More and more of the computer connected to the different network, computer network no matter from the structure or scale have undergone great changes, the computer network construction, and puts forward the new challenges to implement network project has also put forward new requirements. As office informatization, automation needs, each enterprise to improve office efficiency, promote the exchange of information, to adapt to the requirements of the modern office, enterprise network construction is the enterprise to the inevitable choice for the development of informatization, enterprise network system is a very large and complicated system, it not only for modern enterprise integrated management and office automation and so on a series of applied to provide basic operation platform, but also can provide various application service, so that the information timely and accurately transmitted to each system. It directly related to the enterprise can obtain the key competitive advantage. The plan's main goal is to according to the company's LAN Yang construction demand as a background, based on the computer network technology as the foundation, a detailed design the enterprise network construction plan. This graduation design mainly from requirements analysis, enterprise network topology structure, equipment selection, network security design, route design, etc., are analyzed and described, and the specific design scheme is presented.
