 Multicast YANG Data Model
 
 draft-ietf-mboned-multicast-yang-model-13.txt
 Date: 07/05/2025
 Authors: Zheng Zhang, Cui(Linda) Wang, Ying Cheng, Xufeng Liu, Mahesh Sivakumar
 Working Group: MBONE Deployment (mboned)
 This document provides a generic multicast YANG data model that shows the relevant technologies or protocols used by multicast streams. It provides a management view for network administrators to obtain information about multicast services.
 Asymmetric Manifest Based Integrity
 
 draft-ietf-mboned-ambi-04.txt
 Date: 07/05/2025
 Authors: Jake Holland, Kyle Rose, Max Franke
 Working Group: MBONE Deployment (mboned)
 This document defines Asymmetric Manifest-Based Integrity (AMBI). AMBI allows each receiver or forwarder of a stream of multicast packets to check the integrity of the contents of each packet in the data stream. AMBI operates by passing cryptographically verifiable hashes of the data packets inside manifest messages, and sending the manifests over authenticated out-of-band communication channels.
 Discovery Of Restconf Metadata for Source-specific multicast
 
 draft-ietf-mboned-dorms-06.txt
 Date: 05/07/2025
 Authors: Jake Holland, Kyle Rose, Max Franke
 Working Group: MBONE Deployment (mboned)
 This document defines DORMS (Discovery Of Restconf Metadata for Source-specific multicast), a method to discover and retrieve extensible metadata about source-specific multicast channels using RESTCONF. The reverse IP DNS zone for a multicast sender's IP address is configured to use SRV resource records to advertise the hostname of a RESTCONF server that publishes metadata according to a new YANG module with support for extensions. A new service name and the new YANG module are defined.
 Circuit Breaker Assisted Congestion Control
 
 draft-ietf-mboned-cbacc-05.txt
 Date: 08/05/2025
 Authors: Jake Holland, Kyle Rose, Max Franke
 Working Group: MBONE Deployment (mboned)
 This document specifies Circuit Breaker Assisted Congestion Control (CBACC). CBACC enables fast-trip Circuit Breakers by publishing rate metadata about multicast channels from senders to intermediate network nodes or receivers. The circuit breaker behavior is defined as a supplement to receiver driven congestion control systems, to preserve network health if misbehaving or malicious receiver applications subscribe to a volume of traffic that exceeds capacity policies or capability for a network or receiving device.
 Multicast Redundant Ingress Router Failover
 
 draft-ietf-mboned-redundant-ingress-failover-07.txt
 Date: 04/07/2025
 Authors: Greg Shepherd, Zheng Zhang, Yisong Liu, Ying Cheng, Gyan Mishra
 Working Group: MBONE Deployment (mboned)
 This document analyzes the redundant ingress router failover problem of a multicast domain, and analyzes the possible backup modes and advantages of each mode when deploying multiple ingress devices to forward the same multicast flow in a multicast domain.
 YANG Data Model for Automatic Multicast Tunneling
 
 draft-ietf-mboned-amt-yang-04.txt
 Date: 07/07/2025
 Authors: Yisong Liu, Changwang Lin, Zheng Zhang, Xuesong Geng, Vinod Nagaraj
 Working Group: MBONE Deployment (mboned)
 This document defines YANG data models for the configuration and management of Automatic Multicast Tunneling (AMT) protocol operations.
 Non-source-routed Multicast in SR Networks
 
 draft-ietf-mboned-non-source-routed-sr-mcast-02.txt
 Date: 23/04/2025
 Authors: Zhaohui Zhang, IJsbrand Wijnands, Hooman Bidgoli, Yisong Liu
 Working Group: MBONE Deployment (mboned)
 With Segment Routing (SR) architecture, a unicast flow can be source- routed through an SR network following an explicit path specified in the packet, w/o the need for per-flow state in the network. As a result, the otherwise needed protocols to signal the per-flow unicast state can also be removed from the network. In the case of multicast, traffic can be either source-routed or non-source-routed, and this document discusses non-sourced-routed options for multicast in an SR network with either MPLS or IPv6/SRv6 data plane.

Charter for Working Group

The Multicast Backbone Deployment Working Group (MBONED WG) is a forum for coordinating the deployment, engineering, and operation of multicast routing protocols and procedures in the global Internet, inter-domain and single domain. The MBONED WG activity will include the following work areas:

  • Receive regular reports on the current state of the deployment of multicast technology.

  • Document deployment of multicast routing in the global Internet.

  • Capture the operational experience of those who have deployed and are deploying various multicast technologies.

  • Identify, develop, and maintain mechanisms to address transport-layer and security-related gaps that hinder broader multicast deployment.

  • Develop mechanisms and procedures for sharing operational information to aid in operation of the multicast backbones and interconnects.

  • Investigate and define tools and mechanisms applicable to multicast deployment in emerging environments (e.g., decentralized systems and overlay networks) or other contexts where conventional deployment models may not suffice.

  • Specify and maintain tools, protocols, and procedures that assist with multicast administration, diagnostics, troubleshooting, and interoperability between native and non-native multicast environments (e.g., Mtrace and Automatic Multicast Tunneling (AMT)).

  • Develop and maintain data models and other automation-enabling components related to the operation of multicast services.

Development of routing protocols, forwarding-plane solutions and extensions, and group membership protocols is out of scope. The MBONED WG may assist in review of documents in other working groups responsible for such protocols (e.g., PIM, BIER, BESS, and LISP). Likewise, the MBONED WG will solicit inputs for its chartered work and assist in review for relevant work in other groups (e.g., MOPS, TSVWG, CCWG, NETCONF, and SAAG).
