Load balancing access method for wireless local area network

Abstract

The invention discloses a load balancing access method for a wireless local area network. A wireless access controller predicts a future flow variation tendency by statistics of a historical flow within a period of time in the past; furthermore, the flow threshold value of an AP is set with the help of the bandwidth of a current wired terminal network; and thus, balancing access of a terminal between the APs can be controlled. A background server is unnecessary in the load balancing access method for the wireless local area network disclosed by the invention; the implementation manner is relatively simple; furthermore, the system resource cost is low; the flow threshold value of the AP is dynamically set to be H according to a practical network environment; the load balancing access method is relatively flexible; and the load balancing effect is better.

Description

technical field [0001] The invention relates to the field of communication and wireless local area network networking, and more specifically, to a load balancing access method of a wireless local area network. Background technique [0002] WLAN (Wireless Local Area Network) refers to the application of wireless communication technology to interconnect computer equipment to form a network system that can communicate with each other and realize resource sharing. In a WLAN network environment, an extended service group system consists of one or more basic service groups and distribution systems connecting these basic service groups, and each basic service group includes a wireless access point device. The extended service set is distinguished by ESSID (extended service set identification number), and the AP (wireless access point) is distinguished by BSSID (basic service set identification number). The terminal obtains the information of the extended service group and the basi...

Problems solved by technology

[0007] After careful analysis, it can be found that the above method has the following disadvantages: Although the distributed method in method 1 does not require a background server and can improve the fault tolerance of load balancing, the algorithm and software implementation of the distributed system are relatively complicated, and each AP of the system In order to maintain its own balanced information base, the system resource overhead is large

In method 2, it is judged whether the wireless access point achieves load balancing by setting a fixed upper limit value, but the upper limit value is not dynamically set according to the actual network environment, which is not flexible enough and the load balancing effect is not ideal

Most of the existing load balancing methods do not make full use of the historical traffic of wireless access points to predict the traffic at the next moment, thereby helping to achieve load balancing between wireless access points
