[pim] PIM WG recharter

[Mike McBride <[e-mail]>]

Hello all,

Stig and I hope you had a wonderful start to your new year. 

We hope to have a wonderful start for pim in 2015 as well. We've discussed rechartering for the past year and Stig and I have made a first pass below. Thanks to Bill Atwood and Lucy Yong in providing edits to this draft. Please review and comment on this proposed new charter and wg renaming. Through the MCAST WG (Protocols) and the MBONED WG (Operations) we should be able to more effectively standardize multicast technologies.

Thanks,
mike

Charter for Working Group

The standardization of PIM was completed with RFC 4601 within the PIM WG. The MCAST WG has determined there is additional work to be accomplished and is chartered to standardize extensions to RFC 4601 - Protocol Independent Multicast Version 2 - Sparse Mode, along with extensions to PIM-SSM and PIM-BIDIR. These multicast extensions will involve reliability, resiliency, scalability, management, mobility and security. The MCAST WG will continue to work on developing the IGMP/MLD protocols as needed to achieve the robustness needed, particularly in mobile environments.

As other WGs determine that support for multicast in their domains requires multicast specific extensions to PIM, IGMP/MLD, IGPs, or other yet to be invented multicast specific protocols, then such extensions should be developed within the MCAST WG. Additional work on existing PIM-BIDIR, BSR and SSM drafts may also be necessary by the WG as these drafts progress through Standards Track.

The working group has produced MIB modules for PIM in RFC 5060 and RFC 5240. The MCAST WG will work on proposals that update or extend the existing MIB modules and will develop YANG modules for multicast protocols.

The MCAST WG will further enhance RFC4601 as an even more scalable, efficient and robust multicast routing protocol, which is capable of supporting thousands of groups, different types of multicast applications, and all major underlying layer-2 subnetwork technologies. We will accomplish these enhancements by submitting drafts, to the IESG, involving reliable multicast, pim join attributes and authentication.

There is a significant number of errata that need to be addressed in order to advance RFC4601 to Internet Standard. The MCAST WG will correct the errata and update RFC4601.

The working group will initiate a new re-chartering effort if it is determined that a Version 3 of PIM is required.

Charter for Working Group

The Protocol Independent Multicast (PIM) Working Group has completed
the standardization of PIM with RFC 4601. The WG has determined there
is additional work to be accomplished and is chartered to standardize
extensions to RFC 4601 - Protocol Independent Multicast Version 2 -
Sparse Mode. These PIM extensions will involve reliability, resiliency,
scalability, management, and security.

If L2VPN or L3VPN WGs determine that support for multicast in L2VPNs
and/or L3VPNs requires extensions to PIM, then such extensions will be
developed within the PIM WG.

Additional work on the PIM-BIDIR and BSR drafts may also be necessary
by the WG as these drafts progress through Standards Track.

The working group has produced MIB modules for PIM in RFC 5060 and
RFC 5240. The working group currently has no plans to do further work
on management for PIM. If proposals are brought forward to update or
extend the existing MIB modules or to develop YANG modules, the working
group will be rechartered.

The PIM WG will further enhance RFC4601 as an even more scalable,
efficient and robust multicast routing protocol, which is capable of
supporting thousands of groups, different types of multicast
applications, and all major underlying layer-2 subnetwork technologies.
We will accomplish these enhancements by submitting drafts, to the
IESG, involving reliable pim, pim join attributes and pim
authentication.

The working group primarily works on extensions to PIM, but may take on
work related to IGMP/MLD.

There is a significant number of errata that need to be addressed in
order to advance RFC4601 to Draft Standard. The PIM WG will correct the
errata, as necessary, and update RFC4601.

The working group will initiate a new re-chartering effort if it is
determined that a Version 3 of PIM is required.
