INTRODUCTION

Network Simulator is software used to simulate a wide range of real world networks and study the behavior of the network without using physical network components. The program performs this by tracing the interactions between the different network entities (hosts/routers, data links, packets, etc) using mathematical formulas. The behavior of the network can be observed for the various user inputs. Various attributes of the environment can also be modified in a controlled manner to access these behaviors under different conditions.
Simulation processes are based on the actual behaviors of network devices and protocols. We have presented a practical use for the implementation of network design and analysis tools.

1.2 Problem statement
The SNiP Network Simulator helps in design, study and observe the behavior of various networks without using the actual networking components. It also plots required graphs to study the data transfers carried out, packets dropped and collisions occurred.
