Network simulation has become an integral part of most research works in the field of Computer Networks. Whether it is for understanding the behaviour of existing protocols, or to determine the performance of a new protocol, one doesn't often get access to real network devices. This gap has been filled up by network simulation to a large extent.
In this experiment we will get familiar with one of the most popular open source network simulators, Network Simulator version 2 (ns2). The experiment makes one familiar with fundamental concepts of ns2, and provides step-by-step instructions on how to install it.
