SYSTEM AND METHOD FOR PATH COMPUTATION SERVICE FOR A SERVICE AWARE VIRTUAL TOPOLOGY OVER A WIDE AREA NETWORK

Abstract: systems and methods for generating routing tables and providing these tables to routers in a network for use in routing data to various destination routers. one embodiment comprises an apparatus that includes a centralized controller for a network. the centralized controller is adapted to receive link metrics for a plurality of links between routers in a wan. for each pair of routers, the centralized controller determines the paths between the router pair, determines suitability metrics for each path, wherein each metric is specific to a corresponding data type, and selects, for each data type, a corresponding subset of the paths between the router pair based at least in part on the suitability metrics for the data type. the centralized controller then transmits, to each of the routers in the wan, the selected subsets of the paths for the corresponding router.
