Embodiment

[0062] Such as figure 1 As shown in FIG. 2 , it is a flowchart of a method for performing load balancing of a wireless local area network by a wireless access controller adopted in this embodiment. The wireless local area network includes several wireless access points, several wireless access controllers and several wireless terminals; the load balancing process includes two parts: fast decision and slow decision. The quick decision is made based on the environment when the terminal was first launched. Slow decision-making is made by checking the connection status of all terminals at regular intervals. It generally includes two steps:

[0063] (1) When the wireless terminal starts to associate, the wireless access controller AC performs load balancing processing for the current wireless terminal according to the information collected at that time; or

[0064] (2) The wireless access controller AC checks the load conditions of the wireless access points AP associated with a...

Abstract

The invention discloses a method for balancing wireless local area network loads by a wireless access controller, and the wireless access controller receives information of a wireless terminal actively reported by a wireless access point (AP) when the wireless terminal in the wireless local area network sends a Probe Request message to the wireless AP. The method is characterized by comprising the following steps: (1) when the wireless terminal begins to associate, the wireless access controller (AC) performs load balancing treatment on the current wireless terminal based on the currently collected information; or (2) the wireless AC checks the load conditions of wireless AP associated with all on-line wireless terminals at frequent intervals and performs load balancing treatment based on the load conditions. The method in the invention can better cope with the condition that wireless network topology changes abruptly and has good actual load balancing effect.

Description

technical field [0001] The invention belongs to the field of embedded wireless communication, and specifically relates to a method for realizing load balancing of a wireless local area network by using a wireless access controller and a wireless access point to cooperate with each other, in particular to a method for real-time collection of the surrounding area of ​​a wireless controller. The wireless environment data, and the method of load balancing for decision-making based on it. Background technique [0002] In recent years, the number of wireless access points has grown rapidly, and the convenience and high efficiency of wireless networks have made it popular rapidly. Currently, wireless access points are deployed in many public places. Due to the limited signal coverage of wireless access points, in order to receive wireless signals in every corner, people need to deploy many wireless access points. In this way, there will be a problem: since each access point in th...
