Load Balancing Method for Wireless Access Points

Abstract

A load balancing method for wireless access points includes that AC (access control) sets up a client and APs (access point) correspondence list, detects flow of the current AP such as ratio accounting for total flow and the current load number so as to control whether the APs can respond to access of the client requesting access or not when receiving a new client access request, and thus load of all APs controlled by the AC is balanced. The APs set a buffer time and online time interval of the clients after started so as to prevent APs overload caused by access of many clients instant the APs are started. The clients are distributed in many APs of the integral network in balance, the problem that an existing method only depends on signal strength to judge whether the clients access or not is solved, integral performance of the network is remarkably improved in balance, network transmission speed is higher and user experience is more comfortable.

Description

technical field [0001] The present invention relates to the field of wireless local area network (WLAN, Wireless Local Area Network), in particular to the adjustment of a wireless access control device (AC, Access Control) for a client to access a wireless access point (AP, Access Point) to realize wireless access point load balancing method. Background technique [0002] With the development of wireless network technology, multi-carrier technology and multi-antenna technology are used in wireless networks to support higher peak rates and minimum transmission delays, thereby improving the performance of the entire network. However, load imbalance often exists, and this phenomenon seriously affects network performance. It often happens that multiple APs are deployed in the same area, but multiple clients are mounted on a certain AP, while there are fewer clients on other APs. [0003] WLAN network technology allows users to enjoy the fun of free movement. When a wireless c...

Problems solved by technology

The method of simply considering the AP signal RSSI can easily lead to a large number of clients connecting to the same AP. Since these clients share the wireless medium, the network throughput of each client will be greatly reduced.

[0004] Therefore, it is difficult to guarantee the performance and bandwidth of wireless users completely relying on the IEEE standard 802.11 protocol of the existing WLAN network

Because the protocol leaves the wireless roaming decision to the client, but the protocol does not restrict the algorithm for the client to determine roaming
