The IESG has received a request from the Network Time Protocols WG (ntp) to consider the following document: - 'NTP Over PTP' <draft-ietf-ntp-over-ptp-05.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the last-call@ietf.org mailing lists by 2025-09-24. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document specifies a transport for the client-server and symmetric modes of the Network Time Protocol (NTP) which encapsulates NTP messages in messages of the Precision Time Protocol (PTP). This transport enables hardware timestamping in network interface controllers which can timestamp only PTP messages and enables delay corrections in PTP transparent clocks. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-ntp-over-ptp/ No IPR declarations have been submitted directly on this I-D.
