The IESG has received a request from the Network Time Protocol WG (ntp) to consider the following document: - 'The Network Time Protocol Version 4 (NTPv4) Extension Fields' <draft-ietf-ntp-extension-field-04.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 ietf@ietf.org mailing lists by 2015-09-01. 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 The Network Time Protocol Version 4 (NTPv4) defines the optional usage of extension fields. An extension field, defined in RFC5905, is an optional field that resides at the end of the NTP header, and can be used to add optional capabilities or additional information that is not conveyed in the standard NTP header. This document updates RFC5905 by clarifying some points regarding NTP extension fields and their usage with Message Authentication Codes (MAC). The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-ntp-extension-field/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-ntp-extension-field/ballot/ No IPR declarations have been submitted directly on this I-D.
