Analysis of Shenzhen University City Network Construction

The construction of the network and information system of the Shenzhen University City is an important part of the construction of the Shenzhen University City. It is an important information infrastructure to realize the cooperation between Shenzhen and domestic famous universities. It has important demonstration significance for the implementation of modern distance education projects in China. Starting from the actual situation of the university city, it is necessary to set up a central node in the network center of the university city, and a master node in each of the three campuses of Tsinghua University, Peking University and Harbin Institute of Technology. There is one central node, the number of main nodes is three, and there are about 17,000 information points in each campus network. The university city will provide public information services and management systems for the universities, and realize graduate-oriented education, including education-oriented comprehensive information systems, video application systems, IP phones, and network-based teaching environment construction, and has the next generation Internet IPv6 Function, openness, standardization and versatility.

The network construction of the Shenzhen University City is divided into the university city interconnection layer and various campus networks. Among them, the university city interconnection layer is the university city network center and three schools for wide-area star interconnection, using 10 Gigabit backbone, Gigabit backup fiber direct drive links, and using Huawei ’s 3Com core router NE80 as the university city exit, thereby making The reliability of the network is the highest. At the same time, the fifth-generation router technology of NE80 is used to realize multi-service wire-speed forwarding and support IPv6.

Each campus network also uses Huawei 3Com's chassis-type switch S6506 as the regional aggregation, and uses the S6506's wire-speed forwarding capability and high stability to ensure the smoothness of the campus network's internal network. S3026E as a building layer switch to achieve end user access, using the 3026E stacking function to save links and ports, S3026E has powerful wire-speed forwarding and efficient flow classification, QoS support capabilities, while supporting user management and binding, to achieve the entire campus High security of the network.

The complete solution has the following characteristics: efficient forwarding performance, the product has wire-speed forwarding performance under heavy service load; powerful flow classification capabilities and QoS support capabilities, enabling simultaneous transmission of multiple business streams such as video, voice, and data ; Powerful fifth-generation router technology, using network processors to achieve wire-speed forwarding and subsequent support of services, supporting IPv6, MPLS VPN; high stability, using mature products and key device redundancy, and supporting multiple redundancy technologies Reliability of the entire network.

The construction of the information network of Shenzhen University Town can realize the loading of information systems and management systems, realize the information exchange and resource sharing between schools and our school, realize the digitization of distance teaching, video and voice, and not only ensure the long-term and stable operation of the network. The loading of various services, and the use of a unified and standardized platform are conducive to later expansion and upgrade.
