Network simulator is a significant tool for researchers to simulate the actual network. The main advantage of the simulator is that it gives results much closer to the reality than the mathematical modeling. Furthermore, its cost is much lesser as compared to the real experimentation. The scale and size of the large networks (e.g. Internet) complicate both the mathematical modeling and the real experimentation. Therefore, researchers depend mainly on simulators to study, evaluate and design the performance of network. Optical Burst Switching (OBS) network is one of the most popular research areas in the optical Internet.
