Media Control Channel Framework
Abstract
This document describes a framework and protocol for application
deployment where the application programming logic and media
processing are distributed. This implies that application
programming logic can seamlessly gain access to appropriate resources
that are not co-located on the same physical network entity. The
framework uses the Session Initiation Protocol (SIP) to establish an
application-level control mechanism between application servers and
associated external servers such as media servers.
The motivation for the creation of this framework is to provide an
interface suitable to meet the requirements of a centralized
conference system, where the conference system can be distributed, as
defined by the XCON working group in the IETF. It is not, however,
limited to this scope.
