Design Of Wireless Access Controller's System Software

Now, people want to break away from line's restriction, wireless communication network has become a hot topic, especially include Wireless Local Area Network (WLAN). WLAN can help notebook computer and PDA mobile terminal take off line's connection, and connect with Internet freely. So the investment of basic device can decrease, and solve the access difficulty in poor place. Compared with wired network, WLAN is convenient, flexible and expanded easily. It can provide service for hospitals, stores, enterprises, schools, center of conference, railway stations, hotels and so on. Therefore the application of WLAN is wide.With the popularization of WLAN, large numbers of correlative network products is needed. This paper designs a wireless access controller's system software based on IEEE Std.802.llb. In WLAN architecture, wireless network is connected with wired network via some access points, but these access points need a AC to manage and control centrally, in the same time it is important that AC can protect the wireless network's security. This paper mainly discusses the design and the realization of AC's software system, it accomplishes AC's core function, partly solves WLAN safe problem, promotes WLAN commerce application, also has study consulting and practical value for actual products.Take advantage of the Object-Oriented tool, this paper uses UML to design and uses C++ programming language on VC developing environment to implement the system software.
