The Protocols for IP Multicast (PIM) working group, is chartered to work
on multiple IP multicast protocols.  The Working Group is responsible for the
maintenance of PIM, IGMP, and MLD.

The Working Group will work on the following specific items:

1) Management:  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.

2) Improve PIM authentication.

3) Improve and Extend PIM Join Attributes to support different types of
multicast applications.

4) Optimization approaches for IGMP and MLD to adapt to link conditions in
wireless and mobile networks and be more robust to packet loss.

Additional work items may be added with a recharter.

The WG should discuss and develop new ideas related to multicast protocols and
distribution of multicast related information.

The WG is expected to use its extensive multicast knowledge to actively review
and participate in WG Last Calls with multicast work that occurs in other WGs,
such as MBONED, LISP, MPLS, BESS, ROLL, and BIER. The WG should investigate any
extensions needed to support other work and, if additional work is required,
the WG may be rechartered to accomplish the specific extensions.
