Protocol Independent Multicast (pim) ------------------------------------ Charter Last Modified: 2007-09-26 Current Status: Active Working Group Chair(s): Mike McBride Stig Venaas Routing Area Director(s): Ross Callon David Ward Routing Area Advisor: David Ward 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. Done Ratify new WG charter and milestones Dec 2007 Submit the BSR spec as a Proposed Standard to the IESG Dec 2007 Submit the BSR MIB as a Proposed Standard to the IESG Mar 2008 Submit a more reliable pim solution (refresh reduction) to the IESG Mar 2008 Submit a generic TLV PIM Join Attribute PS draft to the IESG Mar 2008 Submit RPF Vector (use of PIM Join Attribute) as PS to the IESG Mar 2008 Submit a way to authenticate PIM link local messages as PS to the IESG Mar 2008 Submit an Informational PIM last hop threats document to the IESG Internet-Drafts: Posted Revised I-D Title ------ ------- -------------------------------------------- Feb 2005 Nov 2007 The RPF Vector TLV Oct 2005 May 2007 Format for using TLVs in PIM messages Aug 2006 Oct 2007 PIM Bootstrap Router MIB Oct 2006 Nov 2007 Authentication and Confidentiality in PIM-SM Link-local Messages Oct 2006 Oct 2007 Host Threats to Protocol Independent Multicast (PIM) Request For Comments: RFC Stat Published Title ------- -- ----------- ------------------------------------ RFC3973 E Jan 2005 Protocol Independent Multicast - Dense Mode (PIM-DM): Protocol Specification (Revised) RFC4610 PS Aug 2006 Anycast-RP Using Protocol Independent Multicast (PIM) RFC4601 PS Aug 2006 Protocol Independent Multicast - Sparse Mode (PIM-SM): Protocol Specification (Revised) RFC4602 I Aug 2006 Protocol Independent Multicast - Sparse Mode (PIM-SM) IETF Proposed Standard Requirements Analysis RFC5015 PS Oct 2007 Bi-directional Protocol Independent Multicast (BIDIR-PIM) RFC5060 PS Jan 2008 Protocol Independent Multicast MIB RFC5059 PS Jan 2008 Bootstrap Router (BSR) Mechanism for Protocol Independent Multicast (PIM)
