Modeling and Modulation

Modeling and simulation

Introduction

The concept of simulation, computer networking, is based on, "Modeling" Modeling computer networks in real. Real World Networks on a computer screen using a computer program Software is dedicated to this purpose. It is intended, the real computer networks, networks are already implemented on the ground, or networks that wish to implement in the future. The benefit of this idea, that, as long as possible to model these networks by using the computer, all the characteristics of components and everything related to it, it is possible to change or control. The process of modeling this or simulation, using computer software, is the process of low-cost as measured by Itaqalev implementation of the network on the ground without the previous study, taking into account, all the trials may be, parts and equipment that may be changed, and perhaps more than once until we reach to the target .

Consider a simple example of this: Imagine that the company wants to expand its network wired or wireless LAN, is required, add more computers, wires, and other pieces such as Access Points if we are talking about WLANs, any wireless local area networks. But, have you after all these additions and changes you will get the best performance of the company's Performance, or rather the best performance? Let's remember that this process of change is a costly process, and that the cost increases as the increased size of the network and equipment used, it can be implemented simply through the simulation program. Through this program, the network can be built on the computer screen, and then make the required changes, the collection of statistics that we wish to study, such as The Average Network Throughput and The Average Network Delay and The Server Status. Let us remember always that, through simulation programs developed, we can download the network to Traffic that we use in the network realism, which may include, for example, access to e-mail, or surf the Web, or use an FTP server or print jobs, or access to databases. In the last stage before we will run the "emulator" Simulator and finally after the completion of the simulation we will read, study and analyze the results (Johnson, Mark, & ET 2008).
