In this embodiment, the network may be an ad hoc network, which refers to a network combining mobile communication and a computer network, so as to implement flexible networking of network devices.

According to the embodiment of the application, after the network has entered a steady state, the master device election is not performed any more, so that the stability of the network is ensured, and stable service is provided for network devices in the network.
In this embodiment, if a role conflict notification returned by the network device in the second state based on the role notification message is received, the working state of the device is changed from the waiting state to the master role conflict state, where the second state is used to indicate the temporary master role state in which the selected temporary master device is located before the network enters the steady state.
In this embodiment, the role conflict notification carries default roles of the network device, identification information (for example, MAC address of the network device, etc.), hardware performance parameters (for example, device type, device serial number, device start time, CPU resource, memory resource, etc.), and the like, and the embodiment of the present application is not particularly limited.

In this embodiment, there are many methods for detecting that the network enters a steady state, for example, detecting that the user configures an administrator password or other configuration operations on the device, and the embodiment of the present application is not particularly limited.
In this embodiment, when the working role of the device changes from the default master role to the target master role, if a role notification message broadcast by a network device newly joining the network is received, a network opening notification is sent to the newly joining network device; if a master device discovery request broadcast by a network device of a newly added network is received, a nano-tube notification is sent to the newly added network device, so that the newly added network device establishes connection with the device based on the nano-tube notification to manage the newly added network device.
