Time-Sensitive Networking (TSN) is a networking technology that represents an essential building block for the convergence of industrial, heterogeneous communication networks in the field of industrial automation. The provisioning of a context-agnostic high communication quality in a dynamic environment with heterogeneous requirements and shared network resources is the goal of the collaborative research center - SFB 1053 "MAKI - Multi-Mechanisms Adaptation for the Future Internet". The goal of this transfer project within the SFB 1053 is to enable switch models and programming architectures for Quality-of-Service control in Time-Sensitive Networks. Our aim is to enable a network resource optimization and fault tolerance for TSN applications built on top of dynamic SDN infrastructures using the concept of Transitions which is being developed within the SFB 1053. Transitions are to be understood here as reconfigurations of the programmable network infrastructure elements, e.g. switches, in such a way that Quality-of-Service criteria of the automation applications running over TSN are met. Results of this project will be shown through realizations of real-time functions of industrial applications using TSN.
