It’s time: Time Sensitive Networking and Deterministic Networking
By Aaron Frank and Mike Southworth
An industry perspective from Curtiss-Wright Defense Solutions
Time Sensitive Networking (TSN) is a set of Ethernet networking capabilities used to transmit time-sensitive data across standard Ethernet networks. Originally, TSN grew out of the IEEE 802.1 standard working groups on Audio Video Bridging (AVB) to make sure that independent networks streams for audio and video data arrive at the correct times to ensure synchronization. AVB also requires guaranteed delivery throughput and latency to avoid problems like missing video frames. Today, TSN features new 802.1 standards and enhancements that go beyond AVB time-synchronized streaming and can support low-latency, precision data delivery over Ethernet for a broader set of industrial, automotive, aerospace, and other real-time communications applications.
