| Abstract: | For the congestion of high-speed communication networks, a fuzzy immune-PID controller was designed to adjust the rates of ABR on-line in ATM networks. And an algorithm was proposed to guarantee the minimum cell rate. The control algorithm designed can overcome the adverse effect caused by uncertainties such as the number of users, the ABR bandwidth and propagation delays etc and the fairness and full utilization of bandwidth are also ensured. Simulation results show that the control system is rapid, adaptive, robust, and the quality of service is guaranteed meanwhile. |
