Tuning PI/PID Congestion Controller for Active Queue Management

Active Queue Management strategies are important means for internet congestion control. However, it is hard to configure the controlling parameters to achieve good tradeoff among a set of performance objectives. Much work is devoted to find effective ways to parameter tuning. A simplified PI/PID controller for Active Queue Management was proposed and an empirical formula was utilized to tune the parameter of the controller. Simulation results demonstrate that the new controller shows some advantages over the traditional ones.
