The load balancing server is a server for load distribution. And the obtained service requests are distributed to the servers of the tenant instances which are actually operated in a balanced manner through the load balancing server, so that the response speed of the whole system is ensured. The message server is a server for receiving, transmitting and forwarding messages. Distributed node clustering, fast and low-delay message routing, and single clustering supports routes of ten million scales. The application server is a server for actually running the tenant instance and is generally divided into a plurality of nodes.
Referring to fig. 1, the data transmission method of a peer node provided in this embodiment includes:
and step 110, receiving target equipment data sent by the load balancing server.
The target device is a specific device such as a printer and a face recognition instrument, and the target device data is data sent by the device, such as temperature data sent by a temperature measurement device. The equipment sends the service request containing the equipment data to the load balancing server, and then the load balancing server distributes all the service request information to each message server in a balanced manner according to the actual state of each message server.
The data of the specific theme of the target equipment is published to the message server through the load balancing server, the message server transmits the theme data to the application server subscribed with the theme, and the theme data message is transmitted to the specific node in all service nodes running the same tenant instance in the application server through a preset transmission mode of the message server. And the target tenant instance is the service content actually run by the target tenant. For example, there are 3 service nodes running the same tenant instance a, which are respectively Node1, Node2 and Node3, and these three nodes are peer nodes. The tenant instance a acquires the data of the device Z by subscribing, and when the device Z transmits data, only one Node among the Node1, the Node2, and the Node3 may receive the data of the device Z, and a specific Node that receives the data is determined by a preset sending method.
