(School Campus Environment Analysis XX school consists of 5 teaching buildings, 4 student dormitories, an administrative building, a library, a gymnasium, and a science and technology building (also known as an experimental building). The campus covers an area of ??3 million square meters. The network core is located on the 2nd floor of the Administration Building. As a new building, the Xinzheng Building needs to carry out integrated wiring. The teaching building, library, gymnasium, and science and technology building have all been wired in the early stage. Student dormitories are not included in the construction design of the campus network for the time being. Second, ?? XX school digital campus design and construction goals 1. ??Basic requirements to build a campus backbone network with campus office automation, computer-aided teaching and modern computer campus culture as the core, relying on modern network technology, advanced technology, strong expansibility, and covering all buildings on the campus. All kinds of computer system equipment are connected and connected with the Internet to form a new campus computer network teaching system with reasonable structure and internal and external exchange. On this basis, build a software and hardware environment that can meet the needs of teaching, scientific research and management and office, develop and construct various teaching resource libraries and use systems, and provide teachers, students and parents with sufficient network information services. After the computer network system is completed, it will not only provide a high-efficiency office environment for the school, but also be used for the connection of various subsystems and various computer software and hardware resources on the campus, as well as the safe and efficient interaction with external network systems such as educational information systems and the Internet. Connect, become the central nervous system of the entire campus. 2. ??Network structure requirements (1)? Conduct integrated wiring for the administrative building, and set up a network core on the second floor; (2)?? Connect the administrative building with the original science and technology building, teaching building, library, and gymnasium to form a campus Network backbone network; (3)? Add a gigabit module to the switch of the computer core on the 5th floor of the original science and technology building, and use gigabit optical fiber to connect to the network core; (4)? The campus network adopts a gigabit Ethernet backbone switch, 10M/100Mbit /s exchanged to the desktop; (5) Special classrooms, computer rooms, electronic reading rooms, etc. need to build physical subnets; (6) The electronic reading room has a large information flow, and needs to use gigabit fiber to connect the core switch; ( 7) ?? Divide virtual networks for different functional departments; (8) ?? Core switches are planned to use well-known brands such as Cisco; (9) ?? Apply for two Internet channels, one is based on the original science and education network)
