Abstract
A security device for processing network flows is described, including: one or more packet processors configured to receive incoming data packets associated with network flows where a packet processor is assigned as an owner of network flows and each packet processor processes data packets associated with flows for which it is the assigned owner; and a packet processing manager configured to assign ownership of network flows to the packet processors where the packet processing manager includes a global flow table containing global flow table entries mapping network flows to packet processor ownership assignments and a predict flow table containing predict flow entries mapping predicted network flows to packet processor ownership assignments. A predict flow entry includes a predict key and associated packet processor ownership assignment. The predict key includes multiple data fields identifying a predicted network flow where one or more of the data fields have a wildcard value.
