Method for controlling wireless mesh network with wireless access controller

Abstract

The invention discloses a method for controlling a wireless mesh network with a wireless access controller, relating to the field of communication. The method comprises the following steps that: (a) a first mesh node device in an accessed state collects MAC (Media Access Control) addresses of at least one second mesh node device; (b) the first mesh node device transmits a first MAC list containing the collected MAC addresses to the wireless access controller; (c) the wireless access controller queries the MAC addresses allowed to access the wireless access controller in the first MAC list based on prestored configuration information; (d) the wireless access controller transmits a second MAC list containing the queried MAC addresses to the first mesh node device; and (e) the first mesh node device establishes point-to-point links with the second mesh node devices corresponding to all the MAC addresses in the second MAC list. The accessed state means that the mesh node device is registered to the wireless access controller.

technical field [0001] The invention relates to a control method of a wireless grid network equipped with a wireless access controller in the communication field, in particular to a control method of a wireless grid network utilizing a thin AP framework. Background technique [0002] The existing mesh nodes are based on the fat AP framework, and all wireless physical layer and link layer logic (including mesh path discovery and path selection algorithms) are implemented in one network element. Moreover, its path discovery and path selection algorithms are not uniform, some are proprietary algorithms (based on the link layer), and some are standard algorithms (802.11s based on the link layer, routing algorithms based on the network layer OSPF, RIP, ISIS, etc.).

Problems solved by technology

Moreover, its path discovery and path selection algorithms are not uniform, some are proprietary algorithms (based on the link layer), and some are standard algorithms (802.11s based on the link layer, routing algorithms based on the network layer OSPF, RIP, ISIS, etc.)

[0003] Existing mesh node devices are implemented based on the fat AP architecture, so deployment and management are complex

[0004] Moreover, when discovering and selecting paths, regardless of using a private algorithm or a standard algorithm, each mesh node needs to participate in path discovery and selection calculations. Therefore, each mesh node needs to know the entire network topology. The requirements for mesh node equipment The higher the cost, the higher the cost

Moreover, when the network reaches a certain scale, the amount of calculation is large, and routing oscillation is prone to occur

[0005] Moreover, the path discovery and path selection algorithms of mesh nodes based on the fat AP architecture have poor scalability. When changing the path discovery algorithm and path selection algorithm, all mesh nodes need to be upgraded
