Abstract:
A system of one embodiment that provides stateless symmetric forwarding of packets in a computer network. The system includes a memory and a processor. The system is operable to determine a cluster state of a plurality of border routers in a cluster. The system is operable to communicate the cluster state to at least one branch node in the computer network. The system is operable to generate a network level consistent hash based on the cluster state. The system is operable to route a first packet through a first border router of the plurality of border routers in the cluster using the network level consistent hash. After the first packet is sent through a first border router, the system is further operable to route a second packet through the first border router of the plurality of border routers in the cluster using the network level consistent hash.
