Future in-vehicle networks will use Ethernet as their communication backbone. As many automotive applications are latency-sensitive and have strict real-time requirements, a key challenge in automotive network design is the deterministic low-latency transport of latency-critical Ethernet frames. Time-sensitive networking (TSN) is an upcoming set of Ethernet standards, which address these requirements by specifying new quality of service mechanisms in the form of different traffic shapers. One of these traffic shapers is the burst-limiting shaper (BLS). In this paper, we evaluate whether BLS is able to fulfill these strict timing requirements. We present a formal timing analysis for BLS in order to compute worst-case latency bounds. We use a realistic automotive Ethernet setup to compare BLS against Ethernet AVB and Ethernet following IEEE 802.1Q.
