Performance Analysis of TCP Tahoe, Reno, New Reno, Sack and Vegas using NS-2

Abstract

The Transmission Control Protocol (TCP) is the dominating end-to-end protocol on the internet today but still it faces congestion problems in some cases. To overcome congestion problems, several congestion control and avoiding mechanisms namely: Tahoe, Reno, Vegas, and Sack etc. all with different features and advantages but with maximal throughput as main objective, which are termed as the clones of TCP, have been incorporated into TCP/IP protocol for handling congestion efficiently in different network scenarios. However, one clone cannot be suitable for each case. So this paper has investigated the characteristics of the mentioned clones and calculated throughputs of them in simulated environment varying various performances metrics such as delay, buffer size, error rate, number of traffic and bandwidth for finding which one is the best for what scenario.
