Connectivity Framework 7: Connectivity Standards
7 CONNECTIVITY STANDARDS
This chapter lists the prominent connectivity standards for the framework and transport layers, using the assessment template defined in chapter 6, so that the standards can be understood in the context of IIoT needs. As additional standards are identified, they should be added to this list. The assessment template allows us to capture and describe the technologies in a uniform and objective manner.
Figure 7-1 summarizes the prominent IIoT connectivity frameworks and transports. It shows connectivity frameworks that have originated in an industry agnostic manner for generalpurpose use. The dotted boxes show the connectivity standards that have originated in certain industry verticals with a specific application focus that has applicability across multiple industries. Some connectivity frameworks define their own transport protocols( e. g. DDS, OPC-UA), and in the diagrams those are shown without any gap between the framework and the transport layer boxes. Others( e. g. Web Services, oneM2M) rely on general-purpose transport protocols. The network( IP) and lower layers( wired and wireless) are also shown for completeness, but are outside the scope of this document.

Figure 7-1: IIoT connectivity standards. Dotted boxes show the connectivity standards( e. g. oneM2M, OPC-UA) that have originated in respective industry verticals( e. g. telecommunications, manufacturing) to provide enabling features for those industries, and also offer an application focus that is applicable to multiple industries. Others( e. g. DDS, Web Services) have originated in an industry agnostic manner for general-purpose use, and are applied in multiple industries for many different kinds of application areas. Transports that are specific to a framework layer are shown without any spacing between the framework and the transport layer boxes.
