Abstract
Time-Sensitive Networks (TSN) enhance standard IEEE 802.1Q Ethernet devices with real-time and time-aware capabilities. The forwarding of time-critical frames is done according to a so-called Gate Control List (GCL) schedule via the timed-gate mechanism introduced in IEEE 802.1Qbv. Most TSN scheduling mechanisms impose that all devices in the network must have the TSN capabilities related to scheduled gates and time synchronization. However, this is often an unrealistic assumption since many distributed applications use heterogeneous TSN networks with legacy or off-the-shelf end systems that are unscheduled and/or unsynchronized.
