Main technical content: This standard takes edge computing gateways as the object and specifies the communication interface requirements for southbound heterogeneous device access and northbound unified access platforms. It supports seamless access of southbound devices of different types and brands, and constructs an intelligent protocol stack at the access layer, which includes protocol parsing and protocol normalization templates of different types, capable of adapting to different types of protocol access and parsing. For the northbound access platform, it stipulates the communication interface for information interaction between edge computing gateways and the platform, including communication methods, encryption methods, data types, data formats, encoding methods, and communication content, effectively reducing the difficulty and cycle of interface connection between southbound devices and northbound platforms.
