- Intended status: experimental

6. NTS for PTP

(Karen in behalf of Martin)
- The NTS4PTP draft has been updated. While it does not yet contain all the planned content, many changes have been made. Some non-essential parts have been removed to simplify the protocol. Additionally, new chapters have been added addressing replay and spoofing protection.
- Overall, the document has been optimized, reducing the total number of pages. Furthermore, the draft has also been uploaded to the NTPWG GitHub repository.
