AB - Recently, Time-Sensitive Networking (TSN) has gained increasing attention as a promising solution to handle the growing sensor data and complex control demands in In-Vehicle Networks (IVN).
In particular, the Time-Aware Shaper (TAS) defined in IEEE 802.1Qbv is regarded as a key mechanism for ensuring time determinism. However, TSN performance is highly affected by network topology, making topology-aware analysis essential for IVN design. This paper investigates the impact of topology variation on time determinism in an IEEE 802.1Qbv-based IVN environment. To this end, a baseline Dumbbell topology reflecting a Zonal Architecture was designed, and additional Spoke links were incrementally attached to the central switch. OMNeT++ and NESTing simulations were conducted to evaluate performance metrics. The results indicate that increasing the number of Spoke links mitigates central bottlenecks by distributing traffic, leading to higher throughput and reduced delay and packet delay variation. These findings confirm that topology configuration directly affects TAS-based time determinism and provide useful reference data for future IVN design.
