Design of a Fuzzy Usage Parameter Controller(FUPC) for ATM Networks

摘要

This paper presents the design of a fuzzy usage parameter controller (FUPC) for ATM (asynchronous transfer mode) networks. The usage parameter control (UPC) is here based on a dual leaky bucket (DLB) mechanism, with parameters of token generation rate and token pool size. In FUPC, we further employ parameters of token-change rate and interarrival time of incoming cells as input linguistic variables to reflect the usage situation in advance. Simulation results reveal that the proposed FUPC possesses shorter response time to detect violation cells, keeps the output rate of the user close to the declared usage parameters, and thus achieves more precise control than DLB.
