Abstract:
1. A method of swapping a bandwidth reservation comprising: receiving a request for a first communication session between a first end point in a first network and a second endpoint in a second network, the first communication session routed through a first gateway in the first network and a second gateway in the second network; in response to receiving a request for the first communication session, requesting a bandwidth reservation for the first communication session corresponding to the entire media path between the first end point in the first network and the second endpoint in the second network through the first gateway and the second gateway; prior to establishing the first communication session, receiving a confirmation of the requested bandwidth reservation, the confirmation corresponding to an indication that requested bandwidth has been reserved along the entire media path between the first endpoint in the first network and the second endpoint in the second network through the first gateway and the second gateway; storing session information indicating that the bandwidth reservation corresponds to the first communication session; receiving a request for a second communication session between the first endpoint and a third endpoint, the third endpoint located in the second network, the second communication session routed through the first gateway and the second gateway; determining that the second communication session can use the bandwidth reservation corresponding to the first communication session while the first communication session is in progress; modifying the session information to indicate that the bandwidth reservation corresponds to the second communication session; and requesting a swap of the bandwidth reservation from the first communication session to the second communication session.
