An Offer/Answer Model for SDP

Status: Published as RFC 3264 in June 2002
Date of last update: June 2002
Authors: J. Rosenberg, H. Schulzrinne
Current Document: rfc3264.txt
Summary: 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).
