Bengbu Education Metropolitan Area Network Case
The purpose of building campus network is to use modern network technology and information management technology to realize the modern management of campus, multi-level and multi-faceted scientific research and education tasks. Therefore, in the network construction, the education resource center should be considered as the central node, and several backbone nodes should be set up to form a backbone network. The powerful and unified metropolitan area network management platform, a reasonable combination of various hardware devices and actual demand applications. There is a rich educational resource center (including electronic library, multimedia information service center, a large number of teaching and research materials, courseware, materials, teaching plans, policies and regulations, etc.) school students and teachers can use digital, networked teaching environment to break through time And space constraints, timely access to the Internet to obtain knowledge and courses. Basic network planning: Make full use of the high-speed broadband IP backbone network covering the entire city (district) of Bengbu, so that all primary and secondary schools and education departments in the city can achieve broadband interconnection in the education industry. Adopting switched Ethernet technology and using different network solutions according to different scales of the school, the entire education metropolitan area network includes the following: 1. Bengbu Education Committee Network Information Center Network 2. School network subnets at all levels and types (larger schools, medium-sized schools, small-scale schools) 3. Broadband interconnection solution for education metropolitan area network Program content: (1) Use Shenzhou Digital Network Co., Ltd. to enrich the full range of network products, build an education metropolitan area network education committee information center, and various school campus network overall solutions, (2) Adopt a unified all-Chinese network management system LinkMananger network management platform. Establish complete information control and network monitoring management. (3) The school-school interconnection uniformly adopts DCR-1700 router to achieve broadband access and supports future value-added services (VOIP phone, VPN, video conference). (4) Filter the bad information through the DCFW-2000 fire wall to provide security protection functions. Larger schools: (Bengbu No. 1 Middle School, No. 3 Experimental Primary School) – Adopting high-performance three-layer switching technology to ensure that the large campus network has high performance and high security; – The core switch DCRS-7500 has carrier-class fault tolerance, ensuring high reliability of the network; – Support rich network interface types, including metropolitan area network remote connection; – Enhanced multimedia and QoS function support, which can meet the multimedia transmission needs of large traffic; –All Chinese network management system, easy to manage and maintain; – Fire wall for safety protection and filtering of bad information; – Support VOIP voice phone, VPN encryption value-added applications. Medium-sized schools: (Bengbu No. 6 Middle School, Bengbu No. 5 Middle School) – The use of three-layer switching technology can improve the controllability and security of the network, and improve the bandwidth utilization; – high performance, high reliability, easy management and maintenance. With star connection, the failure of peripheral equipment will not affect the entire network, as long as the reliability of the central switch is improved, the reliability of the entire network can be improved; – Strong scalability, using DCRS-6512 and DCS-3628S stacking groups, the number of new modules and stacking switches can be increased according to the development of campus network, and up to 500 10 / 100Base-TX ports can be expanded; – High flexibility, can support a variety of speeds and media types, and can make full use of the original equipment while upgrading and expanding the network backbone; – Support LinkManager full Chinese network management system, easy to manage and maintain; – Adopting NAS network storage server can effectively reduce the cost of the storage system and improve the security and expansion flexibility of data storage. – Firewall for security protection and filtering of bad information; Small-scale schools: (Bengbu Vocational School) – Cost-effective, easy to manage and maintain. Using star connection, as long as the reliability of the central switch is improved, the reliability of the entire network can be improved; – Strong scalability, using DCR-3652, DCR-2426 and DCS-3628S stacking group, the number of switches can be increased according to the development of campus network; – High flexibility, can support a variety of speeds and media types, and can make full use of the original equipment while upgrading and expanding the network backbone; – Fire wall for safety protection and filtering of bad information; – Support LinkManager full Chinese network management system, easy to manage and maintain.
