Problems solved by technology

[0002] With the increasing application of WLAN (Wireless LAN, wireless local area network), the traditional AC (AccessCentral, access controller)-FIT (thin) AP (Access Point, access point) network networking model is in the same network, Multiple areas need to be managed independently. For areas with low network maintenance capabilities, it will undoubtedly increase costs, and it is not conducive to centralized management and maintenance of the entire network; it will be replaced by a new generation of WLAN networks with layered thinking

Abstract

The invention provides an access authentication method and device. The method comprises the following steps: when the local AC receives an association message forwarded by an AP and from a client, ifdetermining that the ESS information of the client is same as the ESS information of the local AC, determining whether the client is the local authenticated client according to a key identifier, if the client has been authenticated, notifying a center AC to modify the access AP of the client; if the client is unauthenticated, requesting the center AC to judge whether the client has been authenticated according to the key identifier; if the center AC determines that the client has been authenticated, modifying the access AP of the client, and feeding back the VLAN information carrying the key and the client to the local AC, thereby enabling the client to perform network access through the existing VLAN information, and realizing the seamless roaming of the client.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an access authentication method and device. Background technique [0002] With the increasing application of WLAN (Wireless LAN, wireless local area network), the traditional AC (AccessCentral, access controller)-FIT (thin) AP (Access Point, access point) network networking model is in the same network, Multiple areas need to be managed independently. For areas with low network maintenance capabilities, it will undoubtedly increase costs, and it is not conducive to centralized management and maintenance of the entire network; instead, a new generation of WLAN networks with layered thinking. In this new generation network, the Central AC (center) is responsible for the management of the entire wireless network, and the Local AC (local) is responsible for AP access and forwarding data traffic, so that centralized management can be realized in the same network. In su...
