nowadays it’s hardly to predict the network behaviors by mathematics formula because of computer networks complicacy for this reason engineers use simulators to predics the network behaviors. Network simulator is usually the first place to verify a new idea . this paper describes in detail the simulation model actual measurements that are taken and input to the model validation and what -if scenarios that are run in order to understand the behavior of the application in different situations.
