Abstract

The present invention provides an access control method, system, and access point. When the AC fails, the AP configures the network layer interface of the AP according to the AC's IP and MAC addresses learned in advance, and then the AP uses the configured The network layer interface routes the received first STA message requesting to access the external server to the Web server in the WLAN, realizing the interconnection and intercommunication of the wireless LAN, and avoiding the occurrence of AC in the centralized network architecture. The breakdown of the wireless LAN caused by the fault.

Description

technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular to an access control method, system and access point. Background technique [0002] Generally, a large-scale wireless local area network (Wireless Local Area Networks, WLAN for short) adopts a centralized network architecture, including an access controller (Access Controller, AC for short) and an access point (Access Point, AP for short). Apart from providing radio frequency signals, the AP basically has no management and control functions. In order to realize the function of wireless local area network, besides AP, also need to have the equipment AC of management control function. The main function of the AC is to manage and control all the APs in the WLAN, and it cooperates with the APs to complete the WLAN functions. One AC can control and manage multiple APs. After the AP receives the message sent by the workstation (station, STA for short), it tran...
