广域网数据传输优化技术研究

Research on WAN Data Transmission Optimization Technology

本文主要研究在利用广域网进行远距离网络通信的过程中,如何提高广域网数据的传输效率。首先,分析TCP传输协议的交互原理,并针对广域网通信的特点,从TCP数据报窗口协商和TCP应答代理两方面对TCP传输机制进行优化;其次,分析冗余数据传输、非关键数据传输对带宽利用率的影响;最后,提出从冗余流量消减和应用带宽保障两方面提高广域网有限带宽的使用效率。

This paper mainly studies how to improve the efficiency of WAN data transmission in the process of long-distance network communication using Wan.Firstly,the interaction principle of TCP transmission protocol is analyzed.According to the characteristics of Wan communication,TCP transmission mechanism is optimized from TCP datagram window negotiation and TCP response agent;Secondly,the impact of redundant data transmission and non critical data transmission on bandwidth utilization is analyzed;Finally,this paper proposes to improve the efficiency of limited bandwidth in Wan from two aspects:redundant traffic reduction and application bandwidth guarantee.
