Abstract
In general, techniques are described for performing decentralized packet dispatch. A network device comprising one or more service processing units (SPUs) and an interface may implement the techniques. The interface receives a packet associated with a session and selects a first one of SPUs to dispatch the packet based on first information extracted from the packet. The first one of the SPUs dispatches the packet to a second one of the SPUs based on second information extracted from the packet. The second one of the SPUs performs first pass processing to configure the network security device to perform fast path processing of the packet such that second one of the SPUs applies one or more services to the packet and subsequent packets associated with the same session without application of services to the packets by the first one of the service processing units.
