Abstract:
A neural fuzzy connection admission controller in a node of an Asynchronous Transfer Mode (ATM) communication network comprising:first layer nodes each for inputting and storing three parameter inputs of an available capacity C.sub.a, a traffic load adjustment parameter y, and a cell loss ratio P.sub.l ;second layer nodes fully interconnected with said first layer nodes each for generating fuzzified result signals indicating said available capacity of the system after accepting a new connection, said traffic load adjustment parameter y, and said cell loss ration P.sub.l ;third layer nodes fully interconnected with said second layer nodes each representing a fuzzy control rule for training said fuzzified result and performing precondition matchings of each of said fuzzy control rule to generate fuzzy control signals;fourth layer nodes fully interconnected with said third layer nodes each having two operation modes for executing a down-up operation and a up-down operation, said down-up operation performing a consequence matching of each of said fuzzy control rule for the links, and said up-down operation performing fuzzy OR operation to integrate the fired strength of a fuzzy control rule; andfifth layer nodes consisting of down-up nodes and up-down nodes, each down-up node and its links defuzzifying input data to generate a decision signal Z, and said up-down nodes for training a desired decision signal Z, and said desired decision signal Z is dynamically updated in response to a performance feedback P.sub.l.
