The Binary Floor Control Protocol (BFCP)
draft-ietf-bfcpbis-rfc4582bis-09
Abstract
Floor control is a means to manage joint or exclusive access to
shared resources in a (multiparty) conferencing environment.
Thereby, floor control complements other functions -- such as
conference and media session setup, conference policy manipulation,
and media control -- that are realized by other protocols.
This document specifies the Binary Floor Control Protocol (BFCP).
BFCP is used between floor participants and floor control servers,
and between floor chairs (i.e., moderators) and floor control
servers.
This document obsoletes RFC 4582. Changes from RFC 4582 are
summarized in Section 16.
