1. A network device comprising:

  • plurality of execution units;

    plurality of session initiation protocol (SIP) processes comprising;

    a SIP transport process;

    a SIP location server process; and

    a plurality of SIP core processes,the SIP transport process executing on a first one of the execution units and communicating with at least a portion of the SIP core processes through an inter-processor communication mechanism,the SIP location server Process executing on a second one of the execution units and communicating with the at least a portion of the SIP core processes through the inter-processor communication mechanism,wherein the SIP transport process receives an ingress SIP packet, transforms the ingress SIP packet to a corresponding message, and delivers the corresponding message to one of the plurality of SIP core processes; and

    wherein the one of the plurality of SIP core processes modifies the corresponding message to include a next hop destination and delivers the modified message to the SIP transport process; and

    wherein the SIP transport process transforms the modified message into an egress SIP packet for transmission outside the network device,each of the SIP core processes executing on a different remaining one of the execution units.
