Software-Defined Networking (SDN) is a relatively new technology that enables network operators to have very tight but also very flexible, policy-defined control over traffic flows in the network. Using SDN in Time-Sensitive Networking (TSN) offers network operators not only control of the network but also manageability of key network parameters such as latency, throughput, and reliability. In this paper, we discuss the state-of-the-art research related to SDN-enabled TSN networks, present system requirements for time-sensitive heterogeneous wireless distributed software-defined networks, and derive a system architecture. The proposed system architecture not only enables large distributed heterogeneous TSN networks, but also integration with other (legacy) systems, and network management by multiple operators.
