WG Review: Protocols for IP Multicast (pim)

The Protocols for IP Multicast (pim) WG in the Routing Area of the IETF is
undergoing rechartering. The IESG has not made any determination yet. The
following draft charter was submitted, and is provided for informational
purposes only. Please send your comments to the IESG mailing list
(iesg@ietf.org) by 2025-01-02.

Charter: https://datatracker.ietf.org/doc/charter-ietf-pim/

The Protocols for IP Multicast (PIM) Working Group is chartered to work on
the development of IP multicast protocols. This development includes the
maintenance, improvement and extension of the PIM, Internet Group Management
Protocol (IGMP) and Multicast Listener Discovery (MLD) protocols. The Working
Group will also work on the following items:

1) Altering existing procedures for improvement within environments not
optimal for multicast. 2) YANG models for PIM, IGMP, and MLD will be
developed for both configuration and operational states. If updates to
existing MIB modules are necessary, the WG may work on those. 3) Develop
Point-2-Multipoint (P2MP) Segment Routing protocols per agreement with the
SPRING WG. 4) Develop PIM extensions to improve multicast distribution trees
in Locator/ID Separation Protocol (LISP) environments. 5) Improve and extend
PIM Join Attributes to support different types of multicast applications. 6)
Develop multicast routing and group membership protocols to optimize and
improve network resilience. 7) Develop multicast group address allocation
protocols. 8) Create multicast protocol design experience documents.

New ideas related to multicast protocols, and distribution of multicast
related information, are welcome to be proposed to PIM. Adoption of such
work, beyond the scope of the above areas or items, will require a recharter.

The PIM WG mailing list, and WG meetings, are open to support review
discussions for multicast related work items from other WGs and RGs.
Currently, such adjacencies exist for work in MBONED, LISP, MPLS, BESS, ROLL
and BIER.
