The overall goal of the education metropolitan area network construction is to use a variety of advanced and mature network technologies and communication technologies and adopt a unified network protocol (TCP / IP) to build a high-speed computer network system that can realize various integrated network applications The colleges and universities directly under the Provincial Department of Education are connected through the network and connected with CERNET and Internet.
In order to better support new application functions, the network can not only stay on providing greater data bandwidth, but need to provide more specialized network services. Because for education and research networks, expanding bandwidth is not a panacea, network equipment also needs to provide end-to-end QoS, security and prioritization and network manageability.
The switch equipment on the Education Metropolitan Area Network adopts high-performance, modular, and routing switches that support Layer 3 switching. Based on the switching capabilities of Layer 2, 3, and 4, the mesh topology can not only achieve redundancy on the connection And, the use of OSPF protocol can achieve multi-link load balancing.
According to the analysis of the education metropolitan area network, Tongfang Network recommends the use of TFS9516 high-capacity enterprise routing switches at the core of the education metropolitan area network. The routing switch is a rack-based switch that can provide users with different functional modules. Each rack can be installed with 16 modules, providing multiple types of I / O boards to meet different networking requirements of customers. It can be organically connected with TFS9000, TFS8000, and TFS7000 series switches of Tongfang Network Company to provide a more complete end-to-end network solution.
For the backbone of the education metropolitan area network, the Tongfang network uses 4 TFS9516s to perform dual-ring backup through the GE port. The district and county education bureau serves as the network convergence layer, and nearby schools are directly connected to the district and county education bureau network. The district and county education bureau uses one TFS9516, two GEs are connected to the backbone network and two TFS9516s are used for dual-channel backup. The school uses the same side network TFS9508 as the uplink access device. Schools close to the backbone network or some key schools are directly connected to the backbone of the metropolitan area network. The school can use TFS9508 dual GE to connect to two TFS9516 on the backbone network.
For the wide area network interconnection of the municipal education commission, county education commission, and county-level school, the Tongfang network uses TFR routers to connect with 2M dedicated lines. For township schools in remote areas that do not have dedicated line services, they are connected to the county education commission by microwave. The education metropolitan area network export uplink uses TFR3660 router to connect to CERNET and Internet respectively. The municipal education committee network center uses the Tongfang network TFS9516 high-capacity enterprise routing switch as the central switch, and the county education committee and county-level schools use the Tongfang network TFS9000 series routing switch as the access switch.
