The IESG has approved the following document: - 'Selectively Reliable Multicast Protocol (SRMP) ' <draft-pullen-srmp-06.txt> as an Experimental RFC This document has been reviewed in the IETF but is not the product of an IETF Working Group. The IESG contact person is Allison Mankin. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-pullen-srmp-06.txt Technical Summary The Selectively Reliable Multicast Protocol (SRMP) is a congestion- aware transport protocol over UDP, intended to deliver a mix of reliable and best-effort messages in an any-to-any multicast environment, where the best- effort traffic occurs in significantly greater volume than the reliable traffic and therefore can be used to carry sequence numbers of reliable messages for loss detection. SRMP is intended for use in a distributed simulation application environment, where only the latest value of reliable transmission for any particular data identifier requires delivery. Like all multicast transport protocols with reliability, the IETF publishes SRMP as an Experimental specification first, in order to assess the impact of the RFC, and determine after a year or two whether the congestion avoidance and control are effective, prior to considering standardization. Working Group Summary This protocol was developed by individual contributors to IETF, but it received some discussion and review by the Reliable Multicast Working Group, which determined that its any-to-any multicast basis was outside the RMT charter, but that the basic approach was simple and did not raise objections. The sponsoring AD reviewed comparable work from ISO JTC-1 SC-6 and believes this work is well-distinguished because of its mixed reliability service offering. Protocol Quality The protocol has been implemented and tested by several groups, and there is a publicly available simulation for it as well. A careful review against the RFC 2357 requirements was performed by the sponsoring Area Director, Allison Mankin. _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www1.ietf.org/mailman/listinfo/ietf-announce
