Draft of message to be sent after approval:
From: The IESG <firstname.lastname@example.org> To: RFC Editor <email@example.com> Cc: The IESG <firstname.lastname@example.org>, <email@example.com>, firstname.lastname@example.org Subject: Re: Informational RFC to be: draft-mills-sntp-v4-01.txt The IESG has no problem with the publication of 'Simple Network Time Protocol (SNTP) Version 4 for IPv4, IPv6 and OSI' <draft-mills-sntp-v4-01.txt> as an Informational RFC. The IESG would also like the IRSG or RFC-Editor to review the comments in the datatracker (https://datatracker.ietf.org/public/pidtracker.cgi?command=view_id&dTag=10845&rfc_flag=0) related to this document and determine whether or not they merit incorporation into the document. Comments may exist in both the ballot and the comment log. The IESG contact person is Thomas Narten. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-mills-sntp-v4-01.txt The process for such documents is described at http://www.rfc-editor.org/indsubs.html. Thank you, The IESG Secretary
Technical Summary This document describes the Simple Network Time Protocol (SNTP) Version 4, which is a subset of the Network Time Protocol (NTP) used to synchronize computer clocks in the Internet. SNTP can be used when the ultimate performance of the full NTP implementation described in RFC-1305 is not needed or justified. SNTP Version 4 clarifies certain design features of NTP which allow operation in a simple, stateless remote-procedure call (RPC) mode with accuracy and reliability expectations similar to the UDP/TIME protocol described in RFC-868. The only significant protocol change in SNTP Version 4 is a modified header interpretation to accommodate Internet Protocol Version 6 (IPv6) (RFC-1883) and OSI (RFC-1629) addressing. However, SNTP Version 4 includes an anycast mode and a public-key based authentication scheme designed specifically for broadcast and anycast applications. The authentication scheme extension is described in another RFC. Until a definitive specification is published, these extensions should be considered provisional. In addition, this memo introduces the kiss-o'-death message, which can be used by servers to suppress client requests as circumstances require. Working Group Summary An IETF WG for NTP is about to be chartered, as a follow-up to a BOF that was held at the November, 2004 IETF. At the BOF, it was decided that this document should be pubished as is (as an Informational RFC), and that the document would be used as a basis for developing a standards track version of NTP in a WG (in the process of being formed). Protocol Quality This document has been reviewed for the IESG by Thomas Narten, and there are multiple implementations. IESG Note This RFC is not a candidate for any level of Internet Standard. The IETF disclaims any knowledge of the fitness of this RFC for any purpose and in particular notes that the decision to publish is not based on IETF review for such things as security, congestion control, or inappropriate interaction with deployed protocols. The RFC Editor has chosen to publish this document at its discretion. Readers of this document should exercise caution in evaluating its value for implementation and deployment. See RFC 3932 for more information. The reader should be aware that the IETF has formed an NTP Working Group to develop a Standards Track version of NTP version 4. This document will serve as input to that effort.
