A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Audio/Video Transport Working Group of the IETF. Title : Requirements for Header Compression over MPLS Author(s) : J. Ash, et al. Filename : draft-ietf-avt-hc-mpls-reqs-02.txt Pages : 9 Date : 2004-6-10 VoIP typically uses the encapsulation voice/RTP/UDP/IP. When MPLS labels are added, this becomes voice/RTP/UDP/IP/MPLS-labels, where, for example, the packet header is at least 48 bytes, while the voice payload is often no more than 30 bytes. Header compression can significantly reduce the overhead through various compression mechanisms, such as enhanced compressed RTP (ECRTP) and robust header compression (ROHC). We consider using MPLS to route compressed packets over an MPLS LSP without compression/decompression cycles at each router. This approach can increase the bandwidth efficiency as well as processing scalability of the maximum number of simultaneous flows that use header compression at each router. In the draft we give a problem statement, goals and requirements, and an example scenario.

Login with the username "anonymous" and a password of your e-mail address. After logging in, type "cd internet-drafts" and then "get draft-ietf-avt-hc-mpls-reqs-02.txt". A list of Internet-Drafts directories can be found in http://www.ietf.org/shadow.html or ftp://ftp.ietf.org/ietf/1shadow-sites.txt Internet-Drafts can also be obtained by e-mail. Send a message to: mailserv@ietf.org. In the body type: "FILE /internet-drafts/draft-ietf-avt-hc-mpls-reqs-02.txt". NOTE: The mail server at ietf.org can return the document in MIME-encoded form by using the "mpack" utility. To use this feature, insert the command "ENCODING mime" before the "FILE" command. To decode the response(s), you will need "munpack" or a MIME-compliant mail reader. Different MIME-compliant mail readers exhibit different behavior, especially when dealing with "multipart" MIME messages (i.e. documents which have been split up into multiple messages), so check your local documentation on how to manipulate these messages. Below is the data which will enable a MIME compliant mail reader implementation to automatically retrieve the ASCII version of the Internet-Draft.
