Abstract
A network includes a plurality of endpoint routers and intermediate routers. When a new data stream is detected at any endpoint router, the first packet is sent to a virtual routing server with knowledge of the entire network topology. Based on the topology, current usage, and historical usage, the virtual routing server determined a path for the data stream and begins to update the routing tables of the intermediate routers to reflect the determined path. Until the update is complete, all packets in the data stream are routed first to the virtual routing server and then to their destination. Once the update is complete, packets in the data stream are routed directly along the determined path.
