| Nowadays, Every corner of our life is around the mobile internet. So that, people more and more can not do without mobile internet in their work, study and life. The construction of campus network in colleges and universities transform from the wired network to the wireless network. Due to the large-scale users, various business types, indoor and outdoor coverage, high security of the wireless campus network, the wireless campus network architecture has its own characteristics. Therefore, studying on the wireless network architecture has become an important aspect of the construction of the campus network.In the first part of this thesis, the current domestic and foreign institutions of the wireless campus network construction is analyzed. In the second one of it, the development and related technology of wireless LAN is analyzed. In the last one of it, the author put forward a design scheme of wireless network architecture.The network structure of the three layer AP+AC design using dual core equipment, dual convergence link and high density access. The core layer and the convergence layer use high performance switch of ten thousand million. The core layer is responsible for routing packets and high-speed forwarding. The convergence layer is responsible for routing convergence and control strategy. The access layer is made of high density port, safety control strategy with POE port switch and wireless AP, power supply and safety control of wireless network users a huge number of high-speed access and switch to AP. The design adopts double AC redundant architecture and AC is in the core layer, which is responsible for the whole network and wireless AP management, security authentication, roaming and other functions so that it solve large-scale wireless network management and the security and stability of AP.The design also completed the IP address of the network planning, network routing, flow control, export access control, intrusion detection and protection and some security protection of export control of network. At the same time, the authentication of the network access security control and the network security system construction are accomplished.Finally, the thesis puts forward some testing schemes of wireless network for the design of the network. These schemes include AP signal coverage and strength test, distribution channel test, automatic switch test of standby AC, AP roaming test and the illegal AP access counter test. |
