OSADL Academic Works Vol. 4: Concept of a Centralized User Configuration (CUC) in Time-Sensitive Networking (TSN) for Industrial Use Cases


As a standardized communication technology, Ethernet is a fundamental component in industrial automation. However, standard Ethernet is still unable to cover automation technology with hard real-time requirements. Meeting the continually growing communication needs will require a uniform, manufacturer-independent communication network for real-time applications and best-effort data traffic. Therefore, the Time-Sensitive Networking (TSN) working group of the IEEE standardization authority is extending existing Ethernet standards to allow for real-time communication.

One of the configuration models defined by TSN is the centralized model. It provides information on communication requirements and available network resources centrally, so it is well-suited for complex use cases. It includes the Centralized Network Controller (CNC), Centralized User Configuration (CUC) and User/Network Interface (UNI) that handles communication between the CNC and CUC.

For the time being, the centralized model still lacks a coherent configuration process that takes the UNI into account. This book presents a solution to this shortcoming. Furthermore, the centralized model is compared to an alternative model with a distributed approach. It concludes that the centralized model is suitable for real-time applications with stringent low-latency requirements, while the distributed model offers greater flexibility when latency requirements are less stringent. The current development of a merged model aims to blend the advantages of both models and increases the potential of TSN for industrial applications.

About the author

Martin Polster graduated from the Friedrich-Alexander University Erlangen-Nuremberg with Master of Science degrees in Information & Communications Technology and in Computer Science in 2019. As part of his studies, he spent a semester abroad at Harvard University in Cambridge, USA, where he designed an evidence-based software package for the health care sector. He also holds a Bachelor of Engineering degree in Electrical Engineering and a Bachelor of Science degree in Industrial Engineering. During his studies, Martin began his career as a Development Engineer at Siemens AG in Erlangen where his focus was on hardware-related software for embedded systems. Among other things, this stimulated his interest in network communication for industrial products which, in turn, inspired this work.
