The IESG has approved the following document: - 'Media Resource Brokering' (draft-ietf-mediactrl-mrb-19.txt) as Proposed Standard This document is the product of the Media Server Control Working Group. The IESG contact persons are Robert Sparks and Gonzalo Camarillo. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-mediactrl-mrb/ Technical Summary 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. Working Group Summary The working group consensus on this document is solid. Two WGLCs were held, one after the initial consensus on the document, and one after extensive review and implementation experience dictated a number of small improvements to the protocol and its description. Document Quality The protocol described in this document has been implemented by several major vendors. The description has also been carefully reviewed by someone not involved in its writing or implementation. Personnel Dale Worley is the document's shepherd. Robert Sparks is the responsible AD.
