Description of Working Group

     Existing inter-domain multicast routing protocols are not
     scalable to a large internetwork containing very large numbers
     of active wide-area groups.  The purpose of the IDMR Working
     Group, therefore, is to discuss proposed inter-domain multicast
     routing protocols, and put forward one (or a hybrid of several)
     as a Proposed Standard to the IESG.

     Several proposals have been made to date, including Core-Based
     Tree (CBT) multicasting, Core-Based Join (CBJ) multicasting,
     and Scalable Reverse Path Multicasting (SRPM). Some of the
     above have yet to be reviewed.


Goals and Milestones


Done       Post the Core Based Trees architecture as an Internet-Draft.

Done       Meet at IETF. All proposals must be submitted by this date.
           Discuss all proposals which have been submitted.

Dec 1993   Submit the Core Based Trees architecture Internet-Draft to
           the IESG to be published as an Informational RFC.

Done       Meet at IETF. Discuss security issues with respect to the
           proposed protocol(s).

Aug 1994   Post an Internet-Draft for a single protocol (which may be
           one of the proposals, or a combination of proposals), and an
           Internet-Draft serving as a protocol analysis document for that
           protocol (as required by RFC 1264).

Jan 1995   Submit the single protocol to the IESG as a Proposed
           Standard.

Mar 1995   Post an Internet-Draft for an IDMR MIB.

Jul 1995   Submit the IDMR MIB Internet-Draft to the IESG as a Proposed
           Standard.
