Abstract

The present application relates to the technical field of data transmission, in particular to a message format negotiation method and device. The method is applied to an edge device, and the method includes: the edge device sends a connection request message to a cloud platform; the edge device receives a confirmation connection request message sent by the cloud platform, wherein the confirmation connection request message The message format supported by the cloud platform is carried in the extended payload; the edge device sends the collected data to the cloud platform based on the message format. Using the message format negotiation method provided by this application, the edge device can directly complete the negotiation of the message format during the process of establishing a network connection with the cloud platform, without modifying the program code on the edge device for adaptation.

Description

technical field [0001] The present application relates to the technical field of data transmission, in particular to a message format negotiation method and device. Background technique [0002] Message Queuing Telemetry Transport (MQTT) is a message protocol based on the publish / subscribe paradigm under the ISO standard (ISO / IEC PRF 20922). It works on the TCP / IP protocol family and is a publish / subscribe message protocol designed for remote devices with low hardware performance and poor network conditions. MQTT is a client-server based message publish / subscribe transport protocol. The MQTT protocol is lightweight, simple, open and easy to implement. These characteristics make it widely applicable. In many cases, including constrained environments such as machine-to-machine (M2M) communication and the Internet of Things (IoT). It is used extensively in sensors communicating via satellite links, medical devices that occasionally dial, smart homes, and some miniaturized de...
