A Practical Guide to Using the Industrial Internet Connectivity Framework
Of course, this design targets a future world
of vastly connected systems. There is a more
immediate question: “if I’m starting an IIoT
project, what should I use?” Next, we
present the IICF guidance and a simple tool
to navigate that guidance.
Have standards-defined Core Gateways
to all other connectivity core standards.
With that definition, the IIC experts
proceeded to define criteria, survey
standards and evaluate all the standards
against those criteria. The criteria definitions
alone are a huge contribution, beyond the
scope of this paper. They resulted in an
“Assessment Template” with deep analyses
of the six standards with greatest IIoT
traction: DDS, OPC UA, oneM2M, RESTful
HTTP, MQTT, and CoAP. The assessment

standard. This design scales linearly with the number of technologies, thus enabling a true Internet.
includes business, usage, functional and
implementation viewpoints. It is a unique
analysis of connectivity technologies for
industrial systems. In the end, the IICF
identified four of the six as potential core
standards: DDS, OPC UA, oneM2M, and
RESTful HTTP.
