Embodiment Construction

[0019] The technical solutions of the present invention will be described in detail below, but the protection scope of the present invention is not limited to the embodiments.

[0020] Such as figure 2 As shown, the MQTT protocol communication method for realizing multiplexing in this embodiment, the specific steps are as follows:

[0021] Step 1. Establish several TCP channels at the transport layer, and the same group of MQTT clients communicate with the MQTT proxy server through the same TCP channel, that is, make a one-to-many mapping relationship between several MQTT clients and TCP channels of the same group; The one-to-many mapping relationship is dynamically generated according to the login (online) and offline of the MQTT client;

[0022] Step 2, log in to the MQTT proxy server on the MQTT client, and obtain the mapping relationship between the MQTT client and the TCP channel;

[0023] Step 3, when working, when the MQTT proxy server needs to forward messages, firs...

Abstract

The invention discloses an MQTT protocol communication method and system for realizing multiplexing. The method comprises: establishing a plurality of TCP channels; acquiring a mapping table of a login client and a TCP channel when an MQTT client logs in a proxy server; searching for the TCP channel corresponding to the MQTT client in the mapping table through an MQTT client ID when receiving andsending messages; then acquiring all message content of the TCP channel; and finally realizing multiplexing of the TCP channel. According to the invention, the problem that a star network topologicalstructure of Lora and Zigbee communication accesses an Internet of Things protocol is solved, so that the MQTT proxy server is compatible with a conventional MQTT protocol at the same time, and equipment supporting a standard MQTT protocol can also be normally accessed.

Description

technical field [0001] The invention belongs to network communication technology, and in particular relates to an MQTT protocol communication method and system for realizing multiplexing. Background technique [0002] MQTT (Message Queuing Telemetry Transport) is a messaging 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. [0003] For the current MQTT protocol, there is a one-to-one correspondence between the MQTT channel and the TCP channel, resulting in the coupling of the MQTT protocol and the transport layer, which has the advantages of low protocol overhead, tolerance to unstable networks and fault recovery, and support for large concurrent connections. [0004] However if figure 1 As shown, in the prior art, there is a one-to-one correspondence between the...
