During past few years, Fuzzy Logic Controllers (FLCs) have found many applications in different area of engineering. In this paper we present the applications of FLC in the traffic management of different communication network technology including Asynchronous Transfer Network (ATM) and Internet Protocol (IP). Different fuzzy controllers will be proposed for different traffic management mechanisms including buffer management, Active Queue Management (AQM), traffic policing, traffic metering, scheduling, Usage Parameter Control (UPC) and Call Admission Control (CAC). Based on simulation results, it can be seen that all proposed fuzzy controllers demonstrate better performance in comparison with traditional mechanisms.
