The case of Intelligent Middle School campus Network

With the deepening of the application of educational informationization, the campus network of ordinary education system has changed from simple physical network to Business network, multimedia teaching, distance education and other integrated services are running simultaneously in the campus network, which requires the characteristic of highly intelligent network.

Campus Network topology Map

Middle School hope that the campus network can form campus, campus and outside the application system of information communication, through the establishment of teaching, scientific research and management needs of the computer environment, for the school staff to provide a full range of network information services, in the network environment for teaching, research, information collection and other work. At present, the main applications of campus network include video on demand, distance education and other integrated services.

Based on the above application background, the middle school believes that the construction of campus network solutions should be technologically advanced to meet the expanding business needs, to ensure that after the completion of the network in a long period of time with strong availability.

Gigabit Backbone Hundred-Gigabit desktop

High school combined with the actual needs of the school, the various programs carried out in-depth analysis and selection, the last choice of real Tatsu Rui Jie network of Intelligent Ordinary Education Campus network solution, through the Gigabit optical fiber connection to each courtyard, department and dormitory building, to achieve "gigabit backbone, hundred trillion to the desktop."

The whole network topology is unified planning through the hierarchical structure, and the equipment with sufficient bandwidth and processing capacity is considered in the backbone network construction. The complexity of the network structure and the increase of the host require the network equipment to have the ability to deal with the broadcast storm and the large data flow. In terms of business, because of the complexity of the user structure of preparation room/teaching building/library, it is necessary for different user groups to take some means to isolate, at the same time, take full account of the necessary restrictive access between different user groups.

According to these characteristics, the central switch chooses star-s5610 modular backbone routing switch. STAR-S5610 is a new generation of multilayer Ethernet switches, it has up to 256 fast Ethernet ports, 32 Gigabit port and NAT modules to ensure the scalability of the network, with 128G (double redundancy) of large exchange capacity, even if the device itself full load of the situation can guarantee the speed of data forwarding, It effectively eliminates the bottleneck caused by the increase of network application. In addition, the Network Center equipment uses the STAR-S5610 structure compact 10 Slots modular frame, can provide the flexible disposition for the future demand growth.

According to the reasonable design principle, each converge, the access layer of the switch selects the STAR-S2024M/STAR-S2024 modular scalable Gigabit switch. STAR-S2024M is a scalable intelligent switch, it has 22G backplane bandwidth, from the machine star-s2024 has 11G backplane bandwidth, all ports can reach the wire speed forwarding, fully ensure the user's Internet speed. The tiered host provides the star-s2024m with 24 10m/100m adaptive ports and can scale up to two gigabit ports. You can stack up to 3 star-s2024 from the machine, providing 96 10/100m adaptive ports and two gigabit ports. Moreover, the STAR-S2024 series Corridor switch Body is compact, the noise is small, easy to install the school corridor.
