A New Internet-Draft is available from the on-line Internet-Drafts
directories.
This draft is a work item of the Network Time Protocol Working Group of the IETF.
Title : Network Time Protocol Version 4 Protocol And Algorithms Specification
Author(s) : J. Burbank, et al.
Filename : draft-ietf-ntp-ntpv4-proto-07.txt
Pages : 108
Date : 2007-7-25
The Network Time Protocol (NTP) is widely used to synchronize
computer clocks in the Internet. This document describes NTP Version
4 (NTPv4), which is backwards compatible with NTP Version 3 (NTPv3)
described in RFC 1305, as well as previous versions of the protocol.
NTPv4 includes a modified protocol header to accommodate the Internet
Protocol Version 6 address family. NTPv4 includes fundamental
improvements in the mitigation and discipline algorithms which extend
the potential accuracy to the tens of microseconds with modern
workstations and fast LANs. It includes a dynamic server discovery
scheme, so that in many cases specific server configuration is not
required. It corrects certain errors in the NTPv3 design and
implementation and includes an optional extension mechanism.

In the body type:
"FILE /internet-drafts/draft-ietf-ntp-ntpv4-proto-07.txt".
NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
