Media stream management
First Claim
1. A method for managing at least one media stream from a media source to a media destination, said media stream passing through at least one network, comprising the steps of:
- providing a media manager for managing said media stream and said at least one network and for performing at least one of a plurality of management functions, including bandwidth management, media hairpin detection, media path control, equal access, or preventing media backhauling, wherein the media manager has an interface path to a session layer protocol proxy and an interface path to a media gateway, the media gateway being linked to either the media source or media destination;
sending, by the session layer protocol proxy, a media stream update message to the media manager to establish a plurality of media stream information types for the media stream, wherein the media stream update message is sent in response to the session layer protocol proxy receiving a SIP invite message;
storing in said media manager at least one of the plurality of media stream information types, the media stream information types including media routing, receive transport address, routed receive transport address, source network, destination network, media stream identifier, or bandwidth of the media stream for a time period during which said at least one media stream exists in said at least one network;
said media manager using at least one of said stored information types for performing at least one of said management functions, wherein the media manager is configured to perform bandwidth management by calculating an aggregated bandwidth value for said at least one network by totaling values of said bandwidth information types of said at least one media stream and any additional media streams passing through said at least one network and using the aggregated bandwidth value in determining whether to disallow setup of said at least one media stream, wherein in response to determining to allow setup of said at least one media stream, sending a media stream OK message from the media manager to the session layer protocol proxy.

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.
