ROUTE OPTIMIZATION FOR INTRA- OR INTER-DATA CENTERS COMMUNICATION

摘要

A method for re-routing communication, between two software entities, intra- or inter-data center networks (DCNs). The method includes receiving (900) at a route optimizer entity (230) a list (750) of software entity pairs that experience performance degradation, wherein the list (750) is sent by a data center controller (202/220) of the DCNs, receiving (902) at the route optimizer entity (230) a topology of the DCNs and routing information associated with the software entity pairs; calculating (904), in a path computation element (232), a new route for a first software entity pair of the software entity pairs from the list (750), based on the topology and routing; information of the software entity pairs, to alleviate the performance degradation; and sending (906) the new route to the data center controller (202/220) for modifying an existing route of the first software entity pair.
