SDN based wireless local area network load balancing method and device the same

Abstract

The invention discloses a SDN based wireless local area network load balancing method and device the same. The method includes monitoring and listening to the wireless route loading wave of the access point in the basic service set; when the rush time of the access point in the basic service set exceeds the rush time threshold of the preset route, the access point is the overload access point; the overload access point reports the overload information to the SDN control device, the SDN control device switches the mobile terminal of the access point coverage region to the access points that have not reported the overload information. Therefore, the aforementioned SDN based wireless local area network load balancing method and device, can enhance the overall functionality of the network, thereby protecting the service quality of the users and enhancing the user experience.

Description

technical field [0001] The present invention relates to the technical field of wireless networks, in particular to an SDN-based wireless local area network load balancing method and device. Background technique [0002] Wireless Local Area Network (WLAN) has developed rapidly due to its advantages of mobility, networking flexibility and scalability. With the widespread deployment of WLAN and the popularity of smart terminals, a WLAN network often needs to serve a large number of users, because in the association phase, the MS only selects the target AP (Wireless Access Point) according to the size of the received signal strength (RSSI), and the The load status of APs will not be considered, which will lead to unbalanced load among APs, reduce the utilization efficiency of network resources, and affect the overall performance of the network. [0003] The load balancing technology of WLAN can effectively solve the problem of network congestion. By balancing the load differenc...

AI Technical Summary

Problems solved by technology

Load balancing based on the number of access users is mainly to achieve the purpose of load balancing by limiting the number of APs accessing MSs. The number of MSs associated with APs cannot truly and effectively reflect the current AP load status.

If a certain AP is associated with a large number of MSs at the current moment, but because the communication traffic of these MSs is very low, the load of the AP is also very low at this time, but the judgment based on the above criteria will have the opposite result

It is also one-sided to judge the load based on the amount of AP traffic, because when the operating rates of MSs are inconsistent, some APs may have light loads, but the time on the channel is occupied by a large number of low-speed MSs, resulting in intensified channel conflicts.
