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).
