Description

Network configuration updating method with configuration stabilization mechanism Technical Field The present invention relates to mesh network technology, and more particularly, to a network configuration updating method with a configuration stabilization mechanism. Background Mesh networks (mesh networks) are a type of communication of data and control instructions between network nodes by means of dynamic routing. The network can keep the connection between every two nodes intact, when a certain node fails or fails to serve in the network topology, the architecture allows a new route to be formed by using a 'jump' mode, and then the message is sent to a transmission destination. When pairing and switching between node devices in a mesh network, packet transmission may fail due to environmental interference. However, even if pairing and handover are not successful, some node devices may misrecognize that the node device has been successfully connected to another node device, or misrecognize that the node device has not been connected to another node device. Such a situation causes inconsistency in the connection relationship between the node devices recorded in the assistance tables of the node devices, and causes an abnormality in the transmission of data.
