摘要
随着因特网的迅速发展,网络拥塞日益严重,近年来提出了许多基于路由器队列管理的拥塞机制,本文分析了RED和BLUE的设计思想和算法实现。通过NS2网络仿真平台,在相同的数据流的情况下对两种算法的性能和原理进行对比,对仿真结果进行丢包率、吞吐量、平均时延等指标的分析和比较,给出结论。
With the rapid growth of the Internet, the problem of network congestion becomes worse and worse. Many network congestion control mechanisms which are used in routers are proposed in recent years. The thesis first analyses the design principle and algorithm implementation of the RED and BLUE congestion control mechanisms in routers. Then the performance and principles of the two algorithms are compared with the same data streams based on network simulator NS2. Finally, the thesis gives a detailed analysis and compares the simulation results about performance parameters such as packet loss ratio, throughput, average delay.
