摘要：
Recently it has shown that the active queue management schemes implemented in the routers of communication networks supporting transmission control protocol (TCP) flows can be modeled as a feedback control system. In this paper, based on Lyapunov function we developed an optimal controller to improve active queue management. (AQM) router's stability and response time, which are often in conflict with each other in system performance. Using ns-2 simulations, it is shown that optimal controller outperform PI controller significantly.
