摘要
随机早期确定(random early detectim,RED)算法是网络拥塞控制策略中基于网络节点的一种主动管理队列技术。就该算法的缺点—滞后效应进行了研究和探讨,并提出了一种基于分组丢失和链路使用历史的解决办法,使得RED的滞后效应得到克服,最后并用NS进行了仿真研究。并就仿真方法进行了探讨。对RED和blue算法用NS就队列长度、平均队列长度、吞吐量等进行了对比分析。
The RED algorithm is in the network congestion control policy based on the node one kind of management by initiative formation technology. The research and the discussion effect is conducted, and proposed one kind based on the grouping loss and on this algorithm＇s shortcoming-lagging the link use history＇s solution, enables RED the lagging effect to obtain overcomes, finally and has conducted the simulation research with NS. And has carried on the discussion on the simulation method. To RED and the blue algorithm with NS on the queue size, the average queue size ,the volume of goods handled and so on has carried on the contrastive analysis.
