Problems solved by technology

[0013]During the above access process, if the AP fails to access the AC, or the communication with the AC is interrupted after access (for example, the AC fails), you need to re-execute the access from the AC. The access process started in step 101; in addition, there is no information sharing between ACs, and each time the AP accesses, it needs to download the version and configuration information again, which leads to the slow speed of AP accessing the AC, and the failure of the AC The switching speed is slow

Embodiment Construction

[0041] In a specific embodiment of the present invention, the AP saves the AC list obtained from the DHCP server, and when the access fails or the AC fails, the AP selects another AC from the saved AC list to reconnect. In another specific embodiment of the present invention, communication is also carried out between each AC, and the version and configuration information of the locally saved AP are notified, so that the AP information among the ACs is kept in sync; It also carries the version and configuration information, which is judged by the AC and indicates whether the AP needs to download the version and configuration information.

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] Please refer to Fig. 2, the method for the AP accessing AC of the specific embodiment of the present inve...

Abstract

The invention provides a method for accessing AP to AC in wireless local area network and access equipment. The method comprises that the AP obtains an AC list from a DHCP server and stores the list; the AP selects an AC from the AC list and is accessed to the AC; when the access fails, the AP selects other ACs from the AC list and carries out the access. According to the invention, the speed of accessing the AP to the AC can be improved effectively.

Description

technical field [0001] The present invention relates to a wireless local area network (Wireless Local Area Network, WLAN) technology, in particular to a method and an access device for an access point (Access Point, AP) in a wireless local area network to access an access controller (Access Controller, AC). Background technique [0002] WLAN provides a wireless connection service of a local area network. Because it can provide high-speed wireless data access, WLAN is one of the more popular technologies in the IT industry at present, and it is also a popular wireless access method. WLAN usually adopts a centralized AC-AP architecture, in which the AC provides centralized management of the WLAN network, and the AP establishes a connection with the AC and joins the WLAN network to provide wireless access services. [0003] The existing control and provisioning of wireless access points (Control and Provisioning of Wireless AccessPoints, CAPWAP) protocol defines a centralized W...
