From: The IESG To: IETF-Announce Message-Id: Date: Thu, 10 Mar 2005 15:10:54 -0500 Cc: avt chair , avt chair , Internet Architecture Board , avt mailing list , RFC Editor Subject: Protocol Action: 'Tunneling Multiplexed Compressed RTP ('TCRTP')' to BCP The IESG has approved the following document: - 'Tunneling Multiplexed Compressed RTP ('TCRTP') ' as a BCP This document is the product of the Audio/Video Transport Working Group. The IESG contact persons are Allison Mankin and Jon Peterson. Technical Summary This document describes a Best Common Practice supported by the AVT Working Group of using Enhanced Compressed RTP (ECRTP, RFC 3545), PPP-MUX (RFC 3153) over L2TP (RFC 2661)). This usage is the current approach for multiplexing RTP. The rationale for tunneling and compressing it is that even in what are usually thought of as the well-provisioned environments of wide area carriers, there are there are systems-level reasons to use compressed RTP. ECRTP is used at this time for tunnels in which reordering can occur; though ROHC (RFC 3095) would produce higher compression, there are considerations in development to best handle reordering in ROHC. Working Group Summary The working group supported the advancement of this document once ECRTP was complete. Protocol Quality Allison Mankin reviewed for the IESG. The IESG had many comments in cross-area review.
