LNI 4.0 Testbed Edge Configuration Implementation View
The testbed Edge Configuration was established to prepare the standardization in the context of the manufacturing industry with respect to the emerging edge computing technology. The testbed does not address edge computing technology in itself but focuses on edge configuration. For this purpose, con-cepts will be developed, practically implemented and validated. The results and experiences will be made available to the standardization activities to feed them into the further or new development of standards. From an architectural point of view, the testbed Edge Configuration is based on a layered architecture as shown in Figure 1:
Figure 1. Layered architecture of the proposed testbed Edge Configuration
The focus of the testbed Edge Configuration is on the configuration of the interaction between the field, edge and edge management layer. Currently there does not exist a suitable standard for this focus and the testbed will develop proposals for this aspect. Based on the functional primitives including parameter sets in the functional view, this document (implementation view) will provide a framework for formal REST-API interface specifications that can be directly implemented on IT relevant protocols like HTTP, MQTT or OPC UA. This formal specification shall be provided in form of JSON-based data models, objects and semantics.
