(The 21st century is an information age with digitization, networking and informatization as the core. The rapid development of information technology makes the computer network develop very fast, and it has become a new branch of information science/science. With the development of computer network, campus network has become an inevitable development trend for schools to move towards the information age, making our country's education management develop towards intelligence. The design of campus network is a systematic project. Different design and design schemes can make the network have a large performance difference. It not only plays on the technical characteristics and use attributes of the network itself, but also plays a role in the various users of different users. The construction of the campus network will definitely play a strong role in promoting the school's informatization construction and the improvement of teaching quality, and at the same time provide a simple, effective and convenient ideal office and teaching environment. Through the research on campus network construction, this paper analyzes and describes the requirements analysis, campus network design, equipment selection, network interconnection equipment configuration, etc., and gives a specific design scheme.)
