Abstract

The embodiment of the invention provides a method, device and system for processing a service message in a wireless local area network (WLAN), wherein the WLAN comprises an access point AP, a first access controller (AC) and a second AC, and the first AC is respectively connected with the AP and the second AC. The method comprises the steps of: receiving a CAPWAP (Configuration and Provisioning for Wireless Access Points) service message from the AP; according to a preset distribution strategy, obtaining identifier information of the CAPWAP service message, and acquiring the AC corresponding to the identifier information according to the correspondence of the identifier information and the AC; and sending the CAPWAP service message to the AC corresponding to the identifier information so as to ensure that the corresponding AC is used for decapsulating the CAPWAP service message. The embodiment of the invention can realize that a plurality of ACs manage the AP in the WLAN, thereby ensuring that the services of the AP in the WLAN normally operate.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a method, device and system for processing service packets in a wireless local area network (Wireless Local Area Network, WLAN for short). Background technique [0002] A wireless local area network (Wireless Local Area Network, WLAN for short) is mainly composed of an access controller (Access Controller, AC for short) and a wireless access point (Access Point, AP for short). One AC can manage multiple APs, that is, it can establish Control And Provisioning of Wireless Access Points (CAPWAP for short) tunnels with multiple APs. With the increase of APs, the tunnel resource of a single AC is insufficient, and the single AC cannot manage them, so that the services of the APs in the WLAN cannot be performed normally. Contents of the invention [0003] An embodiment of the present invention provides a method for processing service packets in a wireless local...
