Technical field
The present invention relates to wireless local area network (WLAN) system (WLAN; Wireless Local Area Network) load balancing field; More specifically; Relate to cluster management and the system of dynamic load leveling implementation method and a kind of cluster management and dynamic load leveling between the wireless controller (AC, Access Point Controller).
Background technology
WLAN is Wireless Local Area Network, WLAN.Different with common Ethernet (cable LAN); WLAN mainly uses media such as radio wave or IR to carry out the transmission of signal, with reference to accompanying drawing 1, except that the Internet; Wlan system by the point of termination station wlan system by point of termination station (STA; Station), access point (AP, Access Point) and wireless controller (AC, Access Point Controller) are formed.
The wireless lan (wlan) technology is based on 802.11 medium access control standards, this standard definition the wave point between point of termination station (STA) and the access point (AP).Perfect along with the development of wireless technology and 802.11 medium access control standards; Wireless lan (wlan) is disposed on a large scale now; The scale of single wireless lan (wlan) is also very big, comprises hundreds of in the common single wireless lan (wlan) to several thousand access points (AP).
In order to manage control these access points (AP) and wireless lan (wlan) business datum flow better, introduced the notion and the wireless controller (AC) of Centralized Wireless LAN.In Centralized Wireless LAN, by the configuration of controlled in wireless management control access point (AP) and the business datum flow of point of termination station (STA).Connect through the CAPWAP agreement between access point (AP) and the wireless controller (AC), the CAPWAP agreement is to be specifically designed to controlled in wireless and configured protocols by the Internet organization prescribed.In addition, in Centralized Wireless LAN, concentrate the business datum flow of forwarding and leading subscriber usually by wireless controller.
See also accompanying drawing 1, the CAPWAP protocol definition control and management passage and the data forwarding passage between wireless controller (AC) and the WAP (AP), management control access point (AP) and management forwarding user's business datum flow respectively.Because the disposal ability and the finite capacity of separate unit wireless controller can be disposed many wireless controllers in some large-scale wireless lan (wlan)s, be used to share management control access point and concentrate the task of transmitting service traffics.
In the deployment of larger Centralized Wireless LAN; Can share management control access point and concentrate the task of transmitting service traffics through disposing many wireless controllers (AC); But how to let the load between the wireless controller evenly distribute and backup mutually, industry is not also seen the processing method of system.
A kind of process that connects STA entering wireless network at mobile radio terminal is disclosed among the Chinese patent CN200810112188.3; Wireless Centralized Controller AC calculates the load of corresponding wireless access point AP; If corresponding wireless access point AP load is overweight; Refuse the access request of this portable terminal so, utilize portable terminal STA to select the characteristics of adding automatically at a plurality of WAPs (AP), realize the load balancing between the WAP to a certain extent.But this method can not solve the unbalanced problem of task load between the wireless controller (AC) in extensive Centralized Wireless LAN.
A kind of method is disclosed among the Chinese patent CN200810222269.9; This method is to obtain each item network performance parameter of each wireless controller in the network of place at WAP (AP); Then respectively according to each item network performance parameter; Network performance to each wireless controller carries out analyzing and processing, obtains the integrated network performance parameter of each wireless controller.WAP (AP) is according to the integrated network performance parameter of each wireless controller; Select to insert the wireless controller that an integrated network performance reaches preset standard; Thereby realize the load balancing between the wireless controller among the WLAN to a certain extent; Can make full use of Internet resources is that client is provided services on the Internet, and improves network performance.But this method does not consider to belong to the dynamic change factor of WLAN, increases the task load that can cause corresponding wireless controller suddenly such as terminal use's quantity of being managed below some wireless controllers and increases the weight of.
A kind of method is disclosed in the Chinese patent 200780014125.8, this method be need not under the situation of complex modifications to regulate the transmitted power level of AP beacon message in case reduce congested, but need not regulate the transmitted power level of AP data traffic channels.This method realizes the load balancing between the WAP to a certain extent.But similar with the problem that patent [200810112188.3] solves, can not solve the unbalanced problem of task load between the wireless controller (AC) in extensive Centralized Wireless LAN.
Therefore, we need take all factors into consideration the characteristics of Centralized Wireless LAN, propose the method for a kind of cluster management and dynamic load leveling.
