Wuhan University Campus Network Solution

User background

Consider Wuhan University ’s complete range of disciplines and obvious characteristics, covering 11 categories including philosophy, economics, law, education, literature, history, science, engineering, agriculture, medicine and management. The school has six major humanities, social sciences, science, engineering, information science and medicine

There are 30 colleges in the Faculty and three third-class A-level affiliated hospitals. There are 20 disciplines listed as the second batch of key construction projects of the National "211 Project". The school has successively participated in scientific research and engineering construction of national key engineering projects such as the Three Gorges Project and the South-to-North Water Diversion Project, and has made important contributions to national construction and social progress.

Project Background

Considering the construction of wireless network is conducive to Wuhan University International Management School to provide better services to students. For a large number of mobile terminals, flexible access to the network is very important. The use of various information on the national information network and the Internet through wireless networks to achieve resource sharing can provide mobile terminals with efficient connection methods. Therefore, the wireless network construction of the School of International Management of Wuhan University is a typical network facing the future of networking, informationization, and the development of multimedia integrated services.

Consider that this network construction is to expand the wireless network on the original wired network of the School of International Management of Wuhan University. Wireless coverage is provided in the computerized room and some public corridors of the School of International Management, Wuhan University, so that students can connect to the network anytime, anywhere, and without restrictions. The Wuhan University School of International Management originally had a perfect network structure, and the new wireless network construction has good compatibility. There is no need to change any items within the Wuhan University School of International Management. The original network management system can be used to manage the wireless network .

User needs

Consider requesting the realization of the main project of the wireless network of the School of International Management of Wuhan University, considering the need for wireless coverage; establishing a perfect wireless network to provide students with a truly unrestricted Internet access environment. At the same time, the network should be compatible with the original network management center of the School of International Management of Wuhan University to facilitate the maintenance of the normal operation of the network. Compatible with the original charging system of Wuhan University School of International Management, simplifying the network structure. And when wiring, there must be no damage to the decoration and walls of the School of International Management of Wuhan University.

Considering the network performance, users also have the following requirements: the network must be able to safely achieve the overall design goals of the network, and at the same time be easy to use, unified user interface, standard, strong expressive; easy to install and maintain, high network operation quality; good open , Easy to transplant, expand and popularize; in the selection of equipment, it must have a better performance-price ratio; maintain technical leadership within a few years; network security meets relevant national standards.

solution

Considering the needs analysis of the School of International Management of Wuhan University, NETGEAR provides a complete set of high-performance network solutions. The network structure diagram is as follows:

Overall network layout:

The entire network is in a star topology. We choose the best place to place the wireless hotspot AP in the area where wireless coverage is required on each floor, and ensure the coverage of the wireless signal when placing. We strive to arrange the fewest points in the floor and maximize the coverage. The APs arranged on each floor are connected to the switch in the central computer room through super-five shielded twisted pair cables to achieve centralized management.

Wireless coverage:

Considering the above picture, we arrange wireless APs in a reasonable location. The wireless coverage of the arranged wireless APs should be as blind as possible and ensure the transmission quality.

When considering the overall design of a wireless network, we focused on the following issues:

Consider the selection of wireless hotspot APs, the main equipment of the wireless network, to ensure that the AP must be able to work for a long time; have good compatibility, be compatible with various wireless adapters, and preferably support the current mainstream bandwidth of wireless transmission, More importantly, it can ensure the stability and security of the data.

So we chose NETGEAR 11M multi-function enterprise wireless LAN access point (AP)-ME103. It can provide secure enterprise-level functions at an economical price. This powerful access point product allows staff to continuously access school resources, e-mail, and the Internet at the industry standard 11Mbps rate. It is not only fully compatible with IEEE 802.11b (2.4 GHz), but also forward compatible with 802.11g, providing a future-oriented method for quickly establishing a new wireless network or expanding an existing Ethernet network. The wireless distributed system (WDS) feature of ME103 enables ME103 to support five working modes: conventional AP access, relay, point-to-point bridge, point-to-multipoint bridge, and client AP (simple bridge). The security features of ME103 include 802.1x authentication in EAP MD5, TLS and TTLS encryption modes, 128-bit encryption for dynamic key exchange in EAP TLS, TTLS and PEAP modes, WPA, 64 or 40 and 128 WEP Encrypted, unique MAC address authorized access function ensures that only legally authenticated users can access effective network resources. The management features of ME103 include that it can be configured and managed through WEB, and also supports SNMP MIB I and MIBII, which facilitates the centralized management of the user. The product provides a 10 / 100BaseT port that automatically recognizes the crossover of twisted pair cables for high-speed connection to a wired network, allowing users to easily share network resources at high speed.

Consider additionally, the network management stacks 26 100M switches-
