Year: B.E (Information Technology)

Subject: Advanced Computer Network – Lab (ACN)

AIM:Installation of NS2 and Test network Animation on Network Simulator (NS2).
  
THEORY:
NS2 is Known to be popular open source discrete event simulator for computer networks. It is often used by some researches to help evaluate the performance of these  protocols or validate analytical models. ns2 allows you to setup a computer network, consisting of nodes/routers and links. You can then send packets over the network using a variety of different protocols at different layers. You can use ns2, for example, if we have designed new protocol to replace  TCP. We can Use ns2 to  implement  new protocol and compare its performance issues to TCP. This will allows us to test ideas before trying real-world experiments.


Network simulator 2 (ns2) is  popular open source event simulator for computer networks. It is sometimes used by researches to evaluate the performance of new protocols or validate analytical models. ns2 allows you to setup a computer network, consisting of nodes/routers and links. You can then send data (packets) over the network using a variety of different protocols at different layers. You can use ns2, for example, if you have designed a new protocol to replace or augment TCP. You can use NS2 to implement your new protocol and compare its performance issues to TCP. This allows you to test ideas before trying real-world experiments. NS2 stands for Network Simulator. Used in the simulation of routing protocols and also for networking research. It can also used for wireless and wired networks. NS2 is build from C++ and Python.
