Abstract
Methods and systems for providing voice over IP traffic engineering and path resilience using a network-aware media gateway are provided. In a media gateway, voice over IP hosts are assigned a first set of IP addresses. Network interfaces in the media gateway are assigned a second set of IP addresses that differ from the first set of IP addresses. Per-interface routers advertise reachability information from at least one of the voice over IP hosts via multiple interfaces and participate in network routing protocols to generate per interface routing tables. Voice over IP path lists may be generated based on the per interface routing tables. Internal costs may be assigned to the associations between the voice over IP hosts and the interfaces based on traffic engineering criteria.
