HSTCP是一种适用于高带宽网络的拥塞控制机制.建立一种适用于HSTCP和AQM反馈控制系统的流体流模型,基于该模型分析闭环系统稳定性,并得到PI控制器参数的确定方法.仿真结果验证了该方法的有效性.
HSTCP (High Speed TCP) is a well suited congestion control mechanism for high bandwidth network. A fluid flow model is presented for the feedback control system of HSTCP and AQM (active queue management). Based on this model, we analyses the stability of the closed loop system, and obtain one method of configuring the parameters of PI controller. Simulation results show the method is effective.
