  • Internal routing method for load balancing
    Patent number: 5271003
    Abstract: An internal routing method in an internal network for improving signaling message processing capability by balancing the workload among message handling processors (MHP) in common channel signaling system used in electronic exchanges. An internal routing algorithm is provided in the internal network to balance the workload among MHP's based on the characteristics of a circuit identification code (CIC). An identifying trunk circuit is uniformly distributed, and a load unbalancing factor is formulated approximately as a function of the number of failed MHP's as a worst case. With this approach, all MHP's are loaded almost equally regardless of the number of failed MHP's.
