System and method for enhanced media brokering in VoIP network

摘要

Mechanisms are provided to broker and control media resources. In particular, solutions are described which broker and control a media request sent from an application server. The media request is received at a device capable of brokering and controlling the media request such that a media server capable of providing the request may be selected. A screening functionality is also presented such that an optimal media server may be selected based on a comparison between information contained in an incoming media request and information contained in a previously provisioned Service Level Agreement; such information may relate to media service and capacity information. Further, solutions are presented to support providing media services in heterogeneous environments where an application server and a media server may communication using different media control protocols.
