EFFICIENTLY HANDLING RETAINED MESSAGES IN A SYSTEM WITH BRIDGED MESSAGE BROKERS - A simplified explanation of the abstract

  • This abstract for appeared for US patent application number 17828723 Titled 'EFFICIENTLY HANDLING RETAINED MESSAGES IN A SYSTEM WITH BRIDGED MESSAGE BROKERS'

Simplified Explanation

The abstract describes a method for handling retained messages in the context of Internet of Things (IoT) messages. In this method, a first message broker receives a subscription request from an IoT device, specifying a topic filter. The first message broker then checks a shared data structure with a second message broker to find any retained messages that match the topic filter. If there are any matching retained messages, the first message broker retrieves them from a shared data store and provides them to the IoT device.


Original Abstract Submitted

Methods, systems, apparatuses, and computer-readable storage mediums are described for handing retained messages among brokers of Internet of Things (IoT) messages. In an example system, a retained message coordinator of a first message broker receives an indication of a subscription specifying a topic filter from an IoT device. The retained message coordinator identifies, from a data structure shared by a second message broker, a retained message set for a topic within a scope of the topic filter. The retained message coordinator retrieves the retained message set from a shared data store, and provides the retained message set to the IoT device.
