new nemo charter approved


Hi all,

After a discussion and some edits, the IESG has approved the
new charter for NEMO. Here are the changes:

1) Added the types of document (PS, Inf) for each deliverable.

2) Formulated the technical requirements of the different
cases using the speed and range of movements rather
than through the industry that uses them.

3) Changed the deliverables for the PMR and Automotive
case so that there's a rechartering step between the
approval of the requirements document and the solution
work. This does not apply to the Airliner solutions work,
however. It can proceed immediately.

4) A few editorial changes.

The reason for these changes were comments from the rest
of the IESG, in general attempting to make the charter more
precise and involve more checkpoints where the IESG or the
rest of the community can verify that we're going to the right
direction. Item 3 above is a change from what the WG initially
wanted, but was a necessary compromise to get the charter
approved.

Here's the new charter:

Re: new nemo charter approved


Dear Jari, all,

Thanks for the assistance in this and the feedback.

I do have a comment about the "speed of movement". I don't get at all
why the speed would be a selective criteria, the frequency of movement
would, on the other hand. The others criterias are of course the size
of the network on the move, and the use case itself. I do think that
the major difference is in the use and not the speed.

The May 2007 milestones are too optimistic since we are already well
engaged into April.

Thierry.

Speed is one of the criteria, among others. Speed and distance of the
movement
does matter. For instance, a fast/far moving object gets easier into a
situation
where it has to tunnel to a geographically far away destination. Frequency
does matter, too, but in a different way. High movement frequency implies
a lot of updates to home agents and correspondent nodes.

I will take another look before sending the final charter to the
secretariat. Is there a suggestion? I don't think we should move
milestones too much, however.

I do agree with that, but I think just mentioning "speed" is too
implicit and doesn't help. A better wording would mention "type of
media" and topologically distant subsequent points of attachment. To
me, the aircraft use case is very similar to the (international)
high-speed train use case (unfortunately no one from this industry
never showed up in our discussion), but still, even the French TGV
which beat the world record on track last week (at 576 km/h) is still
falling short from approaching the speed of airliners. So, "speed" is
not exactly the right criteria though I understand what you mean.

RE: new nemo charter approved

Jari/Thierry

A couple relevant examples:

- Within the last couple weeks the FCC (not the FAA!) continued the ban
on cell phone usage in the US on aircraft.  The reason remains the same;
the number of cell tower hops per minute that an on aircraft user
generates while on a call creates excessive route changes in the
cellular network.

- When using most geo-satellites, the beams have a relatively small
overlap and an aircraft has only perhaps 10 minutes from acquiring a new
satellite signal until the previous one is lost.  When this beam switch
is initiated, the aircraft's ground station usually moves thousands of
miles and that often involves instantaneous jumps between continents.

- On some routes, an aircraft travels more or less down the dividing
line between two geo-satellite beam areas, this often results in the
aircraft bouncing back and forth between these beams every few minutes.

Take care
Terry

NEMO route optimization requirements

Along with Will Ivancic and Terry Davis, I just submitted an initial
Internet-Draft that discusses requirements for NEMO route optimization
in order to be useful for aeronautical and space networking.  We think
this can be developed further by both the aeronautics community and IETF
in the near future, and is intended to feed into a NEMO working group
document to satisfy the new charter item:

  May 2007 Submit -00 draft on Route Optimization Needs for Aircraft and
  Spacecraft Deployments.

The document is currently available at:
http://roland.grc.nasa.gov/~weddy/shared/nemo/draft-eddy-nemo-aero-reqs-00.txt
and should be up on the IETF server soon.

We look forward to comments, constructive criticism, and questions on
this draft, and will be present at the next IETF meeting Chicago to
discuss it, if desired.  This is simultaneously being evaluated by
aviation-specific standards bodies, and we plan to relay any changes
proposed there through NEMO and vice-versa.

I think the confusion is that the *new* charter hasn't been put on the IETF
webpage yet, but in the mailing list archives you can find a copy of it
that Jari sent out recently, where route optimization makes up the
majority of the milestones:
