Folks,

Here are the draft minutes from Monday's meeting. If you have any
comments or questions feel free to ask.

Regards,
Karen

NTP Meeting IETF 68, Prague, Czech Republic
1300-1500, 19 March 2007 
Minutes from Dave Marlow

o Administrivia - Karen O'Donoghue chaired the meeting,

Mailing list, blue sheets, scribes, agenda bashing.
No jabber scribe was appointed, 

o Charter and Milestones updates  - Karen O'Donoghue

Karen provided a history of the NTPv4 work noting it was the 
the second anniversary of this Working Group.  

o NTPv4 Specification - Karen O'Donoghue

Dave Mills has provided a rewrite of the NTP4 protocol 
04-draft.  The editors are rolling this into a revised ID
which has addressed a number of issues including: 
  *Expanded abstract
  *SNTP overview
  *Server discovery overview
  *Expanded clarification of IPv6 changes to the NTPv4 header format.
  *Clarification of the differences between the document 
   and the reference code.
  *Numerous editorial changes and clarifications

The issues that still remain to be worked are:
  *Clarification of the draft's normative and informative material.
   -Plan is to make protocol normative and the algorithms informative.
  *Approach to handle Autokey material.
  *Voiced consensus from the community. 

Mark Townsley, the Working Group's AD, challenged the Working Group
to finish the NTPv4 Protocol document.  This will help enable
the start of TICTOC to look at a new problem space.  Jim Martin,
one of the NTPv4 Protocol document editors was asked to complete
the work on the protocol and send in the 05-draft with all issues
addressed to the ID list by the end of the week.  Mark asked for 
at least five volunteers to read the document and post their 
comments to the Working Group list within the first two weeks of 
the release of the 05-draft.  Eight participants volunteered 
upon which the plan was agreed to make this a Working Group Last 
Call.  The eight volunteers are:
 Malcolm Airst
 Stewart Bryant 
 Steve Chen
 Greg Dowd
 Chris Elliott
 Heiko Gerstung
 Laurent Montini 
 Yaakov Stein

Mark promised to continue the effort and get the resulting draft 
to IETF Last Call as soon as possible,  Pat Cain, this Working 
Group's Security advisor, is ready to assist as well.

o NTPv4 MIB - Chris Elliott

Chris discussed the NTPv4 MIB 01-draft that was released just prior
to the meeting.  The updated draft provides:
  *Clarifications to indicate that the MIB is not limited to use by
servers 
   -Clients can also use the MIB.  
  *Added the ntpSrvControl group and moved into it:
   -ntpSrvHeartbeatInterval
   -ntpSrvNotifBits
  *Added ntpSrvStatusTime to some notifications.
  *Modified ntpSrvStatusTime:
   -Previously Was a Counter64 object, now a 0 or 16 byte string 
    containing the NTP 128-bit date format. 
   -Counter64 definition left in, but commented out, to show the 
    complexity of defining the supporting objects.

Chris went over the issues which needed further work:
  *Need to modify ORGANIZATION and CONTACT-INFO
   -CONTACT-INFO still needs correct information
  *ntpAssocIndex and ntpAssocID need better descriptions.
  *Consider instrumenting a leap second object.
  *Consider notification for leap seconds.
  *Consider whether ntpSrvTimeDistance should be in the info group or
status.
  *Consider whether ntpSrvStatusTime should be 64-bit date format.
   -Dropping the top 32 bits of era and bottom 32 bits of precision. 
  *Consider defining TCs for types that might be useful elsewhere.
  *Consider notification for when synched.
   -Currently there is notification for when not in synch.
  *Reduce conformance/compliance requirements for NTP and SNTP clients.

In addition, based on discussions at the meeting, an update is needed
to the the security section of the NTPv4 MIB 01-draft which states that 
all objects are read-only since there are now two read-write objects.

Chris indicated that resolutions to the current issues would be resolved
soon and that the 02-draft of the MIB would be posted soon.  Karen 
expressed the need for people to post to the Working Group list with
any issues and also to express support with 02-draft if it is
sufficient.
