Industrial network of the next generation are expected to have augmented capabilities and intelligence within the information-centric paradigm supports. In this paper, a 7-level network protocol is devised with the service-oriented architecture of a 3-tier hierarchical model. Large-scale decentralized resources are abstracted into virtual physical devices first as a primary service provider. Knowledge and services are defined and formulated using ontology models in a modeling layer. Context awareness is used to align attributes and to intensify couplings between different decentralized resources by decomposing and aggregating internal ontology models. Knowledge, services and context make large-scale industrial networks more cognitive and feasible. Through the optimal composition of elementary services, decentralized applications are implemented in the service-oriented architecture. An informational architecture can finally be established using incomplete measurement data and reasoning for large-scale industrial networks.
