TCP性能增强代理包处理策略的研究

Study of packet processing strategy in model of enhancing TCP performance

为了提高传输控制协议在长时延、高误码率的异构网络中的传输性能,利用在异构网络的边界处设置具有传输控制功能的性能增强代理的理论模型,通过实现一种阈值的动态调整算法,动态地控制该模型中提前应答的发送速度。仿真实验结果表明,该模型对提高异构网络吞吐量、避免拥塞的发生具有良好的作用。

In order to improve transmission performance of TCP protocol in heterogeneous network of the long delay, high error rate, A theoretical model of installing a performance enhancing proxies （PEP） is utilized, which has functions of transmission and control at the border of heterogeneous network. The simulation shows that can do well on enhancing network throughout and avoiding the occurrence of congestion by realizing the watermark of dynamic adjustment algorithms and by dynamically controlling the speed of sending Pre ACK.
