We are happy to announce the updated version of the Industrial Internet Connectivity Framework (IICF), a foundation document that guides the building of an Industrial IoT (IIoT) connectivity architecture. The latest version of the IICF expands the connectivity guidance to include lightweight, resource-constrained machine-to-machine (M2M) devices often found at the edge of networks. The IICF defines an IIoT communications stack and a connectivity assessment template. It applies the assessment template to evaluate IIoT connectivity standards and provides guidance on selecting the right connectivity standard based on system requirements. The IICF connectivity reference architecture enables data sharing and interoperability across a diverse range of IIoT systems.
The IICF is a fact-based, consensus-developed document that provides a stable long-term foundation for IIoT interoperability. It offers helpful, practical, tangible guidance for requirements assessment, technology evaluation, and selection.
The updated IICF builds on the previous versions and provides updates and assessments for connectivity framework standards, including Open Platform Communications United Architecture (OPC UA), oneM2M, Lightweight M2M (LwM2M), Data Distribution Service™ (DDS) including the new DDS for Extremely Resource-Constrained Environments (DDS-XRCE) and DDS for Time-Sensitive Networking (DDS-TSN) specifications. The latest version of the IICF also includes updated diagrams and an expanded list of standards.
IICF authors include Rajive Joshi from RTI, Paul Didier from Cisco, Christer Holmberg and Jaime Jimenez from Ericsson, and Timothy Carey from Nokia. For more information and a complete list of contributing authors, please download the IICF from the IIC website.
