For the Asynchronous Transfer Mode (ATM) networks with time-varying multiple time-delays,a more realistic model for the available bit rate (ABR) traffic class with explicit rate feedback is introduced. A fuzzy-immune con-troller is designed,which can adjust the rates of ABR on-line,overcome the bad effect caused by the saturation nonlinearity and satisfy the weighted fairness. Also,the sufficient condition that guarantees the stability of the closed-loop system with a fuzzy-immune controller is presented in theory for the first time. The algorithm exhibits good performance,and most importantly,has a solid theoretical foundation and can be implemented in practice easily. Simulation results show that the control system is rapid,adaptive,robust,and meanwhile,the quality of service (QoS) is guaranteed.
