Time-Sensitive Networking (TSN)

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. These extensions in particular address the transmission of very low transmission latency and high availability. Applications include converged networks with real-time audio/video streaming and real-time control streams which are used in automotive or industrial control facilities.
