主动队列管理(AQM)中的算法改进研究

Reaserch in AQM Algorithm Improvement

当今时代,远程通信技术飞速发展,网络用户人数呈几何级数激增,这就使解决网络拥塞成为了一个亟待解决的问题.网络拥塞不仅会使网络通信质量下降,还会影响用户的服务质量水平QoS(Quality of Service),甚至还会影响到网络安全.本文通过分析当今因特网中流量控制,拥塞管理以及服务水平提供的机制,如TCP/IP协议中的开环,闭环控制和主动队列管理机制(AQM),介绍了一种改进之后的算法,将其与早期的简单弃尾算法和RED算法相比较,并将实验结果进行了总结.

Nowadays, telecommunication technologies are developing rapidly, and the number of users of the intemet is growing even faster. All these above make congestion control a prominent issue of the network. Besides, the issue may degrade QoS, lower throughput or even have something to do with internet security. In this thesis,we mainly analyzed the Internet congestion control system, proposed a optimized algorithm,compared it with droptail and RED then summarized what we got from the experiments.
