Transmission rate manager for fuzzy traffic control of ATM network

The paper presents methods for the improvement of performance of a fuzzy traffic controller that simultaneously manages congestion control and connection admission control for an 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. We introduce a new rule set for the congestion control part of the fuzzy traffic controller and add a transmission rate manager to adjust source rates of data traffic. Simulation results show that the total system utilization improves from 69% to 98.5% and cell loss probability reduces from 2.9 e-3 to 1.85 e-5
