The Study Of Centralized Networking Scheme Of The Carrier-class WLAN

Wireless Local Area Network has the merit of high speed, wide cover and simple wiring, it becomes an advantageous fashion for the telegraphic Corporation to build their wireless broadband network. The earlier Wireless Local Area Network was a distributed network, it was flexible, simple and compliant, and it was be the same with early periods, but it can't support new applications. Centralized network can manage the network equipment expediently and safely, it is the developmental direction of WLAN. But the old network has been sweeping. The telegraphic Corporations have to think over the centralized networking scheme of the carrier-class WLAN.Firstly, this article analyse the most difficulties of the centralized networking scheme,which are the dificulties of integrating centralized network into the access network, using the old unitive network management system and attestation system. Secondly the aricle takes status of the current network into account, enumerates three networking scheme, and discusses each project's characteristics and applications. Then the article focuses on the implementation of unitive network management system and attestation system. Finally, the article built an experimental platform to test the network management and attestation of three familiar networking. The result shows that the centralized networking scheme works effectively.
