The Protocol Independent Multicast (pim) working group in the Routing Area of the IETF has been rechartered. For additional information, please contact the Area Directors or the working group Chairs. Protocol Independent Multicast (pim) ----------------------------------- Current Status: Active Working Group Chairs: Mike McBride <mmcbride@cisco.com> Stig Venaas <stig@venaas.com> Routing Area Directors: Stewart Bryant <stbryant@cisco.com> Adrian Farrel <adrian@olddog.co.uk> Routing Area Advisor: Adrian Farrel <adrian@olddog.co.uk> Mailing Lists: General Discussion: pim@ietf.org To Subscribe: https://www.ietf.org/mailman/listinfo/pim/ Archive: http://www.ietf.org/mail-archive/web/pim/ Description of 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. Goals and Milestones: Done Hold the first Working Group meeting and discuss the charter and the state of progress on the chartered items. Done Update the PIM-DM version 2 Internet-draft. Go to WG last call. Submission to IESG for considerations as proposed standard. Done Resubmit the latest PIM-SM version 2 specification to IESG for consideration as a proposed standard RFC Done Submit PIM-SM Applicability Statements Done Submit PIMv2 MIB to IESG for consideration as proposed standard. Done Submit updated PIM-SM and PIM-DM internet-drafts, clarifying any inconsistencies or ambiguities in the previous drafts. Done Submit PIM-SM version 2 and PIM-DM version 2 specifications to IESG for consideration as Draft Standards. Done Submit PIMv2 MIB to IESG for consideration as draft standard. Done Ratify new WG charter and milestones Done Submit the BSR spec as a Proposed Standard to the IESG Done Submit the BSR MIB as a Proposed Standard to the IESG Done Submit a generic TLV PIM Join Attribute PS draft to the IESG Done Submit RPF Vector (use of PIM Join Attribute) as PS to the IESG Done Submit a way to authenticate PIM link local messages as PS to the IESG Done Submit an Informational PIM last hop threats document to the IESG Aug 2011 First WG version of udated RFC 4601 Aug 2011 Submit a more reliable PIM solution (refresh reduction) to the IESG Nov 2011 Submit a population count extension to PIM to the IESG Dec 2011 Submit update of RFC 4601 to IESG for advancement to Draft Standard _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
