Body 
The IEEE 802.1 Working Group would like to thank ITU-T Study Group 13 for the
information provided in liaison statement 208
https://www.ieee802.org/1/files/public/docs2024/liaision-itu-t-SG13-LS208-DetermNetwrking-0824.pdf
on request for feedback on work items related to deterministic networking in
SG13.

As a reminder, the IEEE 802.1 Time-Sensitive Networking (TSN) Task Group (TG)
(and its ancestor, the IEEE 802.1 Audio Video Bridging (AVB) TG) was formed
several years ago to provide solutions for use cases requiring time and/or
mission critical data communications, i.e., deterministic communications. The
solutions the IEEE 802.1 TSN TG is actively developing and has already
developed (i.e., the tools of the TSN toolset) address various aspects required
for deterministic data communications and provides solutions for the
requirements of various use cases. Furthermore, the use cases are expanding.

The most prominent use cases are addressed by dedicated profile specifications
developed in joint effort with experts of the area of the given use case. We
have published the following profile specifications:

- IEEE Std 802.1BA-2021 “Audio Video Bridging (AVB) Systems”
- IEEE Std 802.1CM-2018 “Time-Sensitive Networking for Fronthaul”, as amended
by IEEE Std 802.1CMde-2020 “Enhancements to Fronthaul Profiles to Support New
Fronthaul Interface, Synchronization, and Syntonization Standards”
