Adaptive mode switching method for wireless Mesh network

Abstract

The invention discloses an adaptive mode switching method for a wireless Mesh network. The method comprises steps: a portal point periodically operates a certain address command in the ping internet; in the case of ping interoperability, the portal point is switched in a MPP (Mesh Portal Point) mode, and the default gateway routing entry of the original point is deleted; in the case of unable ping interoperability, the portal point is switched in a MP (Mesh Point) mode; after a message is sent to the portal point, whether a network bridge exit is consistent with the default gateway IP address is checked; in the case of consistency, the MPP is switched in the MP mode, and the default gateway routing entry is added; the MP is switched in the MPP mode, and the default gateway routing entry is deleted; and the MP is switched in the MP mode, whether the default gateway IP in a gateway list is the same as the default gateway IP address through a bridge interface is compared, if not, the default gateway through the interface is deleted, and a new default gateway is added. An adaptive switching function is realized in a WMN network multi-gateway environment is realized, the robustness of the network is added, and surfing experience of the user is enhanced.

Description

technical field [0001] The invention belongs to the technical field of distributed networks, and in particular relates to an adaptive mode switching method of a wireless MESH network. Background technique [0002] Node devices in traditional WLAN networks are generally divided into gateway devices and common access devices according to different deployment locations and functions; and different hardware platforms can be used differently. If the backbone equipment in the network fails and has not been repaired manually, the service cannot continue to be provided in its coverage area. In the traditional large-scale network engineering deployment, the AC-AP mode is adopted, and the access controller AC provides functions such as user access control and roaming switching. Users access the network to obtain resources by connecting with the AP. If an AP or AC device fails, all users within its coverage area will be unable to communicate. Therefore, the traditional wireless netw...

Problems solved by technology

[0004] The purpose of the present invention is to provide an adaptive mode switching method for a wireless MESH network, which aims to solve the problem that most of the existing routers and gateway devices do not realize the adaptive mode switching function, and when the equipment fails, the network will be paralyzed, resulting in All devices as the default gateway cannot connect to network resources, and the network lacks robustness
