Abstract: A fluid-flow model is presented for feedback control system of HSTCP and the AQM(Active Queue Management).Based on this model,the stability of the closed loop system is analysed.Adopting frequency-domain stability margin,the stable parameters domain of the RED algorithm in high-speed TCP/AQM is obtained.Simulation results based on MATLAB/SIMULINK show the method is effective.

Key words: high-speed Transmission Control Protocol(TCP), active queue management, Random Early Detection(RED) algorithm, congestion control
