Internet plays a vital role in day-today’s regular activities and hence has become the backbone of our society. In internet the data is transferred from one place to another with the help of most commonly used protocol known as Transmission Control Protocol (TCP). TCP possesses various variants and each one has different criteria such as TCP, Tahoe, Reno, New-Reno and so on. Each variant performs in a different routine for different networks based upon the various key parameters. In this paper we have simulated various TCP variants with respect to different network parameters such as variable packet size, bandwidth and buffer size. This paper analyses the throughput, packet drop, delay and jitter of TCP variants evaluated over the above mentioned network parameters. June - August 2015 Copyright © 2015 i-manager publications.
