Method and device for transporting message

Abstract

The invention discloses a method and a device for transporting a message. A specific embodiment of the method comprises the steps of receiving the message released by a releasing client; finding a subscription client, wherein a theme of the message subscribed by the subscription client is consistent with the theme of the released message; detecting a value of a session cleaning identifier set on the found subscription client; in response to that the value of the session cleaning identifier set on the found subscription client is a false value, storing the message to a distributed system, and then sending the message stored in the distributed system to the found subscription client. According to the method and the device disclosed by the embodiment, a distributed-configuration message queuing telemetry transport service is realized, and the message congestion problem is solved.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of Internet technology, and in particular to a method and device for transmitting messages. Background technique [0002] MQTT (Message Queuing Telemetry Transport) is a known instant messaging protocol that has the potential to become an important part of the Internet of Things. The protocol supports all platforms, can connect almost all networked objects with the outside world, and is used as a communication protocol for sensors and actuators. [0003] Most of the currently available solutions are stand-alone MQTT services. The disadvantage of the stand-alone version of the MQTT service is that there is a single point of failure, and the stand-alone MQTT service cannot support more user connections and message sending. At present, the MQTT service adopted by some companies is implemented in a proxy mode, which only forwards MQTT messages to another message...

Problems solved by technology

[0003] Most of the currently available solutions are stand-alone MQTT services. The disadvantage of the stand-alone version of the MQTT service is that there is a single point of failure, and the stand-alone MQTT service cannot support more user connections and message sending.

At present, the MQTT service adopted by some companies is implemented in a proxy mode, which just forwards the MQTT message to another message queue. These message queues are shared, and the routing function that does not support wildcards is not a complete MQTT service.

At the same time, because the subscription function of MQTT does not support partitioning, this will cause messages subscribed to a topic to be processed independently by each connection (the messages received by each connection are exactly the same, and the messages received by each client cannot be achieved. different), there will be a problem of message congestion
