The Planning And Construction Of Campus Network

The campus network is a large and complex system, it can not only provide a platform for the modern teaching, comprehensive educational administration management and office automation, but also offer a variety of application services for the daily office and teaching. The design and implementation process of the campus network in Radio and Television University is introduced in detail in this thesis, according to the related network techniques and functions, based on the background of the new campus network planning and the old campus network upgrading in Radio and Television University.In this thesis, the conceptions of campus network are briefly introduced, the organization demands for the new campus network are analyzed from the aspects of user demand, business demand and network topology structure demand. Based on above analysis, the design objective is clear and the design planning is formulated. This thesis designs the popular three-layer network architecture model which including core layer, aggregation layer and access layer. This model uses Gigabit switched Ethernet as the mainstay, realizing fast to the desktop. For the network export, the dual exports of Unicom Gigabit and Carnet Fast are used. According to actual conditions, the S8610S5750and S2900switches made by Ruijie are used as the core layer, aggregation layer and access layer respectively. The NPE50-20made by Ruijie is chosen as the export router, and the IBM series servers are selected as the host computer. Meanwhile, the network security analysis and IP address planning are introduced in this thesis. In combination with business changing of the old campus, upgrading solutions of hardware equipment are also proposed.The scheme mentioned above not only meets the current demand, but also conducive to upgrade and expansion.
