On the problems of some AQM (Active Queue Management) algorithms having more long response time and being not able to stabilize the queue length near the expected value for the networks with large time-delay, a new intelligent PID (Proportional Integral Differential) is proposed as active queue management algorithm. The detailed statement of this algorithm is given. Simulation results show that the new algorithm is stable and robust when the time-delay is small, and the response speed of this algorithm is faster than that of some existing algorithms such as REM (Random Exponential Marking),PI(Proportional Integral), and PID controller. At the same time, for the networks with large time-delay, this algorithm is stable and convergent.
