In a variety of conferencing scenarios, a local communication channel
is desirable for conference-related information exchange between
co-located but otherwise independent application entities, for example
those taking part in application sessions that belong to the same
conference. In loosely coupled conferences such a mechanism allows
for coordination of applications entities to e.g. implement
synchronization between media streams or to configure entities
without user interaction. It can also be used to implement tightly
coupled conferences enabling a conference controller to enforce
conference wide control within a end system.
The local conference Message Bus (Mbus)
provides a means to achieve
the necessary amount of coordination between co-located conferencing
applications for virtually any type of conference as postulated in
a companion requirements draft. The Message Bus
comprises two logically distinct parts: a message transport and
addressing infrastructure and a set of common as well as media tool
specific messages. This document deals with message addressing,
transport, and security issues and defines the message syntax for the
Mbus. It does not define application oriented semantics and
procedures for using the message bus. The common procedures for Mbus
operation as well as the common set of application/media specific
messages are introduced in
a companion Internet draft.
