Have you struggled to effectively apply conventional connectivity solutions to your Industrial Internet of Things (IoT) application? Do you feel like you're re-inventing the wheel every time you have to deal with multiple states as you add new applications? Do you end up creating your own custom application-level protocols? Will your connectivity solution be flexible enough to accommodate future requirements, data types, and staffing changes?

The Industrial IoT introduces new requirements for the velocity, variety, and volume of information exchange. Connectivity must be real-time and secure, and it must work over mobile, disconnected, and intermittent links. It must efficiently scale to handle any number of things, each of which may have its own unique requirements for information exchange, such as streaming updates, state replication, alarms, configuration settings, initialization, and commanded intents. These requirements are above and beyond the requirements commonly handled by conventional connectivity solutions designed for static networks.

This white paper describes a connectivity architecture model for the Industrial IoT and shows how the Data Distribution Service (DDS) messaging standard can address the unique requirements of the Industrial IoT. Concepts will be illustrated using a scalable Industrial IoT application architecture that shares real-time data between mobile devices and the cloud and provides browser-based access from thin clients. The optimal use of web-sockets technology is also described in the architecture overview.
