(Construction of campus network: unified design, distributed implementation; construction of network system; management of campus network: easy operability of network management; use management platform to monitor, analyze and monitor the running status of campus network, quickly judge, Find and eliminate network faults; pay attention to security management. In the construction of campus network engineering, an important branch of network technology, local area network technology, is mainly used for construction and management. Therefore, this graduation project will mainly focus on various technologies and implementation plans that may be used in the construction of campus local area network. , to provide theoretical basis and practical guidance for the construction of campus network.)
