IIC 3-Tier IIoT System Architecture The edge tier collects data from the edge nodes, using the proximity network. The architectural characteristics of this tier, including the breadth of distribution, location, governance scope and the nature of the proximity network, vary depending on the specific use cases. The platform tier receives, processes and forwards control commands from the enterprise tier to the edge tier. It consolidates processes and analyzes data flows from the edge tier and other tiers. It provides management functions for devices and assets. It also offers non-domain specific services such as data query and analytics. The enterprise tier implements domain-specific applications, decision support systems and provides interfaces to end- users including operation specialists. The enterprise tier receives data flows from the edge and platform tier. It also issues control commands to the platform tier and edge tier. The proximity network connects the sensors, actuators, devices, control systems and assets, collectively called edge nodes. It typically connects these edge nodes, as one or more clusters related to a gateway that bridges to other networks. The access network enables connectivity for data and control flows between the edge and the platform tiers. For example, it could be a corporate network, an overlay private network over the public Internet or a 4G/5G network. Service network enables connectivity between the services in the platform tier and the enterprise tier, and the services within each tier. It may be an overlay private network over the public Internet or the Internet itself, allowing the enterprise grade of security between end-users and various services.

Mapping Between a Three-tier Architecture to the Functional Domains

IIC Gateway-Mediated Edge Connectivity and Management Pattern The local network may use different topologies as described below: In a hub-and-spoke topology, an edge gateway acts as a hub for connecting a cluster of edge nodes to each other and to a wide area network. It has a direct connection to each edge entity in the cluster allowing in-flow data from the edge nodes, and out-flow control commands to the edge nodes. In a mesh network (or peer-to-peer) topology, an edge gateway also acts as a hub for connecting a cluster of edge nodes to a wide area network. In this topology, however, some of the edge nodes have routing capability. As result, the routing paths from an edge node to another and to the edge gateway vary and may change dynamically. This topology is best suited to provide broad area coverage for low-power and low-data rate applications on resource-constrained devices that are geographically distributed. In both topologies, the edge nodes are not directly accessible from the wide area network. The edge gateway acts as the single entry point to the edge nodes and as management point providing routing and address translation. The edge gateway supports the following capabilities: Local connectivity through wired serial buses and short-range wireless networks. New communication technologies and protocols are emerging in new deployments. Network and protocol bridging supporting various data transfer modes between the edge nodes and the wide area network: asynchronous, streaming, event-based and store-and-forward. Local data processing including aggregation, transformation, filtering, consolidation and analytics. Device and asset control and management point that manages the edge nodes locally and acts an agent enabling remote management of the edge nodes via the wide area network. Site-specific decision and application logic that are performed within the local scope.

IIC Layered Databus Architecture This architecture provides low-latency, secure, peer-to-peer data communications across logical layers of the system. It is most useful for systems that must manage direct interactions between applications in the field, such as control, local monitoring and edge analytics. Smart machines use databuses for local control, automation and real-time analytics. Higher-level systems use another databus for supervisory control and monitoring. Federating these systems into a “system of systems” enables complex, Internet-scale, potentially-cloud-based, control, monitoring and analytic applications. A databus is a logical connected space that implements a set of common schema and communicates using those set of schema between endpoints. Each layer of the databus therefore implements a common data model, allowing interoperable communications between endpoints at that layer.
