WTCP: Improved Performance of TCP for High Speed Wired/Wireless Internet

From the viewpoint of control theory, TCP congestion control system can be regarded as a feedback regulating system. In this paper, a novel active queue management (AQM) scheme, called WTCP, is proposed for TCP congestion control in high speed wired/wireless Internet. The design principles of WTCP are presented in details. Simulation results demonstrate that the WTCP AQM outperforms FAST TCP in items of window size, queue length, and self-clocking against traffic load fluctuation such as HDP and HTTP disturbance.
