IEEE standards for deterministic Ethernet communication with a synchronized time base.

TSN stands for Time-Sensitive Networking and refers to a family of IEEE 802.1 standards for deterministic, time-critical Ethernet communication. Key building blocks include time synchronization, traffic shaping, per-stream filtering/policing, and mechanisms for reliability and low latency. For automotive data logging and sensor/ECU communication, TSN is especially relevant when Ethernet must be not only fast, but also time-deterministic.
