computer networks design

Abstract

Networks are the backbone of an Information Technology (IT) applications, it acts as the basic carrier for exchanging information required by the IT applications. A need for a high response network appears, as essential requirement for usage of IT application in strategic planning and decision making. Designing high performance network needs a good knowledge about service and application requirement and traffic monitoring to determine the congestion points, so the design process and selection of the network components will be base on these requirements. SUST start its network with two labs, and gradually adds PCs and services to this network until it reach around three thousand of personal computers and a lot of services. The thesis study the current situation of the network from the traffic analysis point of view, and the ability of accepting new service in the future, and found that the network need to be redesigned with the new requirement. The thesis proposed a new design for SUST network solving the congestion problems and highlights the ability to add new services such as VoIP (Voice over IP), video conference…etc.
