All, Please review and comment on the updated version of 'Protocol Extensions for ECRTP over MPLS' http://www.ietf.org/internet-drafts/draft-ash-avt-ecrtp-over-mpls-protocol-01.txt. The protocol extensions enable the use of MPLS to route enhanced compressed RTP (ECRTP) compressed packets over an MPLS LSP without compression/decompression cycles at each router. The proposed extensions are based on the requirements documented in 'Requirements for Header Compression over MPLS' http://www.ietf.org/internet-drafts/draft-ietf-avt-hc-mpls-reqs-00.txt. Comments received on the 00 version have been incorporated, in particular, those comments discussed in: http://www.ietf.org/mail-archive/working-groups/avt/current/msg03404.html http://www.ietf.org/mail-archive/working-groups/avt/current/msg03412.html http://www.ietf.org/mail-archive/working-groups/avt/current/msg03501.html http://www.ietf.org/mail-archive/working-groups/avt/current/msg03502.html Thanks, Jerry -----Original Message----- From: i-d-announce-admin@ietf.org [mailto:i-d-announce-admin@ietf.org]On Behalf Of Internet-Drafts@ietf.org Sent: Monday, May 03, 2004 3:54 PM To: i-d-announce@ietf.org Subject: I-D ACTION:draft-ash-avt-ecrtp-over-mpls-protocol-01.txt A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : Protocol Extensions for ECRTP over MPLS Author(s) : J. Ash, et al. Filename : draft-ash-avt-ecrtp-over-mpls-protocol-01.txt Pages : 0 Date : 2004-5-3 VoIP typically uses the encapsulation voice/RTP/UDP/IP. When MPLS labels are added, this becomes voice/RTP/UDP/IP/MPLS-labels. For an MPLS VPN, the packet header is at least 48 bytes, while the voice payload is often no more than 30 bytes, for example. Header compression can significantly reduce the overhead through various compression mechanisms, such as enhanced compressed RTP (ECRTP). We consider using MPLS to route ECRTP compressed packets over an MPLS LSP without compression/decompression cycles at each router. Such an ECRTP over MPLS capability can increase the bandwidth efficiency as well as processing scalability of the maximum number of simultaneous compressed flows that use header compression at each router. In this draft we propose to use RSVP-TE extensions to signal the header compression context and other control messages between the ingress and egress LSR. We re-use the methods in ECRTP to determine the context.
