As IP-based multimedia infrastructures mature, the complexity and demands from deployments increase. Such complexity will result in a wide variety of capabilities from a range of vendors that should all be interoperable using the architecture and protocols produced by the MediaCtrl working group. It should be possible for a controlling entity to be assisted in Media Server selection so that the most appropriate resource is selected for a particular operation. The importance increases when one introduces a flexible level of deployment scenarios, as specified in RFC 5167 [RFC5167] and RFC 5567 [RFC5567]. These documents make statements like "it should be possible to have a many-to-many relationship between Application Servers and Media Servers that use this protocol". This leads to the following deployment architectures being possible when considering media resources, to provide what can be effectively described as media resource brokering.

                         Media Resource Brokering


   The MediaCtrl working group in the IETF has proposed an architecture    for controlling media services.  The Session Initiation Protocol    (SIP) is used as the signaling protocol that provides many inherent    capabilities for message routing.  In addition to such signaling    properties, a need exists for intelligent, application-level media    service selection based on non-static signaling 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.
