A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Media Server Control Working Group of the IETF.

	Title           : Media Resource Brokering

The MediaCtrl work group in the IETF has proposed an architecture for
controlling media services.  The Session Initiation Protocol (SIP) is
used as the signalling protocol which provides many inherent
capabilities for message routing.  In addition to such signalling
properties, a need exists for intelligent, application level media
service selection based on non-static signalling properties.  This is
especially true when considered in conjunction with deployment
architectures that include 1:M and M:N combinations of Application
Servers and Media Servers.  This document introduces a Media Resource
Broker (MRB) entity which manages the availability of Media Servers
and the media resource demands of Application Servers.  The document
includes potential deployment options for an MRB and appropriate
interfaces to Application Servers and Media Servers.
