| Status: | INFORMATIONAL |
| DOI: | 10.17487/RFC 8604 |
|
This document describes an application of Segment Routing to scale the network to support hundreds of thousands of network nodes, and tens of millions of physical underlay endpoints. This use case can be applied to the interconnection of massive-scale Data Centers (DCs) and/or large aggregation networks. Forwarding tables of midpoint and leaf nodes only require a few tens of thousands of entries. This may be achieved by the inherently scaleable nature of Segment Routing and the design proposed in this document. |

| RFC 8617 | The Authenticated Received Chain (ARC) Protocol |
| |
| Authors: | K. Andersen, B. Long, Ed., S. Blank, Ed., M. Kucherawy, Ed.. |
| Date: | July 2019 |
| Formats: | txt json html |
| Status: | EXPERIMENTAL |
| DOI: | 10.17487/RFC 8617 |
|
The Authenticated Received Chain (ARC) protocol provides an authenticated "chain of custody" for a message, allowing each entity that handles the message to see what entities handled it before and what the message's authentication assessment was at each step in the handling.
ARC allows Internet Mail Handlers to attach assertions of message authentication assessment to individual messages. As messages traverse ARC-enabled Internet Mail Handlers, additional ARC assertions can be attached to messages to form ordered sets of ARC assertions that represent the authentication assessment at each step of the message-handling paths.
ARC-enabled Internet Mail Handlers can process sets of ARC assertions to inform message disposition decisions, identify Internet MailHandlers that might break existing authentication mechanisms, and convey original authentication assessments across trust boundaries. |

| |
| RFC 8622 | A Lower-Effort Per-Hop Behavior (LE PHB) for Differentiated Services |
| |
|
|
This document specifies properties and characteristics of a Lower-Effort Per-Hop Behavior (LE PHB). The primary objective of this LEPHB is to protect Best-Effort (BE) traffic (packets forwarded with the default PHB) from LE traffic in congestion situations, i.e., when resources become scarce, BE traffic has precedence over LE traffic and may preempt it. Alternatively, packets forwarded by the LE PHB can be associated with a scavenger service class, i.e., they scavenge otherwise-unused resources only. There are numerous uses for thisPHB, e.g., for background traffic of low precedence, such as bulk data transfers with low priority in time, non-time-critical backups, larger software updates, web search engines while gathering information from web servers and so on. This document recommends a standard Differentiated Services Code Point (DSCP) value for the LEPHB.
This specification obsoletes RFC 3662 and updates the DSCP recommended in RFCs 4594 and 8325 to use the DSCP assigned in this specification. |

| RFC 8627 | RTP Payload Format for Flexible Forward Error Correction (FEC) |
| |
| Authors: | M. Zanaty, V. Singh, A. Begen, G. Mandyam. |
| Date: | July 2019 |
| Formats: | txt json html |
| Status: | PROPOSED STANDARD |
| DOI: | 10.17487/RFC 8627 |
|
This document defines new RTP payload formats for the Forward ErrorCorrection (FEC) packets that are generated by the non-interleaved and interleaved parity codes from source media encapsulated in RTP.These parity codes are systematic codes (Flexible FEC, or "FLEXFEC"), where a number of FEC repair packets are generated from a set of source packets from one or more source RTP streams. These FEC repair packets are sent in a redundancy RTP stream separate from the source RTP stream(s) that carries the source packets. RTP source packets that were lost in transmission can be reconstructed using the source and repair packets that were received. The non-interleaved and interleaved parity codes that are defined in this specification offer a good protection against random and bursty packet losses, respectively, at a cost of complexity. The RTP payload formats that are defined in this document address scalability issues experienced with the earlier specifications and offer several improvements. Due to these changes, the new payload formats are not backward compatible with earlier specifications; however, endpoints that do not implement this specification can still work by simply ignoring the FEC repair packets. |

| Obsoletes: | RFC 7730 |
| Status: | PROPOSED STANDARD |
| DOI: | 10.17487/RFC 8630 |
|
This document defines a Trust Anchor Locator (TAL) for the ResourcePublic Key Infrastructure (RPKI). The TAL allows Relying Parties in the RPKI to download the current Trust Anchor (TA) CertificationAuthority (CA) certificate from one or more locations and verify that the key of this self-signed certificate matches the key on the TAL.Thus, Relying Parties can be configured with TA keys but can allow these TAs to change the content of their CA certificate. In particular, it allows TAs to change the set of IP Address Delegations and/or Autonomous System Identifier Delegations included in the extension(s) (RFC 3779) of their certificate.
This document obsoletes the previous definition of the TAL as provided in RFC 7730 by adding support for Uniform ResourceIdentifiers (URIs) (RFC 3986) that use HTTP over TLS (HTTPS) (RFC7230) as the scheme. |

Many resources provided on the Web are part of sets of resources that are provided in a context that is managed by one particular service provider. Often, these sets of resources are referred to as "Web services" or "Web APIs". This specification defines link relations that represent relationships from Web services or APIs to resources that provide documentation, descriptions, metadata, or status information for these resources. Documentation is primarily intended for human consumers, whereas descriptions are primarily intended for automated consumers. Metadata provides information about a service's context. This specification also defines a link relation to identify status resources that are used to represent information about service status. |

Well-known BGP communities are manipulated differently across various current implementations, resulting in difficulties for operators.Network operators should deploy consistent community handling across their networks while taking the inconsistent behaviors from the various BGP implementations into consideration. This document recommends specific actions to limit future inconsistency: namely,BGP implementors must not create further inconsistencies from this point forward. These behavioral changes, though subtle, actually update RFC 1997. |

Opportunistic Secure Real-time Transport Protocol (OSRTP) is an implementation of the Opportunistic Security mechanism, as defined inRFC 7435, applied to the Real-time Transport Protocol (RTP). OSRTP allows encrypted media to be used in environments where support for encryption is not known in advance and is not required. OSRTP does not require Session Description Protocol (SDP) extensions or features and is fully backwards compatible with existing implementations using encrypted and authenticated media and implementations that do not encrypt or authenticate media packets. OSRTP is not specific to any key management technique for Secure RTP (SRTP). OSRTP is a transitional approach useful for migrating existing deployments of real-time communications to a fully encrypted and authenticated state. |

A certain maximum amount of data can be safely encrypted when encryption is performed under a single key. This amount is called the "key lifetime". This specification describes a variety of methods for increasing the lifetime of symmetric keys. It provides two types of re-keying mechanisms based on hash functions and block ciphers that can be used with modes of operations such as CTR, GCM,CBC, CFB, and OMAC.

Applications differ with respect to whether they need session continuity and/or IP address reachability. The network providing the same type of service to any mobile host and any application running on the host yields inefficiencies, as described in RFC 7333. This document defines a new concept of enabling applications to influence the network's mobility services (session continuity and/or IP address reachability) on a per-socket basis, and suggests extensions to the networking stack's API to accommodate this concept. |

The BGP specification (RFC 4271) mandates a maximum BGP message size of 4,096 octets. As BGP is extended to support new Address FamilyIdentifiers (AFIs), Subsequent AFIs (SAFIs), and other features, there is a need to extend the maximum message size beyond 4,096 octets. This document updates the BGP specification by extending the maximum message size from 4,096 octets to 65,535 octets for all messages except for OPEN and KEEPALIVE messages. |

This document provides the overall architecture for DeterministicNetworking (DetNet), which provides a capability to carry specified unicast or multicast data flows for real-time applications with extremely low data loss rates and bounded latency within a network domain. Techniques used include 1) reserving data-plane resources for individual (or aggregated) DetNet flows in some or all of the intermediate nodes along the path of the flow, 2) providing explicit routes for DetNet flows that do not immediately change with the network topology, and 3) distributing data from DetNet flow packets over time and/or space to ensure delivery of each packet's data in spite of the loss of a path. DetNet operates at the IP layer and delivers service over lower-layer technologies such as MPLS and Time-Sensitive Networking (TSN) as defined by IEEE 802.1. |

| RFC 8656 | Traversal Using Relays around NAT (TURN): Relay Extensions to Session Traversal Utilities for NAT (STUN) |
| |
|
|
If a host is located behind a NAT, it can be impossible for that host to communicate directly with other hosts (peers) in certain situations. In these situations, it is necessary for the host to use the services of an intermediate node that acts as a communication relay. This specification defines a protocol, called "TraversalUsing Relays around NAT" (TURN), that allows the host to control the operation of the relay and to exchange packets with its peers using the relay. TURN differs from other relay control protocols in that it allows a client to communicate with multiple peers using a single relay address.
The TURN protocol was designed to be used as part of the InteractiveConnectivity Establishment (ICE) approach to NAT traversal, though it can also be used without ICE.

|
The Certification Authority Authorization (CAA) DNS record allows a domain to communicate an issuance policy to Certification Authorities(CAs) but only allows a domain to define a policy with CA-level granularity. However, the CAA specification (RFC 8659) also provides facilities for an extension to admit a more granular, CA-specific policy. This specification defines two such parameters: one allowing specific accounts of a CA to be identified by URIs and one allowing specific methods of domain control validation as defined by theAutomatic Certificate Management Environment (ACME) protocol to be required. |

IPv4-over-IPv6 transition mechanisms provide IPv4 connectivity services over IPv6 native networks during the IPv4/IPv6 coexistence period. DHCPv6 options have been defined to configure clients forLightweight 4over6, Mapping of Address and Port with Encapsulation(MAP-E), Mapping of Address and Port using Translation (MAP-T) unicast softwire mechanisms, and multicast softwires. However, in many networks, configuration information is stored in anAuthentication, Authorization, and Accounting (AAA) server, which utilizes the Remote Authentication Dial In User Service (RADIUS) protocol to provide centralized management for users. When a new transition mechanism is developed, new RADIUS attributes need to be defined correspondingly.
This document defines new RADIUS attributes to carry softwire configuration parameters based on Address plus Port from a AAA server to a Broadband Network Gateway. Both unicast and multicast attributes are covered. |

A Segment Routing (SR) node steers a packet through a controlled set of instructions, called segments, by prepending the packet with an SR header. A segment can represent any instruction, topological or service based. SR allows enforcing a flow through any topological path while maintaining per-flow state only at the ingress node to theSR domain.
The Segment Routing architecture can be directly applied to the MPLS data plane with no change in the forwarding plane. This document describes how Segment Routing MPLS operates in a network where LDP is deployed and in the case where SR-capable and non-SR-capable nodes coexist. |

MPLS Segment Routing (SR-MPLS) is a method of source routing a packet through an MPLS data plane by imposing a stack of MPLS labels on the packet to specify the path together with any packet-specific instructions to be executed on it. SR-MPLS can be leveraged to realize a source-routing mechanism across MPLS, IPv4, and IPv6 data planes by using an MPLS label stack as a source-routing instruction set while making no changes to SR-MPLS specifications and interworking with SR-MPLS implementations.
This document describes how SR-MPLS-capable routers and IP-only routers can seamlessly coexist and interoperate through the use ofSR-MPLS label stacks and IP encapsulation/tunneling such as MPLS- over-UDP as defined in RFC 7510. |

Segment Routing (SR) enables any head-end node to select any path without relying on a hop-by-hop signaling technique (e.g., LDP orRSVP-TE). It depends only on "segments" that are advertised by link- state Interior Gateway Protocols (IGPs). An SR path can be derived from a variety of mechanisms, including an IGP Shortest Path Tree(SPT), an explicit configuration, or a Path Computation Element(PCE). This document specifies extensions to the Path ComputationElement Communication Protocol (PCEP) that allow a stateful PCE to compute and initiate Traffic-Engineering (TE) paths, as well as aPath Computation Client (PCC) to request a path subject to certain constraints and optimization criteria in SR networks.

Segment Routing (SR) leverages the source-routing paradigm. A node steers a packet through an ordered list of instructions called"segments". A segment can represent any instruction, topological or service based. The ingress node prepends an SR header to a packet containing a set of segment identifiers (SIDs). Each SID represents a topological or service-based instruction. Per-flow state is maintained only on the ingress node of the SR domain. An "SR domain" is defined as a single administrative domain for global SID assignment.

| RFC 8672 | TLS Server Identity Pinning with Tickets |
| |
|
|
Misissued public-key certificates can prevent TLS clients from appropriately authenticating the TLS server. Several alternatives have been proposed to detect this situation and prevent a client from establishing a TLS session with a TLS end point authenticated with an illegitimate public-key certificate. These mechanisms are either not widely deployed or limited to public web browsing.
This document proposes experimental extensions to TLS with opaque pinning tickets as a way to pin the server's identity. During an initial TLS session, the server provides an original encrypted pinning ticket. In subsequent TLS session establishment, upon receipt of the pinning ticket, the server proves its ability to decrypt the pinning ticket and thus the ownership of the pinning protection key. The client can now safely conclude that the TLS session is established with the same TLS server as the original TLS session. One of the important properties of this proposal is that no manual management actions are required. |

This document specifies the initial version of a YANG module "iana- tunnel-type", which contains a collection of IANA-maintained YANG identities used as interface types for tunnel interfaces. The module reflects the "tunnelType" registry maintained by IANA. The latest revision of this YANG module can be obtained from the IANA website.
Tunnel type values are not directly added to the Tunnel InterfaceTypes YANG module; they must instead be added to the "tunnelType"IANA registry. Once a new tunnel type registration is made by IANA for a new tunneling scheme or even an existing one that is not already listed in the current registry (e.g., LISP, NSH), IANA will update the Tunnel Interface Types YANG module accordingly.
Some of the IETF-defined tunneling techniques are not listed in the current IANA registry. It is not the intent of this document to update the existing IANA registry with a comprehensive list of tunnel technologies. Registrants must follow the IETF registration procedure for interface types whenever a new tunnel type is needed. |

Adoption of cloud and fog technology allows operators to deploy a single "Service Function" (SF) to multiple "execution locations".The decision to steer traffic to a specific location may change frequently based on load, proximity, etc. Under the current ServiceFunction Chaining (SFC) framework, steering traffic dynamically to the different execution endpoints requires a specific "rechaining", i.e., a change in the service function path reflecting the differentIP endpoints to be used for the new execution points. This procedure may be complex and take time. In order to simplify rechaining and reduce the time to complete the procedure, we discuss separating the logical Service Function Path (SFP) from the specific execution endpoints. This can be done by identifying the SFs using a name rather than a routable IP endpoint (or Layer 2 address). This document describes the necessary extensions, additional functions, and protocol details in the Service Function Forwarder (SFF) to handle name-based relationships.
This document presents InterDigital's approach to name-based SFC. It does not represent IETF consensus and is presented here so that theSFC community may benefit from considering this mechanism and the possibility of its use in the edge data centers. |

Connecting an enterprise site to multiple ISPs over IPv6 using provider-assigned addresses is difficult without the use of some form of Network Address Translation (NAT). Much has been written on this topic over the last 10 to 15 years, but it still remains a problem without a clearly defined or widely implemented solution. Any multihoming solution without NAT requires hosts at the site to have addresses from each ISP and to select the egress ISP by selecting a source address for outgoing packets. It also requires routers at the site to take into account those source addresses when forwarding packets out towards the ISPs.
This document examines currently available mechanisms for providing a solution to this problem for a broad range of enterprise topologies.It covers the behavior of routers to forward traffic by taking into account source address, and it covers the behavior of hosts to select appropriate default source addresses. It also covers any possible role that routers might play in providing information to hosts to help them select appropriate source addresses. In the process of exploring potential solutions, this document also makes explicit requirements for how the solution would be expected to behave from the perspective of an enterprise site network administrator. |

This document specifies a fast reroute framework for protecting IP/MPLS services and MPLS transport tunnels against egress node and egress link failures. For each type of egress failure, it defines the roles of Point of Local Repair (PLR), protector, and backup egress router and the procedures of establishing a bypass tunnel from a PLR to a protector. It describes the behaviors of these routers in handling an egress failure, including local repair on the PLR and context-based forwarding on the protector. The framework can be used to develop egress protection mechanisms to reduce traffic loss before global repair reacts to an egress failure and control-plane protocols converge on the topology changes due to the egress failure. |

| RFC 8680 | Forward Error Correction (FEC) Framework Extension to Sliding Window Codes |

RFC 6363 describes a framework for using Forward Error Correction(FEC) codes to provide protection against packet loss. The framework supports applying FEC to arbitrary packet flows over unreliable transport and is primarily intended for real-time, or streaming, media. However, FECFRAME as per RFC 6363 is restricted to block FEC codes. This document updates RFC 6363 to support FEC codes based on a sliding encoding window, in addition to block FEC codes, in a backward-compatible way. During multicast/broadcast real-time content delivery, the use of sliding window codes significantly improves robustness in harsh environments, with less repair traffic and lower FEC-related added latency. |

| RFC 8681 | Sliding Window Random Linear Code (RLC) Forward Erasure Correction (FEC) Schemes for FECFRAME |
| |
|
|
This document describes two fully specified Forward ErasureCorrection (FEC) Schemes for Sliding Window Random Linear Codes(RLC), one for RLC over the Galois Field (a.k.a., Finite Field)GF(2), a second one for RLC over the Galois Field GF(2^(8)), each time with the possibility of controlling the code density. They can protect arbitrary media streams along the lines defined by FECFRAME extended to Sliding Window FEC Codes. These Sliding Window FEC Codes rely on an encoding window that slides over the source symbols, generating new repair symbols whenever needed. Compared to block FEC codes, these Sliding Window FEC Codes offer key advantages with real- time flows in terms of reduced FEC-related latency while often providing improved packet erasure recovery capabilities. |

| Authors: | M. Saito, M. Matsumoto, V. Roca, Ed., E. Baccelli. |

| Status: | PROPOSED STANDARD |
| DOI: | 10.17487/RFC 8682 |
|
This document describes the TinyMT32 Pseudorandom Number Generator(PRNG), which produces 32-bit pseudorandom unsigned integers and aims at having a simple-to-use and deterministic solution. This PRNG is a small-sized variant of the Mersenne Twister (MT) PRNG. The main advantage of TinyMT32 over MT is the use of a small internal state, compatible with most target platforms that include embedded devices, while keeping reasonably good randomness that represents a significant improvement compared to the Park-Miller LinearCongruential PRNG. However, neither the TinyMT nor MT PRNG is meant to be used for cryptographic applications. |

| RFC 8683 | Additional Deployment Guidelines for NAT64/464XLAT in Operator and Enterprise Networks |
| |
|
|
This document describes how Network Address and Protocol Translation from IPv6 Clients to IPv4 Servers (NAT64) (including 464XLAT) can be deployed in an IPv6 network -- whether it's cellular ISP, broadbandISP, or enterprise -- and the possible optimizations. This document also discusses issues to be considered when having IPv6-only connectivity, such as: a) DNS64, b) applications or devices that use literal IPv4 addresses or non-IPv6-compliant APIs, and c) IPv4-only hosts or applications. |

| RFC 8684 | TCP Extensions for Multipath Operation with Multiple Addresses |

| Authors: | A. Ford, C. Raiciu, M. Handley, O. Bonaventure, C. Paasch. |
| Date: | March 2020 |

| Obsoletes: | RFC 6824 |
| Status: | PROPOSED STANDARD |
| DOI: | 10.17487/RFC 8684 |
|
TCP/IP communication is currently restricted to a single path per connection, yet multiple paths often exist between peers. The simultaneous use of these multiple paths for a TCP/IP session would improve resource usage within the network and thus improve user experience through higher throughput and improved resilience to network failure.
Multipath TCP provides the ability to simultaneously use multiple paths between peers. This document presents a set of extensions to traditional TCP to support multipath operation. The protocol offers the same type of service to applications as TCP (i.e., a reliable bytestream), and it provides the components necessary to establish and use multiple TCP flows across potentially disjoint paths.
This document specifies v1 of Multipath TCP, obsoleting v0 as specified in RFC 6824, through clarifications and modifications primarily driven by deployment experience. |

The Hierarchical Path Computation Element (H-PCE) architecture is defined in RFC 6805. It provides a mechanism to derive an optimum end-to-end path in a multi-domain environment by using a hierarchical relationship between domains to select the optimum sequence of domains and optimum paths across those domains.
This document defines extensions to the Path Computation ElementCommunication Protocol (PCEP) to support H-PCE procedures. |

| RFC 8686 | Application-Layer Traffic Optimization (ALTO) Cross-Domain Server Discovery |
| |
| Authors: | S. Kiesel, M. Stiemerling. |
| Date: | February 2020 |
| Formats: | txt html json pdf xml |
| Status: | PROPOSED STANDARD |
| DOI: | 10.17487/RFC 8686 |
|
The goal of Application-Layer Traffic Optimization (ALTO) is to provide guidance to applications that have to select one or several hosts from a set of candidates capable of providing a desired resource. ALTO is realized by a client-server protocol. Before anALTO client can ask for guidance, it needs to discover one or moreALTO servers that can provide suitable guidance.
In some deployment scenarios, in particular if the information about the network topology is partitioned and distributed over several ALTO servers, it may be necessary to discover an ALTO server outside of the ALTO client's own network domain, in order to get appropriate guidance. This document details applicable scenarios, itemizes requirements, and specifies a procedure for ALTO cross-domain server discovery.
Technically, the procedure specified in this document takes oneIP address or prefix and a U-NAPTR Service Parameter (typically,"ALTO:https") as parameters. It performs DNS lookups (for NAPTR resource records in the "in-addr.arpa." or "ip6.arpa." trees) and returns one or more URIs of information resources related to that IP address or prefix. |

| RFC 8687 | OSPF Routing with Cross-Address Family Traffic Engineering Tunnels |
| |
|
|
When using Traffic Engineering (TE) in a dual-stack IPv4/IPv6 network, the Multiprotocol Label Switching (MPLS) TE Label SwitchedPath (LSP) infrastructure may be duplicated, even if the destinationIPv4 and IPv6 addresses belong to the same remote router. In order to achieve an integrated MPLS TE LSP infrastructure, OSPF routes must be computed over MPLS TE tunnels created using information propagated in another OSPF instance. This issue is solved by advertising cross- address family (X-AF) OSPF TE information.
This document describes an update to RFC 5786 that allows for the easy identification of a router's local X-AF IP addresses. |

| RFC 8688 | A Session Initiation Protocol (SIP) Response Code for Rejected Calls |
| |
| Authors: | E.W. Burger, B. Nagda. |
| Date: | December 2019 |
| Formats: | txt json html pdf xml |
| Status: | PROPOSED STANDARD |
| DOI: | 10.17487/RFC 8688 |
|
This document defines the 608 (Rejected) Session Initiation Protocol(SIP) response code. This response code enables calling parties to learn that an intermediary rejected their call attempt. No one will deliver, and thus answer, the call. As a 6xx code, the caller will be aware that future attempts to contact the same User Agent Server will likely fail. The initial use case driving the need for the 608 response code is when the intermediary is an analytics engine. In this case, the rejection is by a machine or other process. This contrasts with the 607 (Unwanted) SIP response code in which a human at the target User Agent Server indicates the user did not want the call. In some jurisdictions, this distinction is important. This document also defines the use of the Call-Info header field in 608 responses to enable rejected callers to contact entities that blocked their calls in error. This provides a remediation mechanism for legal callers that find their calls blocked. |

| RFC 8689 | SMTP Require TLS Option |
| |
|
|
The SMTP STARTTLS option, used in negotiating transport-level encryption of SMTP connections, is not as useful from a security standpoint as it might be because of its opportunistic nature; message delivery is, by default, prioritized over security. This document describes an SMTP service extension, REQUIRETLS, and a message header field, TLS-Required. If the REQUIRETLS option or TLS-Required message header field is used when sending a message, it asserts a request on the part of the message sender to override the default negotiation of TLS, either by requiring that TLS be negotiated when the message is relayed or by requesting that recipient-side policy mechanisms such as MTA-STS and DNS-BasedAuthentication of Named Entities (DANE) be ignored when relaying a message for which security is unimportant. |

| Status: | PROPOSED STANDARD |
| DOI: | 10.17487/RFC 8690 |
|
RFC 8287 defines the extensions to perform LSP Ping and Traceroute for Segment Routing IGP-Prefix and IGP-Adjacency Segment Identifiers(SIDs) with the MPLS data plane. RFC 8287 proposes three TargetForwarding Equivalence Class (FEC) Stack sub-TLVs. While RFC 8287 defines the format and procedure to handle those sub-TLVs, it does not sufficiently clarify how the length of the Segment ID sub-TLVs should be computed to be included in the Length field of the sub-TLVs. This ambiguity has resulted in interoperability issues.
This document updates RFC 8287 by clarifying the length of each of the Segment ID sub-TLVs defined in RFC 8287. |

| RFC 8696 | Using Pre-Shared Key (PSK) in the Cryptographic Message Syntax (CMS) |
| |
|
|
The invention of a large-scale quantum computer would pose a serious challenge for the cryptographic algorithms that are widely deployed today. The Cryptographic Message Syntax (CMS) supports key transport and key agreement algorithms that could be broken by the invention of such a quantum computer. By storing communications that are protected with the CMS today, someone could decrypt them in the future when a large-scale quantum computer becomes available. Once quantum-secure key management algorithms are available, the CMS will be extended to support the new algorithms if the existing syntax does not accommodate them. This document describes a mechanism to protect today's communication from the future invention of a large-scale quantum computer by mixing the output of key transport and key agreement algorithms with a pre-shared key. |

This document introduces a generic mechanism to create a grouping ofLabel Switched Paths (LSPs) in the context of a Path ComputationElement (PCE). This grouping can then be used to define associations between sets of LSPs or between a set of LSPs and a set of attributes(such as configuration parameters or behaviors), and it is equally applicable to the stateful PCE (active and passive modes) and the stateless PCE. |

| Status: | EXPERIMENTAL |
| DOI: | 10.17487/RFC 8698 |
|
This document describes Network-Assisted Dynamic Adaptation (NADA), a novel congestion control scheme for interactive real-time media applications such as video conferencing. In the proposed scheme, the sender regulates its sending rate, based on either implicit or explicit congestion signaling, in a unified approach. The scheme can benefit from Explicit Congestion Notification (ECN) markings from network nodes. It also maintains consistent sender behavior in the absence of such markings by reacting to queuing delays and packet losses instead. |

|
When multiple congestion-controlled Real-time Transport Protocol(RTP) sessions traverse the same network bottleneck, combining their controls can improve the total on-the-wire behavior in terms of delay, loss, and fairness. This document describes such a method for flows that have the same sender, in a way that is as flexible and simple as possible while minimizing the number of changes needed to existing RTP applications. This document also specifies how to apply the method for the Network-Assisted Dynamic Adaptation (NADA) congestion control algorithm and provides suggestions on how to apply it to other congestion control algorithms. |
