Abstract

In a method and system for managing at least one media stream from a media source to a media destination, where the media stream passes through at least one network, providing a media manager for managing the media stream and the at least one network for performing at least one of the management functions bandwidth management, media hairpin detection, media path control, equal access or preventing media backhauling. In the media manager at least one of the media stream information types media routing, receive transport address, routed receive transport address, source network, destination network, media stream identifier, or bandwidth of the media stream is stored for a time period during which the media stream exists in the at least one network. The media manager uses at least one of the stored information types for performing at least one of the management functions.

21. A method of claim 1 wherein a session server with which said media manager communicates is in an ASP network and said media manager is in an ISP network.

22. A method of claim 1 wherein a session server and said media manager in communication with said session server are in a common network.

23. A method of claim 22 wherein a media gateway is also provided in said common network with said media manager.

24. A method of claim 1 wherein a session server is provided in communication with said media manager, and said session server sends a media stream update message to said media manager, and said media manager responds with a media stream OK message depending upon how said media manager is managing at least one of said management functions.
