Protocol Independent Multicast (pim) ------------------------------------ Charter Last Modified: 2007-04-02 Current Status: Active Working Group Chair(s): Tom Pusateri <pusateri@bangj.com> Mike McBride <mmcbride@cisco.com> Routing Area Director(s): Ross Callon <rcallon@juniper.net> David Ward <dward@cisco.com> Routing Area Advisor: David Ward <dward@cisco.com> Mailing Lists: General Discussion:pim@ietf.org To Subscribe: http://www1.ietf.org/mailman/listinfo/pim/ Archive: http://www.ietf.org/mail-archive/web/pim/index.html Description of Working Group: The Protocol Independent Multicast (PIM) Working Group is chartered to standardize and promote the Protocol Independent Multicast Version 2 (PIMv2), Sparse Mode and Dense Mode, as a scalable, efficient and robust multicast routing protocol, capable of supporting thousands of groups, different types of multicast applications, and all major underlying layer-2 subnetwork technologies. The working group will decide if there is a need for any follow on work or version 3 of the protocol. This working group will act as a consultant to any PIM-over-Foo proposals, including but not limited to PIM-over-ATM, using PIM for multiprotocol label switching, and PIM-over-UDLR links. Documents: 1) PIM-SM v2 specification (standards track) This document is a specification for Sparse Mode Protocol Independent Multicast. 2) PIM-DM v2 speficication (standards track) This document is a specification for Dense Mode Protocol Independent Multicast. 3) PIM MIB (standards track) This document contains the MIB definitions for PIMv2. 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. Submision 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.
