Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0027] The invention mainly separates the LWAPP control tunnel and the data tunnel between the AC and the AP in the centralized control mode, and processes them separately by multiple different ACs. For this reason, the present invention introduces the concepts of control AC (CAC) and data AC (DAC), divides the AC into two groups of control AC and data AC, and each group includes at least one AC; wherein the control AC establishes a control AC with each AP Tunnel is responsible for all functions of the original centralized control mode except data forwarding, that is, establishing and maintaining control tunnels, managing the association status between APs and ACs, and managing connected clients. There can be any number of data ACs, which establish data...

Abstract

The invention discloses a wireless network control method and a wireless controller. The method comprises the following steps: dividing ACs (Access Controllers) in a wireless network into two groups, and determining that one group of ACs are control ACs and the other group of ACs are data ACs, wherein each group at least comprises one AC; synchronizing AP (Access Point) information and information of a client connected to the AP between the control ACs and the data ACs; using the control ACs to receive an on-line request transmitted by the AP and establish a control tunnel with the AP which transmits the on-line request; and using the control ACs to transmit address information of the data ACs to the AP, which transmits the on-line request, through the control tunnel, so that the AP which transmits the on-line request establishes a data tunnel with the data ACs according to the address information of the data ACs. The method and the wireless controller can enhance the data processing capability of the wireless network under a centralized control mode.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a wireless network control method and a wireless controller. Background technique [0002] In the networking of wireless networks such as WLAN and WIFI, it is generally implemented by a wireless access point (AP) and a wireless access controller (AC). In this AC+AP networking mode, the AP is a wireless transceiver device, which is responsible for converting the data received from the wired network (such as the Internet) into wireless signals for transmission, converting the received wireless signals into data and forwarding them to wired internet. The AC completes functions such as authentication / configuration / data forwarding of wireless users, and plays a role of centralized control. [0003] figure 1 It is a schematic diagram of the existing typical wireless network networking structure, such as figure 1 As shown, in the wireless network, one AC is connected ...
