A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Multiparty Multimedia Session Control Working Group of the IETF.
Title : An Offer/Answer Model with SDP
Author(s) : J. Rosenberg, H. Schulzrinne
Filename : draft-ietf-mmusic-sdp-offer-answer-02.txt
Pages : 25
Date : 28-Feb-02
This document defines a mechanism by which two entities can make use
of SDP to arrive at a common view of a multimedia session between
them. In the model, one participant offers the other a description of
the desired session from their perspective, and the other participant
answers with the desired session from their perspective. This
offer/answer model is most useful in unicast sessions where
information from both participants is needed for the complete view of
the session. The offer/answer model is used by protocols like the
Session Initiation Protocol (SIP).

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.
