Abstract:
A network resource reservation system for dynamically rerouting data packets to optimize bandwidth in a communications network during call set-up time and during the duration of a call, comprising:a network control unit for establishing an initial communications route between a source node and an end node for carrying the data;a reroute control unit for establishing an alternate communications route when said alternate communications route is determined to be more optimal than said initial communications route, said determination being made periodically while a communication along said initial communications route is ongoing, wherein said determination may be made more than once during said communication, wherein more than one alternate route may be established during said communication, responsive to said determining; anda packet reordering unit for enabling the real-time data packets to travel to said end node in the proper sequence after said reroute control unit establishes said alternate communications route.
