Analysis And Design Of Pre-Configuration Management Module In Ac Of Wlan

With the high development of mobile communication business, the speed and QoS (Quality of Service) of wireless network transmission face the challenge. The WLAN based on802.11n wireless network protocol which provides higher throughput has become the mainstream, and the scale of wireless local area network is getting huge and complex. In the current WLAN system, there are hundreds of FitAPs (Fit wireless Access Point) which are controlled and configured by one single AC (Access Controller). But the standard protocol CAPWAP (Control And Provisioning of Wireless Access Points Protocol Specification) between AC and FitAPs does not support encrypted transmission, and this would produce a number of potential safety hazards.This subject is aimed to establish the IPsec security connection while the CAPWAP connection is established between AC device and FitAP devices. And the safety and stability of WLAN system would be enhanced greatly.In order to establish IPsec safety connection between AC and FitAPs, we would configure FitAP devices firstly. The pre-configuration management module in ac is designed and implemented in this thesis. This module is used to create and send pre-configuration to FitAP equipment, and the FitAP would configure itself automatically when it restarted next time. Then the FitAP which has been configured could establish IPsec security connection with the AC equipment through CAPWAP protocol. The generality of pre-configuration management module have also been considered, and this module can be used to give any pre-configuration else.In this thesis, some commands related to pre-configuration management have been added to AC system. WLAN administrator would use these commands to maintain and manage pre-configuration for FitAP, and the IPsec safety connection would be established between AC and FitAP conveniently and effectively.
