Introduction
Network being an important factor in most of the organizations, it proves to be a very costly assets to come up with. It is difficult to come up with a complete multiple networked computers, routers and data links that can be used to validate and verify a given network protocol or in other words network algorithm. The most important factor that can help in saving most of the organizations in terms of sums of money spent in coming up with the accomplished task of networked computers, routers and also the data links more efficiently. It is the use of the network simulators that can solve the main problem in this field of the networking. It is also useful in allowing the network designers to test new network protocols or even in changing the already existing network protocols in a controlled and reproducible manner.
In some form of definitions, network simulators are some pieces of software or hardware that can be used to predict the behavior of a network even without the presence of the network. The device is an imitation of the working of a computer network. The technique is believed to be an important modern technology which can be used most of the fields like the engineering, science and other important fields for different purposes. In some cases, the computer assisted simulation can be used making models and also predicting the behavior of the natural system.
Network simulators can be used in different areas most specifically in the academic research centers, industrial developers and Quality Assurance in order to design, simulate and monitor several network protocols. It is believed that the application of the technique of the simulation technology into networking area such as network traffic simulation could be relatively new in the field of technology. With the help of the network simulators, the users will be able to build very complex networks from basic building blocks like clusters of nodes and the links. With the help of the following parameters, one can come up with complex network topologies using various types of nodes such as end-nodes, hubs, routers, network bridges mobile units and more other sophisticated hardware.
It is believed that network simulation can bring into focus different characteristics depending with the environmental attributes which can be modified in assured manner to assess how the network can behave under different parameters with different configuration conditions. This aspect can still be used with different applications and services in order to observe end-to-end or from other points in a network arrangement.
At some points, there are different types of the simulators, these are, the commercial and the open source simulators. The commercial one is not for free for its user but instead, there are some fees levied for its users for them to access the software. This comes with some of its advantages, it has an up to date documentation with it despite it coming with at a fee for its services to be access. At the same time, there are the open source simulators. With this type of the simulation, the users can easily access the software without any restriction of using the money to access it. It is an open source and so it is easily available for use by the users though it has some delimiting factors too. It does not have sufficient up to date documentation concerning the same information that could be needed by the user.
In conclusion, network simulation is important in different aspects in that it has many merits in that it helps the users to come up with very complex network topologies in an organization. This helps in connecting many computers and other data links within a firm for easy access. It is recommended that most of the company’s to implement the same technique to embrace the same technology and avoid too much wiring within the office. The FPGA design is the best since it has a simple design cycle and faster time market.
