Implications of Layered Databus Architecture for Control and Optimization

By Valentijn de Leeuw

ARC Report Abstract

IIC’s Industrial Internet Reference Architecture

Layered Databus Architecture IIIC1.JPGThe Industrial Internet Consortium's (IIC’s) Industrial Internet Reference Architecture (IIRA) is part of a series of technical documents describing that organization's view on the Industrial Internet of Things (IIoT). The document describes a reference architecture for an IIoT system derived from an architectural framework based on the ISO/IEC/IEEE 42010:2011 standard for systems and software engineering. The IIRA develops four viewpoints relative to: the business, usage, functions, and implementation; plus a number of cross-viewpoint system characteristics and concerns. A recent guest blogpost on ARC Advisory Group's IIoT View-points blog nicely summarizes the benefits of IIRA V1.8 and enumerates the updates compared to the previous version.

The Layered Databus Organized as System of Systems

This latest version discusses an additional architectural pattern: the layered databus organized as a system of systems. Applying such an architecture would have potential implications for:

  • the protocols used in the control layer

  • integration with the operations and business layers

  • use of aggregated, vs. non-aggregated Big Data for edge-, fog-, and cloud-based analytics, and

  • the scope of cloud-based analytics and optimization provided by integrating value chain networks.
