The maximum working capacity ratio refers to a ratio of a maximum data transmission quantity of the first router to a preset data transmission quantity in a preset time period, and the minimum working capacity ratio refers to a ratio of a minimum data transmission quantity of the first router to the preset data transmission quantity in the preset time period.
The mesh network architecture refers to that a router is connected with a root node, the root node is connected with child nodes, and the child nodes are connected with the root node and all the child nodes. The architecture for updating the mesh network may be a switching root node, a switching router, a channel used between the switching root node and the router, or a network device which is detected as a new child node and is added into the mesh network.
In one embodiment, there are various scenarios for updating the architecture of the mesh network, including but not limited to the following:
