An icon shown as a green parallelogram representing the Communications View

The Communications View describes the communications protocols necessary to provide interoperability between Physical Objects in the Physical View. Each triple from the Physical View has been mapped to one or more data dictionary standards, referred to by the CVRIA as an information layer standard, and one or more communications profiles identify the communications protocols necessary to transport data described by an information flow.

The CVRIA NITSA Communications Model and Communications Profiles are based on the Open System Interconnection (OSI) Model, the NTCIP Framework, and DSRC/WAVE Implementation Guide. The diagram below shows how the Communications Model for the Connected Vehicle Reference Implementation Architecture (CVRIA) and National ITS Architecture (NITSA) can be related to other communications models, including the traditional OSI Model, the ITS Station Reference Architecture defined in ISO 24102 family of standards, as well as the NTCIP Framework. The 8 layers of the CVRIA NITSA Communications Model are described below:

In addition, the Security Plane identifies standards that specify policies and system-to-system authentication, and encryption of data across one or more layers of the communications stack.

The communications profiles reflect likely implementation choices have been developed and assigned, where applicable, to triples. The communications profiles have been developed following closely the naming practices of the OSI (Open Systems Interconnection) Model.
