Application of TSN

TSN has various application areas, verticals. Profile standard has been or is being specified for some of them to describe which TSN standards to use and how. A TSN profile selects features, options, configurations, defaults, protocols, and procedures of bridges, end stations, and LANs to build a bridged network for the given TSN application. Further application cases of TSN are described below.

Audio Video Bridging (AVB Systems)

The IEEE Std 802.1BA-2011 Audio Video Bridging (AVB) Systems standard describes how to build a bridged network to meet the requirements of audio-video streams. 802.1BA is successfully deployed for various applications today, e.g., professional audio and video studios, and automotive infotainment.

Mobile fronthaul networks

Fronthaul connects a cellular network’s radio equipment to their remote controller. The IEEE Std 802.1CM-2018 Time-Sensitive Networking for Fronthaul approved draft standard describes how to build a fronthaul bridged network to meet the stringent requirements of the fronthaul flows.

Industrial automation

IEC and IEEE 802 has a joint work to describe the use of TSN for industrial automation. The IEC/IEEE 60802 TSN Profile for Industrial Automation will describe guidelines for the selection and the use of IEEE 802 standards and features in order to be able to deploy converged networks to simultaneously support operations technology traffic and other traffic. A flyer gives an overview of the potential of TSN to industrial automation, i.e., TSN is an enabler of Industry 4.0.

Automotive networks

TSN is an enabler of the application of Ethernet networks within a car as summarized in this flyer. This tutorial provides further information on the application of Ethernet to automotive.

Utility

A white paper is being prepared to explain how TSN could be used in a utility operational network.
