hi xiaoming, jukka, john, ....

process-wise:
i see some value in a 'what things group X/Y/Z cares about' discussion.
i see much more value in a 'this is the complete issue list and here
are the commonalities/divergences between different people' discussion
(as I think we succeeded in doing with the 3 QoS drafts in Vienna).

we should start that discussion on the list now and maybe we can do
some further merging in Minneapolis (depending on what else is exciting
to do on Monday).

on a scoping point:
between the lines I detect some concern that there is a danger that
some of the mobility discussion may turn into some kind of 'Mobile-NSIS'
project with a life of its own. it's my opinion that this shouldn't
happen (and in fact isn't likely to happen). instead, what I think we
are talking about here is analysis work which will feed into defining
the functionality that is required in the basic NSIS protocols themselves
(just like we have analysed security and so on). that protocol design 
work - which is going on now - is a potential eager consumer of this 
mobility work; at the moment, the mobility impact on protocol design
has been driven mainly by instinct rather than solid thought, and it
is time to put that instinct on a much firmer foundation.

on the technical points:
i have a pile of drafts to read...

cheers,

r.

Hi all,

I went through all mobility-related drafts and I basically agree with you 
about the common issues.

To me it seems that we have pretty much identified the main issues, and it
is time to move on now. I would suggest that we gather one single draft
about the implications of mobility, routing, multi-homing and routing
changes/repair into one single WG draft. This draft would be used as a
"requirements"-type of document as the design of NTLP continues, to check
that the design fits specific environments (mobile, routing changes,
multi-homing). The document would also include the backgrounds for certain
issues, not just repeat requirements already mentioned in the requirements
draft. In addition, the document would be a reference for the current and
future NSLP documents: what you need to take into account when you design
an NSLP?

I would include in this document the issues Seong-Ho already mentioned,
and, the issue with refresh timers, and encapsulation issues because many
LMM protocols do this. I would leave out resource discovery (since, at
least in a mobile environment, CARD is doing this), and pre-reservations,
because these are more of a trick and very special scheme to deal with
mobility and resources. Moreover, I wouldn't want the document to have
discussions on how to implement things - the NTLP and NSLP documents will
do this eventually, if not already.

Thus, it would be a draft that documents the current understanding of the
issues between mobility/routing/multi-homing and resource signaling.

The authors of the various mobility drafts listed by John could meet in
Minneapolis, e.g. on Sunday, after the reception, to discuss these issues
before the actual NSIS WG meetings. We could, for example, try to agree on 
an initial set of issues to discuss in the draft, and assign responsible 
section editors, and an overall editor.

Any comments?

Regards,
Jukka
