TCP拥塞控制算法仿真实验设计

摘要
为了更好地利用网络资源和保证网络服务质量,TCP拥塞控制研究显得尤为重要。针对影响TCP性能因素RTT和RTO的参数设置问题进行了探讨,设计一组相关的实验项目,在同构网络拓扑结构下,采用NS2分别对TCP Tahoe、Reno、New Reno、Sack和Vegas的拥塞窗口和吞吐量进行仿真对比,并对4种典型版本TCP拥塞控制算法的运行效果进行了模拟,得到不同TCP拥塞控制算法的优缺点以及所适应的网络环境,为计算机网络的实验教学提供一定参考。
In order to make better use of network resources and ensure network quality of service, TCP(transmission control protocol) congestion control research is particularly important. This paper discusses the parameter setting of RTT and RTO which affect TCP performance, and designs a set of related experimental projects. The congestion windows and throughput of TCP Tahoe, Reno, New Reno, Sack and Vegas are simulated and compared by NS2 under the same network topology. The running effects of four typical versions of TCP congestion control algorithms are simulated, and the advantages and disadvantages of different TCP congestion control algorithms and the suitable network environment are obtained, which can provide some reference for the experimental teaching of computer network.
