METHOD OF OPTIMIZING ROUTING DECISIONS OVER MULTIPLE PARAMETERS UTILIZING FUZZY LOGIC

A method of determining the optimum route from a source to a destination node in an ATM network utilizing fuzzy logic processing to determine the optimum route based on a set metrics that may or may not be related to each other. The invention utilizes well known fuzzy logic techniques to perform optimization and calculations based on intuitive rules rather then complex mathematical solutions. The method of the invention can be applied to routing algorithms to determine the optimum route when it is desired to optimize the route based on a large number of metrics, attributes and/or parameters. The fuzzy logic processing is divided into two phases each having its own set of rules that the input data is applied against. Fuzzy logic processing is performed for all candidate routes wherein the route chosen is the one having a maximum link quality.
