Optimum Design for Campus Network with Efficient Rate of Delay and Throughput

Information Communications Technology ICT Nowadays has become a very important part of our life, due to its useful facilities and activities in various area. However, campus network has been considered as a branch of ICT applications that serve universities and institutes in communications and academic learning. Designing a useful network for campus leads to improvement of performance and scientific research of any university, through campus network new laboratories will be available, online library for books and software, as well as, building VoIP communications between the departments of universities. In this paper, a new campus network model has been proposed for Zakho university, Copper and fiber mediums were suggested as communication mediums, also. The designed network provides a number of services such as electronic mail (Email), web browsing, E-learning, and file transfer service. Each one is provided by a dedicated server at the data center of the university. The model is simulated by utilizing an OPNET simulator program (OPNT IT Guru 14.5) Network performance was evaluated in term of throughput, delay, and utilization with different load scenarios namely, (light load, medium load, and heavy load). The result showed that the proposed network is highly efficient even with heavy load scenario, resulted average throughput rate was more than 60Mbps without packet filtering technique while it was 50Mbps with packet filtering, whereas in current wireless Network, it is 2 Mbps Results showed that delay in the wireless mode is 72ms, while the wired test resulted of 13ms delay Furthermore, this model supports many network applications in future like voice over IP (VOIP) and (E-Learning).
