Self-tuning transmission rate manager for fuzzy traffic control of ATM network

This paper presents a method for the design of a self-tuning transmission rate manger to improve the performance of a fuzzy traffic controller that simultaneously manages congestion control and connection admission control for asynchronous transfer mode (ATM) network. An ATM network requires a sophisticated, real-time traffic controller that manages connection admission control and congestion control, to guarantee the quality of service (QoS) for existing calls and to achieve high system utilization. This self-tuning transmission rate manager adjusts source rates of data traffic yielding high system utilization and low cell loss rate. Simulation results show the total system utilization improves from 69% to 99% and cell loss probability (ratio) reduces from 2.9e-3 to 3.0e-8.
