TSN (Time-Sensitive Networking)

Also known as: Time-Sensitive Networking, IEEE 802.1 TSN

TSN is a set of IEEE 802.1 standards that add deterministic latency, bounded jitter and high availability to standard Ethernet through time synchronisation (802.1AS), scheduled traffic (802.1Qbv), frame pre-emption (802.1Qbu) and frame replication (802.1CB). 3GPP integrates TSN with 5G in Release 16 by modelling the 5G system as a TSN bridge, so that URLLC bearers can carry industrial control traffic end-to-end.

TSN in context

Telecom security is written into standards from 3GPP, GSMA, ETSI, IETF and ITU-T. Understanding which body owns which specification, and how they interlock, is essential for both design and audit work.

To place TSN in the wider telecom-security picture, review 3G, 3GPP, 4G, 5GNR, 6G and ADSL — each entry cross-references back to this page so you can walk the topic in either direction.
