Discovery, correlation and configuration method of wireless access controller

Abstract

The invention relates to a discovery and correlation method of a wireless access controller in a wireless communication network, which comprises the following steps: a) obtaining an IP address list of the wireless access controller according to a preset wireless access controller discovery mode, and using the obtained IP address list as an IP address list of a local wireless access controller; b) extracting a first IP address in the IP address list of the local wireless access controller; c) sending discovery request messages to the extracted IP address; d) extracting a next IP address in the IP address list of the local wireless access controller if a discovery response message is not received in the preset time, and then, returning the step c); otherwise, e) inserting the IP address list of the wireless access controller into the head of the IP address list of the local wireless access controller if the received discovery response message contains the IP address list of the wireless access controller, then, returning the step b), and otherwise, using the wireless access controller sending the discovery response message as a correlation wireless access controller.

Description

Wireless access controller discovery, association and configuration method technical field The present invention relates to a method for discovering and associating a wireless access controller (AC) and an AC configuration and associating method, in particular to dividing a network into multiple virtual subnets and configuring a preferred AC and a backup AC for each virtual subnet The AC priority configuration is formed to make the wireless access point (AP) associate with the appropriate AC in the network according to the configured priority. Background technique Thin AP, namely "thinAP", is relative to fat AP (fatAP). A thin AP simplifies the functions of an AP and needs to be used in conjunction with a wireless access controller (AC). The APs involved in the present invention are all thin APs, but for the sake of convenience, they are all referred to as "APs" for short. AC discovery means that the AP obtains the ACIP address list including the IP addresses of one or ...

Problems solved by technology

This method of discovering ACs sends association requests to all AC IPs at the same time, and does not distinguish the priority of ACs obtained in several ways. If there is more than one AC in the network, it is not guaranteed that the AP will associate to the desired AC
