Wireless access method and wireless access controller

Abstract

The invention provides a wireless access method and a wireless access controller (AC), wherein the wireless access method comprises the steps of: obtaining an access request message from an access point (AP); judging whether a preset overtime stamp runs out, if so, resetting the overtime stamp and setting a total number of APs which are accessed in a current period as 1, and if not, judging whether the total number of the APs which are accessed in the current period is more than or equal to a preset threshold for the number of periodically accessed APs, if so, returning a rejection message to the AP, and if not, returning a permission message to the AP. According to the wireless access method provided by the invention, by controlling the number of APs which have been already accessed and a total number of APs which are being accessed in an access period, the APs limited by the method can be responded normally when each CAPWAP (Control And Provisioning of Wireless Access Points) channel is established, and the phenomena of disconnection and reconnection of the channel due to heavy load of a CPU (Central Processing Unit) can be avoided; therefore, the access rate of the APs is increased.

Description

technical field [0001] The present invention relates to communication technologies, and in particular, to a wireless access method and a wireless access controller (Access Controller, AC for short). Background technique [0002] In the Wireless Local Area Networks (WLAN) thin Access Point (AP) architecture, the AP needs to establish a Controlling and Provisioning of Wireless Access Point (CAPWAP) with the AC. tunnel. After the AC delivers the configuration to the AP, the AP can normally provide various services for the wireless station (Station, STA for short). [0003] In the current WLAN network, one AC is associated with thousands of APs. Due to the limited ability of the AC to handle the load, when a large number of APs access the AC, the AC cannot respond to the CAPWAP tunnel establishment request of each AP in time, and some APs fail to establish CAPWAP tunnels. The APs that fail to establish the CAPWAP tunnel continue to repeatedly initiate establishment requests t...

AI Technical Summary

Problems solved by technology

Due to the limited ability of the AC to handle the load, when a large number of APs are connected to the AC, the AC cannot respond to each AP's CAPWAP tunnel establishment request in time, and some APs will fail to establish a CAPWAP tunnel.

These APs that fail to establish CAPWAP tunnels continue to repeatedly initiate establishment requests to the AC until the access is successful, so the access efficiency is low
