Networking is such that a communication device distributed network is not limited to a single or one-to-one communication connection. The distributed networking may form a dynamic network of communication devices involved in a current scenario (home scenario, industrial manufacturing scenario, etc.).

In a dynamic network of networking, the communication capability and the service capability of each communication device can be effectively managed. When any communication equipment in the networking has service requirements, the communication equipment can provide information of the communication equipment required by the service at any time through the network of the distributed soft bus, and the establishment of a service channel is supported.

4. Transmission of

The transmission technology of the distributed soft bus can provide the transmission capability of service data for any communication equipment in the current scene. The transmission technology of the distributed soft bus can abstract the business data and the service quality (quality of service, qoS) and provide proper transmission service according to the network load and the capability of the communication equipment. The transmission technology can ensure the transmission quality of multiple services in the whole distributed network while ensuring the communication appeal of a single service.

The Harmonyos distributed soft bus abstracts the transferred data into four data models: messages, bytes, files, and streams. Based on different data models, the distributed soft bus can pertinently construct a proper transmission scheme and Qos strategy. Wherein, the message can be used for transmitting short data (such as control instructions) with extremely high real-time and reliability requirements; bytes, which can be used for basic service data transmission with low requirement on time delay; the file can be used for transmitting and synchronizing the file between communication devices, and a larger transmission bandwidth is required, but the real-time requirement is not high; the stream can be used for transmitting audio and video streams, and requires high bandwidth and low time delay.

Under the existing networking method, the new communication equipment needs to be networked with all communication equipment in the current scene, and the networking time is too long, so that the use of users is affected. At the same time, in order to ensure keep alive between communication devices, the new communication device also needs to keep constant connection with all communication devices in the network and periodically transmit data. This can result in consumption of a significant amount of unnecessary resources and power consumption by the communication device, as well as unnecessary waste of air interface resources.

Therefore, the embodiment of the application provides a networking method which can be used for communication equipment, and can realize a networking mode with small time delay and small occupied resources under the condition of large quantity of communication equipment in the networking.

Fig. 2 is a schematic diagram of a scenario where the networking method provided by the embodiment of the present application is applicable. The scene can be an intelligent family scene or a mine automatic acquisition scene. In mine automation acquisition scenarios, there are typically hundreds of racks on the coal face. When a new communication device needs to be networked, the new communication device needs to be networked with hundreds of brackets respectively, which is too long in time consumption and also needs to consume a large amount of resources. Fig. 2 shows a networking scenario for smart home. It is understood that the plurality of first communication devices are located in the same local area network, and the plurality of first communication devices may be various intelligent terminal devices. The plurality of first communication devices has completed the networking, illustratively and is divided into first virtual subnets. When the second communication device accesses the current local area network as a new communication device, the second communication device only needs to be networked with a master communication device of the plurality of first communication devices, and only needs to be always connected with the master communication device. Thus, the time required by networking of the new communication equipment can be reduced, and resources required by keep-alive are saved.

The master communication device stores device information of the second communication device. The second communication device stores device information of the plurality of first communication devices. Therefore, after networking is completed, the first communication device and the second communication device can realize service interaction according to actual needs.

In some embodiments, multiple virtual subnets may be divided, where each virtual subnet has a primary communication device, and when a second communication device may be often connected to a specific primary communication device according to actual needs, the second communication device may be often connected to one primary communication device or may be often connected to multiple primary communication devices, which embodiments of the present application are not limited in this respect.

On the other hand, in order to keep alive, the second communication device only needs to keep constant connection with the main communication device, and does not need to keep constant connection with all communication devices in the virtual sub-network, so that occupation of resources can be effectively saved.
