Title : Using Partial Offers and Partial Answers in a
Multimedia Session

Abstract:
Whenever two hosts have the ability to set up and control a session
on a peer-to-peer basis, situations can arise in which both parties
attempt to change session parameters "at the same time," such that
the session control messages cross on the wire. When this happens,
implementations need to invoke extraordinary procedures to return the
shared state of the session to a common view between the endpoints.
For real-time communications, these session control messages are
typically exchanged using the session description protocol (SDP),
using an Offer/Answer model. This document expands the offer/answer
model to include the ability to exchange information relating to
discrete media streams within the session. By reducing the amount of
session data, the frequency of session state conflicts can be
reduced; and, for certain types of operations, conflicts can be
eliminated altogether.
This document updates RFC 3264.
