【摘要】：研究卫星网络中并发TCP流的复用机制,在通过模型分析得到最优复用比的基础上,基于epoll事件驱动机制设计并实现卫星网络的并发TCP复用加速网关。研究结果表明:该加速网关可以对来自不同客户端的多条TCP流按照一定的复用比进行复用,这样,每条客户端流可以通过避免3次握手并充分利用复用流的窗口加速数据传输;所设计的加速网关均能将典型门户网页页面的加载时间和首字节到达时间最高缩短50%,可满足卫星网络的加速需求。
[Abstract]:The multiplexing mechanism of concurrent TCP flows in satellite networks is studied. On the basis of obtaining the optimal reuse ratio through model analysis, the concurrent TCP multiplexing accelerated gateway of satellite networks is designed and implemented based on epoll event-driven mechanism. The research results show that this accelerated gateway can reuse multiple TCP streams from different clients according to a certain reuse ratio, so that each client stream can accelerate data transmission by avoiding shaking hands three times and making full use of the window of multiplexed stream. The designed acceleration gateways can shorten the loading time and the first byte arrival time of typical portal pages by up to 50 times, which can meet the acceleration requirements of satellite networks.
