Cloud Edge Interaction Protocol Detection System for Distribution IoT Based on Metadata Definition

With the rapid construction of the distribution IoT, various devices are continuously promoted and applied. In order to standardize the communication between the devices of various suppliers and the distribution cloud master station system, State Grid Corporation of China has developed a cloud edge interaction protocol. For cloud and edge interaction protocol detection, this paper uses the Microservices framework and combines the flexible and extensible characteristics of the protocol to develop a detection system based on $B / S$ architecture. This system supports flexible definition of detection cases, can simulate various communication scenarios, meet batch detection requirements, and has good universality and scalability. The practical application results indicate that the system can effectively identify devices that do not comply with the protocol, thereby ensuring the legitimacy of the equipment’s access to the distribution IoT.
