Time-Sensitive Networking (TSN) is a set of standards under development by the Time-Sensitive Networking task group of the IEEE 802.1 working group.^[1] The TSN task group was formed in November 2012 by renaming the existing Audio Video Bridging Task Group^[2] and continuing its work. The name changed as a result of the extension of the working area of the standardization group. The standards define mechanisms for the time-sensitive transmission of data over deterministic Ethernet networks.

The majority of projects define extensions to the IEEE 802.1Q – Bridges and Bridged Networks, which describes virtual LANs and network switches.^[3] These extensions in particular address transmission with very low latency and high availability. Applications include converged networks with real-time audio/video streaming and real-time control streams which are used in automotive applications and industrial control facilities.
