1. A computer-readable storage medium comprising instructions to cause a computing device to perform a method for assigning network flow processing tasks within a cluster comprising a plurality of communicatively coupled computing devices, the method comprising:

  • maintaining a flow assignment data structure comprising mappings between network flows and cluster computing devices assigned thereto;

    identifying a network flow for processing by the cluster;

    determining whether the network flow is already being processed by a cluster computing device using the flow assignment data structure;

    assigning the network flow to a selected one of the cluster computing devices when the flow has not been assigned to a cluster computing device; and

    updating the flow assignment data structure to map the network flow to the assigned cluster computing device.
