Abstract
This document defines the Session Description Protocol, SDP. SDP is
intended for describing multimedia sessions for the purposes of
session announcement, session invitation, and other forms of
multimedia session initiation.
This document is a product of the Multiparty Multimedia Session
Control (MMUSIC) working group of the Internet Engineering Task
Force. Comments are solicited and should be addressed to the working

1. Introduction
On the Internet multicast backbone (Mbone), a session directory tool
is used to advertise multimedia conferences and communicate the
conference addresses and conference tool-specific information
necessary for participation. This document defines a session
description protocol for this purpose, and for general real-time
multimedia session description purposes. This memo does not describe
multicast address allocation or the distribution of SDP messages in
detail. These are described in accompanying memos. SDP is not
intended for negotiation of media encodings.
