Abstract

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
