  • Scalable ATM signaling message processing based on per session dispatch
    Patent number: 6072799
    Abstract: A new method of processing Asynchronous Transfer Mode (ATM) signaling messages is described wherein a plurality of computing units (CUs), each running signaling processing software, collectively provide signaling processing services for all the ports of a switch. As more ports, and more cards, are added to a switch, CUs can be incrementally added to support additional traffic. More significantly, in order to optimize the utilization rates of the plurality of CUs, the method provides for dynamic load-sharing of signaling traffic between CUs, such that a CU is allocated not on a per port basis, but on a per switched virtual circuit (SVC) session basis.
