The Design And Implementation Of Frowarding Function In The Centralized WLAN System At The Wireless Access Point

With the development of network technology, the network has been a necessary part of people’s life. With the demand for network mobility increasing, the wireless network plays a more and more important role in people’s life. Improvement of wireless network technology has been our necessary task. In this paper, a new function in the WLAN wireless network has been created, in order to improve the overall function and treatment efficiency of wireless networks.In the centralized WLAN architecture, there are two kinds of network packet forwarding mode--local forwarding and centralized forwarding. Based on the original two forwarding modes of foundation, a new forwarding mode, forward policy mode has been created. According to user’s policy, a part of the network packets are local forwarding, another part are centralized forwarding. Forward policy mode through strategy, can effectively reduce the workload of wireless control point, part of the network packet forwarding to be shared by the wireless access point. At the same time, users can also effective control of the network packet forwarding mode based on your own needs, different strategies.This paper, using the software engineering "V" model of development pattern, made a detailed analysis and introduction to the wireless access point part in the strategy forward project,. There are analysis, outline design, detailed design, coding, unit testing, systemic testing, debugging and problem solutions. In the design phase, there are three different strategies, through analysis and debugging, the optimal solution has been selected.In the testing phase, the problems have been corrected based on testing and unit testing for the project. Finally, the normal operation of function has been ensured, and in the new version of the product, forward policy mode has been joined.
