“…Satisfiability Modulo Theories (SMT) is a well-developed and widely used approach for this problem [13]- [16]. Latest research [17] proposes window-based heuristic scheduling which relaxes flow isolation but still provides real-time guarantee for flows. However, flow routes must be provided for scheduling whereas recovering link failures requires finding both the alternative routes and schedules.…”

“…Due to expensive bandwidth overhead, network designers also tend to minimize the amount of TT flows. The realistic systems evaluated in recent studies [17], [29], [31] indicate that there can be less than twenty TT flows in relatively small TSN use cases.…”

“…Other window-based scheduling algorithms were presented in [5]- [8], [34], [35]. In [34], [35], the authors implemented their scheduling algorithms with no synchronization requirement for end systems. However, the prerequisite is that all non-terminal nodes must be synchronized with each other.…”

“…Although the presented model in [5] and [6] has enhanced the solution space compared with full-isolated windows, the TT window overlapping was not optimized with the targeted latency deadlines. Moreover, the algorithms were implemented with node-based design without considering the offset difference between the same priority windows in the adjoining nodes [5], [6], [34], [35]. Zhao et al [7] proposed an analytical model based on completely isolated TT windows by considering the offset difference between the same class windows in adjoining nodes.…”

“…However, the computation time needed to generate the schedule varies from some minutes to a few hours, depending on the network complexity (number of nodes/switches, number of flows, etc.). In [26], a novel heuristic scheduler is introduced for the so-called Stream Reservation (SR) classes introduced by the Ethernet Audio Video Bridging (AVB) standards and now rolled into the IEEE 802.1Q-2018 standard. It provides shorter schedule computation times, i.e., in the order of seconds, but it cannot guarantee zero jitter transmissions.…”
