   Session Description Protocol (SDP) Format for Binary Floor Control
                        Protocol (BFCP) Streams
                    draft-ietf-bfcpbis-rfc4583bis-11

Abstract

   This document specifies how to describe Binary Floor Control Protocol
   (BFCP) streams in Session Description Protocol (SDP) descriptions.
   User agents using the offer/answer model to establish BFCP streams
   use this format in their offers and answers.

   This document obsoletes RFC 4583.  Changes from RFC 4583 are
   summarized in Section 14.
