A new Request for Comments is now available in online RFC libraries.
Title: An Offer/Answer Model with Session Description
Author(s): J. Rosenberg, H. Schulzrinne
Status: Standards Track
Date: June 2002
I-D Tag: draft-ietf-mmusic-sdp-offer-answer-02.txt
This document defines a mechanism by which two entities can make use
of the Session Description Protocol (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).
This document is a product of the Session Initiation Protocol Working
Group of the IETF.
This is now a Proposed Standard Protocol.
