In this paper, two TCP variants are compared in different scenario. Transmission Control Protocol (TCP) is a reliable, end-to-end transport protocol which is most widely used for data services and is very efficient for wired networks. It also performs well in wireless networks. It is the backbone protocol of most of the internet based applications. The authors' analysis is on performance of TCP variants. In this paper, they carry out performance study of TCP Sack and TCP Vegas to be able to classify which variant of TCP performs better in various possible scenarios. This paper describes an NS-2 based simulation analysis. By varying different parameters and congestion control mechanism they will check its effect on throughput.
