摘　　要：主动队列管理(active queue management,AQM)算法和TCP拥塞控制相结合,是解决目前Internet拥塞控制问题的一个主要途径。主动队列管理算法中,随机早期检测(Random Early Detection,RED)算法是最常用的一种方法。本文利用NS2仿真软件模拟网络环境对RED算法进行仿真,通过吞吐量、时延、抖动等指标来分析其性能,并且针对RED算法的不足提出了改进措施。It is a main approach to solve the congestion in internet by combining AQM algorithm with TCP congestion control, and RED algorithm is the mostly used method in AQM. It simulates RED by designing network environment with NS2 simulation software, and it analysis the performance of RED by several indexes, such as throughput, time delay, jitter. Considering the disadvantages of RED, it puts forward some improvement to RED.

关 键 词：主动队列管理 随机早期检测 吞吐量 时延 抖动
