Joint Evaluation of TSN Topology and Scheduling Algorithm in Autonomous Driving Scenarios
摘要
This study proposes and constructs two typical topology architectures based on operational domains and functional domains for time-sensitive network (TSN) applications in automotive Ethernet, conducting comparative analyses of their latency performance and scalability. Building on this foundation, we formally model and evaluate three scheduling algorithms: queue isolation, window mapping, and injection time planning. Through experiments on the Open-planner platform across multiple scenarios, these results demonstrate that the window mapping algorithm excels in multi-period and high-load scenarios; the queue isolation algorithm is suitable for large-scale deployment; while the injection time planning algorithm exhibits strong robustness in complex and extreme high-traffic environments. These findings provide valuable references for automotive Ethernet topology design and scheduling algorithm selection.
