The piece that has been missing until recently is the ability to reliably connect the edges, the frontiers of the data network.
Systems already exist that understand what actions to take based on the status of the remote device. However, communicating that status to the system has been a challenge, particularly if the network is constrained or if the device lacks the computational power required for traditional messaging. With MQTT the following components are just some examples of those that can communicate with each other and with other systems or applications: Smart energy meters Industrial control systems Satellite receivers Healthcare monitoring devices Sensors on everything from planes to trains to automobiles Usage of the MQTT protocol extends WebSphere MQ to tiny sensors and other remote telemetry devices that might otherwise be unable to communicate with a central system or that might be reached only through the use of expensive, dedicated networks.
Network limitations can include limited bandwidth, high latency, volume restrictions, fragile connections, or prohibitive costs. Device issues can include limited memory or processing capabilities, or restrictions on the use of third-party communication software. In addition, some devices are battery-powered, which puts additional restrictions on their use for telemetry messaging.
The MQTT protocol includes the following benefits: Extends connectivity beyond enterprise boundaries to smart devices Offers connectivity options that are optimized for sensors and remote devices Delivers relevant data to any intelligent, decision-making asset that can use it Enables massive scalability of deployment and management of solutions Solution overview With WebSphere MQ Telemetry, instrumented devices that are located anywhere in the world can connect to each other.
And with WebSphere MQ, they can connect to enterprise applications and web services. From the WebSphere MQ queue manager, the messages can be exchanged with other messaging applications. This coupling is achieved by introducing a message broker between the publisher and the subscribers Figure 2.
Figure 2. The publisher sends the message with an identifier that denotes its topic or subject area. The broker then distributes the message to all applications or devices that subscribe to that topic. Solution architecture The popularity of MQTT-based messaging stems from the simple way it allows information to be published or subscribed to, without needing to know who or what is sending or receiving the information.
This simplicity allows each message to be small in size, reducing demands on the network and on the remote monitoring devices from which many MQTT messages emanate. Figure 3. Typical system architecture with the WebSphere MQ Telemetry daemon for devices This connection makes it possible to minimize the number of concurrent channel connections on a WebSphere MQ queue manager.
The daemon also can be used to store and forward messages from other MQTT clients. WebSphere Application Server deployment. WebSphere Application Server components. Java virtual machine JVM. Web Container.
