Abstract
A telecommunications network (10) includes a plurality of telecommunication switches (12). Each telecommunication switch (12) includes a set of processors (14) in order to provide a distributed architecture. A network processor (16) periodically communicates with each set of processors (14) of each telecommunication switch (12) to collect various switch and network information and respond with routing recommendations. These routing recommendations are provided in response to a switch utilization index determined for each telecommunication switch (12). The switch utilization index provides an up to date picture of the in service trunks and a realistic figure of the global load on the processors (14). The switch occupancy index is based on trunks, call attempts, time, and switch type and is defined as the ratio of new call arrival rate to the maximum call arrival rate for a dynamically controlled routing processing cycle.
