This is a useful informative document. One comment: In the discussion of PTP timestamps, it might be worth talking about the correctionField. This field is intended to be used to make various types of corrections to the PTP timestamps, including the ability to add sub ns resolution. Doug ________________________________ From: ntp <ntp-bounces@ietf.org> on behalf of internet-drafts@ietf.org <internet-drafts@ietf.org> Sent: Monday, February 24, 2020 5:39 AM To: i-d-announce@ietf.org <i-d-announce@ietf.org> Cc: ntp@ietf.org <ntp@ietf.org> Subject: [Ntp] I-D Action: draft-ietf-ntp-packet-timestamps-08.txt A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Network Time Protocol WG of the IETF. Title : Guidelines for Defining Packet Timestamps Authors : Tal Mizrahi Joachim Fabini Al Morton Filename : draft-ietf-ntp-packet-timestamps-08.txt Pages : 21 Date : 2020-02-24 Abstract: Various network protocols make use of binary-encoded timestamps that are incorporated in the protocol packet format, referred to as packet timestamps for short. This document specifies guidelines for defining packet timestamp formats in networking protocols at various layers. It also presents three recommended timestamp formats. The target audience of this document includes network protocol designers. It is expected that a new network protocol that requires a packet timestamp will, in most cases, use one of the recommended timestamp formats. If none of the recommended formats fits the protocol requirements, the new protocol specification should specify the format of the packet timestamp according to the guidelines in this document. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-ntp-packet-timestamps/ There are also htmlized versions available at: https://tools.ietf.org/html/draft-ietf-ntp-packet-timestamps-08 https://datatracker.ietf.org/doc/html/draft-ietf-ntp-packet-timestamps-08 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-ietf-ntp-packet-timestamps-08 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
