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 .
