    Multi-party Chat Using the Message Session Relay Protocol (MSRP)
                       draft-ietf-simple-chat-18

Abstract

   The Message Session Relay Protocol (MSRP) defines a mechanism for
   sending instant messages within a peer-to-peer session, negotiated
   using the Session Initiation Protocol (SIP) and the Session
   Description Protocol (SDP).  This document defines the necessary
   tools for establishing multi-party chat sessions, or chat rooms,
   using MSRP.
