicate with each other over UDP ports. In particular, it does not provide mechanisms to determine whether UDP encapsulation is being used by the peer, nor the mechanisms for determining which remote UDP port number can be used. These functions are out of scope for this document. This document covers only end-hosts and not tunneling (egress or ingress) endpoints. It obsoletes RFC 6951. |
| | INIT Forwarding for the Stream Control Transmission Protocol |
| |
|
The Stream Control Transmission Protocol (SCTP) extension described in this document allows the support of a simple mechanism to distribute association requests between a cluster of SCTP end points providing the same service. In particular, this allows the use of anycast addresses in combination with SCTP. |
| | Payload Protocol Identifier based Fragmentation and Reassembly for the Stream Control Transmission Protocol |
| |
|
This document describes a method for the Stream Control Transmission Protocol (SCTP) allowing the upper layer to perform fragmentation, reassembly, and interleaving of large ordered user messages by using the payload protocol identifier (PPID). According to the base specification supporting fragmentation of large user messages is optional. And even if an SCTP implementation supports fragmentation, interleaving of user messages is not supported by the base specification. |
| | BGP SR Policy Extensions for Administrative Flags |
| |
|
Segment Routing is a source routing paradigm that explicitly indicates the forwarding path for packets at the ingress node. An SR Policy is a set of candidate paths, each consisting of one or more segment lists. This document defines an extension to the BGP SR Policy that sets the administrative state of the candidate path or segment list, facilitating the operation and maintenance of the SR Policy. |

| | Centralized Anycast Gateway in Ethernet VPN(EVPN) |
| |
|
EVPN Integrated Routing and Bridging (IRB) fabrics provide a flexible and extensible method for Layer-2 and Layer-3 overlay network connectivity. [EVPN-IRB] defines operation for symmetric and asymmetric EVPN IRB using distributed anycast gateway architecture (DAG). In a DAG architecture, both bridging and first-hop routing functions for overlay subnets are located on leaf PEs, with first-hop routing provided by a distributed anycast gateway provisioned across the leaf PEs. This document describes an architecture and operation for EVPN Centralized Anycast Gateway (CAG), which allows the first- hop routing function for overlay subnets to be centralized on designated IRB GWs while the bridging function is still located on the leaf PEs. The documents also covers trade-offs of deploying a CAG as compared with DAG. It further describes operation for inter- op between CAG and DAG based EVPN-IRB network overlays. |
| | An Interplanetary DNS Model |
| |
|
As human activity continues to spread beyond the Earth, so must the communications systems which support that activity continue to expand in scope. One such case, Internet naming, presents particular challenges when considering a multi-planet civilization. Proper operation of terrestrial DNS services and clients require constant, reasonably low latency connectivity to operate properly. These conditions are distinctly not present when considering interplanetary links; high latency and frequent disruption due to space weather events and general link availability prevail. To overcome these challenges in space networking, a delay and distruption tolerant (DTN) suite of protocols has been developed based on a store and forward mechanism, Bundle Protocol(BP). This DTN network, which optimizes to ensure bundle delivery, does not allow for end to end encapsulation of IP packets beyond terrestrial boundaries, as the latency still creates issues completing network transactions, even in the unlikely event of continuous link availability. |
| | BGP Extension for SR Segment List optimization |
| |
|
This document introduces an optimization method for segment list arrangement the SR Policy TLV of the BGP Tunnel Encapsulation Attribute. This optimization solves the problem of the Segment Routing's penultimate segment node being unable to perform the penultimate Segment Pop (PSP) behavior when the egress node has both End SID and service SID encapsulated in Segment Routing Header's segment List. This solution adds an E-Flag to the SRv6 SID Endpoint Behavior sub-TLV carried in Segment List Sub-TLV of the SR Policy TLV. This optimization can improve the forwarding efficiency of data packets when End SID and Service SID are present. |

The Stream Control Transmission Protocol (SCTP) supports multi-homing for providing network fault tolerance. However, mainly one path is used for data transmission. Only timer-based retransmissions are carried over other paths as well. This document describes how multiple paths can be used simultaneously for transmitting user messages. |
| | TCP SYN Extended Option Space Using an Out-of-Band Segment |
| |
|
This document describes an experimental method to extend the option space for connection parameters within the initial TCP SYN segment, at the start of a TCP connection. This method effectively extends the option space of an initial SYN by using an additional coupled segment that is sent 'out-of-band'. It complements the proposed Extended Data Offset (EDO) option that is applicable only after the initial segment. |

| | A UDP-based GMA (Generic Multi-Access) Protocol |
| |
|
A device can simultaneously connect to multiple access networks, e.g., Wi-Fi, LTE, 5G, DSL, and SATCOM (Satellite Communications). It is desirable to seamlessly combine multiple connections over these networks below the transport layer (L4) to improve quality of experience for applications that do not have built-in multi- path capabilities. This document presents a new convergence protocol for managing data traffic across multiple network paths. The solution has been developed by the authors based on their experiences in multiple standards bodies including IETF and 3GPP, is not an Internet Standard and does not represent the consensus opinion of the IETF. This document will enable other developers to build interoperable implementations to experiment with the protocol. |
| | Simplified MVPN for BIER and IR |
| |
|
Per RFC6513 and RFC6514, seven MCAST-VPN NLRIs and relevant procedures are defined to build multicast forwarding tree over the service provider backbone. RFC8556 introduces that MVPN can use BIER as PMSI tunnel to perform optimal multicast forwarding. However, the complicated NLRI exchange and the switching from I-PMSI to S-PMSI tunnel is not necessary for BIER and IR tunnel. The architectural advantages of BIER and IR cannot be fully utilized. Therefore, a new simplified MVPN for BIER and IR is proposed to substitute current NLRIs exchange and procedures. This document would like to discuss the value of the MVPN simplification and provide suggestive solution. |
| | EVPN Inter-Domain Option-B Solution |
| |
|
An EVPN Inter-Domain interconnect solution is required if two or more sites of the same Ethernet Virtual Private Network (EVPN) are attached to different IGP domains or Autonomous Systems (AS), and they need to communicate. The Inter-Domain Option-B connectivity model is one of the most popular solutions for such EVPN connectivity. While multiple documents refer to this type of interconnect solution and specify different aspects of it, there is no document that summarizes the impact of the Inter-Domain Option-B connectivity in the EVPN procedures. This document does not specify new procedures but analyses the EVPN procedures in an Inter-Domain Option-B network and suggests potential solutions for the described issues. Those solutions are based on either other specifications or based on local implementations that do not modify the end-to-end EVPN control plane. |
| | Merkle Tree Certificates for TLS |
| |
|
This document describes Merkle Tree certificates, a new certificate type for use with TLS. A relying party that regularly fetches information from a transparency service can use this certificate type as a size optimization over more conventional mechanisms with post- quantum signatures. Merkle Tree certificates integrate the roles of X.509 and Certificate Transparency, achieving comparable security properties with a smaller message size, at the cost of more limited applicability. |

This document describes a network diagnostic tool called PROBE. PROBE is similar to PING in that it can be used to query the status of a probed interface, but it differs from PING in that it does not require bidirectional connectivity between the probing and probed interfaces. Instead, PROBE requires bidirectional connectivity between the probing interface and a proxy interface. The proxy interface can reside on the same node as the probed interface, or it can reside on a node to which the probed interface is directly connected. This document updates RFC 4884 and obsoletes RFC 8335. |

This document specifies the GMA (Generic Multi-Access) traffic splitting control algorithm. The receiving endpoint measures one- way-delay, round-trip time, and delivery rate for multiple connections and determines how a data flow is split across them. When update is needed, it will send out a control message, aka Traffic Splitting Update (TSU), to notify the transmitting endpoint of the new traffic splitting configuration. Compared to other sender-based multi-path transport protocols, e.g. MPTCP, MPQUIC, the GMA traffic splitting algorithm is receiver-based and does not require per-packet feedback, e.g. Ack. It is designed specifically to support the Generic Multi-Access (GMA) convergence protocol as introduced in [MAMS] [GMA]. The solution has been developed by the authors based on their experiences in multiple standards bodies including IETF and 3GPP, is not an Internet Standard and does not represent the consensus opinion of the IETF. |

| | Header Protection for Cryptographically Protected E-mail |
| |
|
S/MIME version 3.1 introduced a mechanism to provide end-to-end cryptographic protection of e-mail message headers. However, few implementations generate messages using this mechanism, and several legacy implementations have revealed rendering or security issues when handling such a message. This document updates the S/MIME specification (RFC8551) to offer a different mechanism that provides the same cryptographic protections but with fewer downsides when handled by legacy clients. Furthermore, it offers more explicit usability, privacy, and security guidance for clients when generating or handling e-mail messages with cryptographic protection of message headers. The Header Protection scheme defined here is also applicable to messages with PGP/MIME cryptographic protections. |
| | Discovery of OSCORE Groups with the CoRE Resource Directory |
| |
|
Group communication over the Constrained Application Protocol (CoAP) can be secured by means of Group Object Security for Constrained RESTful Environments (Group OSCORE). At deployment time, devices may not know the exact security groups to join, the respective Group Manager, or other information required to perform the joining process. This document describes how a CoAP endpoint can use descriptions and links of resources registered at the CoRE Resource Directory to discover security groups and to acquire information for joining them through the respective Group Manager. A given security group may protect multiple application groups, which are separately announced in the Resource Directory as sets of endpoints sharing a pool of resources. This approach is consistent with, but not limited to, the joining of security groups based on the ACE framework for Authentication and Authorization in constrained environments. |

| | the extensions of BGP-LS to carry security capabilities |
| |
|
As users' traffic faces more unpredictable attacks during transmission, there are more and more end-users now need high security data transmission guarantee, they need ISPs to provide security protection capabilities on the data forwarding path, but it is very difficult for operators to manage the security attributes of nodes through control surfaces. ISPs need to have real-time awareness of the security capabilities available in the network, then form a security capability map, finally provide security protection for users at the routing level. The goal of this draft is to collect the security capabilities of nodes, which will be one of the factors to form the routing topology, and use the routing programming capabilities to form a secure routing path. The security capability includes healthy information(such as the device software is up-to-date), security service information, device information(such as the manufacturer information of the equipment). The BGP-LS protocol is extended to carry the security capabilities of the node. The controller collects topology information, forms a topology path with security capabilities according to security requirements, and supports SRv6 path sending to execute node forwarding through programming. |
| | Source IPv6 Address Programmability |
| |

IPv6-based tunneling technologies, such as SRv6, have been deployed by provider on transport networks to provide users with services such as VPN and SD-WAN. After the service traffic enters the provider's transport network, it will be encapsulated by tunnel (SRv6 encapsulation). In order to better meet the SLA requirements of users, some technologies need to carry relevant information along with the flow to guide the processing of packets during forwarding. This document discusses the programmability of IPv6 source addresses to carry the necessary flow information |

This document specifies a set of objects extending the Content Delivery Network Interconnection (CDNI) metadata model to allow for metadata to be applied conditionally and at various points in a dCDNs processing of requests. The concept of Processing Stages are introduced, where each stage in a CDN's processing pipeline presents an opportunity to examine requests and responses and make alterations as needed. Metadata, such as caching rules, can be applied conditionally (based on aspects of an HTTP request header), and HTTP responses from a source can be altered dynamically (such as adding or dropping an HTTP header). This standard leverages the expression language documented in the Metadata Expression Language (MEL) Specification. |
| | A Multiplane Architecture Proposal for the Quantum Internet |
| |
|
A consistent reference architecture model for the Quantum Internet is required to progress in its evolution, providing a framework for the integration of the protocols applicable to it, and enabling the advance of the applications based on it. This model has to satisfy three essential requirements: agility, so it is able to adapt to the evolution of quantum communications base technologies, sustainability, with open availability in technological and economical terms, and pliability, being able to integrate with the operations and management procedures in current networks. This document proposes such an architecture framework, with the goal of providing a conceptual common framework for the integration of technologies intended to build the Quantum Internet infrastructure and its integration with the current Internet. The framework is based on the already extensive experience in the deployment of QKD network infrastructures and on related initiatives focused on the integration of network infrastructures and services. |

| | Interworking of GMPLS Control and Centralized Controller Systems |
| |
|
Generalized Multi-Protocol Label Switching (GMPLS) control allows each network element (NE) to perform local resource discovery, routing and signaling in a distributed manner. The advancement of software-defined transport networking technology enables a group of NEs to be managed through centralized controller hierarchies. This helps to tackle challenges arising from multiple domains, vendors, and technologies. An example of such a centralized architecture is the Abstraction and Control of Traffic Engineered Networks (ACTN) controller hierarchy, as described in RFC 8453. Both the distributed and centralized control planes have their respective advantages and should complement each other in the system, rather than competing. This document outlines how the GMPLS distributed control plane can work together with a centralized controller system in a transport network. |

This document contains the R^5N DHT technical specification. R^5N is a secure distributed hash table (DHT) routing algorithm and data structure for decentralized applications. It features an open peer- to-peer overlay routing mechanism which supports ad-hoc permissionless participation and support for topologies in restricted-route environments. Optionally, the paths data takes through the overlay can be recorded, allowing decentralized applications to use the DHT to discover routes. This document defines the normative wire format of protocol messages, routing algorithms, cryptographic routines and security considerations for use by implementers. This specification was developed outside the IETF and does not have IETF consensus. It is published here to guide implementation of R^5N and to ensure interoperability among implementations including the pre-existing GNUnet implementation. |

Concise Binary Object Representation Maintenance and Extensions (cbor) |
|
The Concise Binary Object Representation (CBOR, RFC 8949 == STD 94) is a data format whose design goals include the possibility of extremely small code size, fairly small message size, and extensibility without the need for version negotiation. CBOR does not provide any forms of data compression. CBOR data items, in particular when generated from legacy data models, often allow considerable gains in compactness when applying data compression. While traditional data compression techniques such as DEFLATE (RFC 1951) can work well for CBOR encoded data items, their disadvantage is that the recipient needs to decompress the compressed form to make use of the data. This specification describes Packed CBOR, a simple transformation of a CBOR data item into another CBOR data item that is almost as easy to consume as the original CBOR data item. A separate decompression step is therefore often not required at the recipient. // The present version (-13) is a refresh of the implementation draft // -12 with minor editorial improvements. |

Concise Binary Object Representation Maintenance and Extensions (cbor) |
|
At the time of writing, the Concise Data Definition Language (CDDL) is defined by RFC 8610 and RFC 9165. The latter has used the extension point provided in RFC 8610, the _control operator_. As CDDL is being used in larger projects, the need for features has become known that cannot be easily mapped into this single extension point. The present document defines a backward- and forward-compatible way to add a module structure to CDDL. |

| | CoAP: Non-traditional response forms |
| |
|
In CoAP as defined by RFC 7252, responses are always unicast back to a client that posed a request. The present memo describes two forms of responses that go beyond that model. These descriptions are not intended as advocacy for adopting these approaches immediately, they are provided to point out potential avenues for development that would have to be carefully evaluated. |
| | The "dereferenceable identifier" pattern |
| |
|
In a protocol or an application environment, it is often important to be able to create unambiguous identifiers for some meaning (concept or some entity). Due to the simplicity of creating URIs, these have become popular for this purpose. Beyond the purpose of identifiers to be uniquely associated with a meaning, some of these URIs are in principle _dereferenceable_, so something can be placed that can be retrieved when encountering such a URI. // The present revision -04 includes a few clarifications. |

Large language models (LLMs) like ChatGPT have become increasingly popular in recent years due to their impressive performance in various natural language processing tasks. These models are built by training deep neural networks on massive amounts of text data, often consisting of billions or even trillions of parameters. However, the training process for these models can be extremely resource- intensive, requiring the deployment of thousands or even tens of thousands of GPUs in a single AI training cluster. Therefore, three- stage or even five-stage CLOS networks are commonly adopted for AI networks. The non-blocking nature of the network become increasingly critical for large-scale AI models. Therefore, adaptive routing is necessary to dynamically distribute traffic to the same destination over multiple equal-cost paths, based on network capacity and even congestion information along those paths. |
| | Using ShangMi in the Internet Key Exchange Protocol Version 2 (IKEv2) |
| |
|
This document defines a set of cryptographic transforms for use in the Internet Key Exchange Protocol version 2 (IKEv2). The transforms are based on ISO and Chinese cryptographic standard algorithms (called "ShangMi" or “SM” algorithms). The use of these algorithms with IKEv2 is not endorsed by the IETF. The SM algorithms is ISO standardization and are mandatory for some scenario in China, so this document provides a description of how to use the SM algorithms with IKEv2 and specifies a set of cryptographic transforms so that implementers can produce interworking implementations. |
