Deadline-Aware Online Scheduling of TSN Flows for Automotive Applications

The time-sensitive networking (TSN) set of standards allows to support on the same channel the dif- ferent kinds of traffic flows that are typically found in automotive scenarios. This article proposes the introduc- tion of online earliest deadline first-based scheduling in TSN to provide support for event-driven real-time traffic. The proposed approach, called deadline-TSN, is an online approach, and therefore, unlike other approaches in the literature, it does not require complex offline schedule cal- culations. Moreover, deadline-TSN is able to uniformly deal with real-time periodic and event-driven traffic flows. This article presents deadline-TSN and provides both worst- case response time analysis and simulative assessments in realistic automotive scenarios.
