Hi Tom,

Thank you very much for your comments!

Regarding GIST, please note that NSIS is mentioned as candidate, based on the comments of IESG and IAB on APONF improvements. These comments were provided after rejecting the first APONF BOF request.

We will take your comments in considerations and the discussions that we will have in Toronto when updating the 02 version of the problem statement draft.

Best regards,
Georgios

Onderwerp: Re: [Openv6] Comments on     draft-karagiannis-aponf-problem-statement-02

I did look at the architecture document while I was preparing my note,
and verified that it dealt with more specific detail than what I
proposed. That detail is what I was happy to see removed from the
Problem Statement.

It seems to me that this draft should either reference
draft-tremblay-aponf-gap-analysis or else the discussion of GIST should
be dropped from the Problem Statement. A third possibility is to merge
draft-tremblay-aponf-gap-analysis into this document, but that may be
taking the Problem Statement too far into solution space.

Tom
