Re: [IPFIX] IE for Reliability Extension


Hi Sujay:

Sorry it's taken me a while to get back onto IPFIX things.

I see that Juergen sent you an email on 21 April, suggesting that
you simply request IANA to add some new IE definitions to their
IPFIX IE Registry.

Reading your draft now, I agree with Juergen.  The draft simply
says "we need a new information element to say whether or not
the counter fields in the Reliability Statistics and Exporting
Process Statistics Option Templates are valid, or not."

It doesn't seem to me that you need more than the new IE, your
'reliabilityReasonCode.'  However, I'd like to see some discussion
of that on the IPFIX list.  For example, does the name tell us
what it actually means?  Would 'reliabilityCountersValid' be
any better?  Can it be implemented effectively?  Do others agree
that it would be useful?

Concerning the draft itself, I have a few editorial comments:
- MAYBE isn't an RFC 2119, that should be in lower case
- IE 239 is already allocated, the next free number is 277

I'm copying this to the list to see what others think of this.

Cheers, Nevil

Re: [IPFIX] IE for Reliability Extension

Thanks Nevil for the feedback.

Yes, I would agree for a more appropriate name change.

Sometime, when I last floated an email asking for responses as to who
has implemented Reliability Optional Template , there was IMO no
response, (??)

On the reason for the new IE, I do not see any disagreement from the list.

Whether it can be resolved without using a new IE is the question, and
I would welcome any proposals in the list.

Best Regards,
-Sujay

[IPFIX] FW: DISCUSS: draft-ietf-ipfix-mediators-problem-statement

Editors and Chairs,

Please address the issue raised by Sean in his DISCUSS. 

Thanks and Regards,

Subject: DISCUSS: draft-ietf-ipfix-mediators-problem-statement 

Discuss:
#1) The SECDIR review pointed out that the trust model needs to be
explained.   Atsushi suggested that there were two scenarios and they
should probably go in the follow-on framework document.  If that is the
case, then a normative reference is needed to point from the trust model
text/section to that particular section in the framework document.
However, the -06 of draft-ietf-ipfix-mediators-framework does not seem
to include this text.  Is it going to be included or is the trust model
going to be included in problem-statement?

[IPFIX] Gen-ART review of draft-ietf-ipfix-mediators-problem-statement-09

I have been selected as the General Area Review Team (Gen-ART) reviewer
for this draft (for background on Gen-ART, please see
http://www.alvestrand.no/ietf/gen/art/gen-art-FAQ.html).

Please resolve these comments along with any other Last Call comments
you may receive.

Document..........:  draft-ietf-ipfix-mediators-problem-statement-09
Reviewer..........:  Christian Vogt
Review date.......:  May 7, 2010
IESG Telechat date:  May 6, 2010

Summary:  This draft is ready for publication as a Informational RFC.

This document identifies scalability problems with modern flow-based
measurement, which are due to increasing traffic volume as well as
increasing measurement requirements complexity.  The document motivates
IPFIX mediation as a solution, and it gives a set of examples where this
solution applies.  The document also analyzes the disadvantages of IPFIX
mediation, which constitute the cost for better scalability.

I believe the document is ready for publication.  The document is easy
to read, concise, and well-structured.

Hi Dan, and Chairs,

The issues are being discussed in another mail.

I am wondering non-technical issue that problem statement 
needs normative reference to framework.

Can you try to reformulate this, I cannot really understand what you
mean.

Re: [IPFIX] FW: DISCUSS: draft-ietf-ipfix-mediators-problem-statement


Hi Dan, and all,

In IETF last call, the SECDIR review pointed out that the trust model
for mediator needs to be explained. At that time, I explained about my
thought included in framework draft.

In IESG review, Sean pointed out two comments; the current framework
draft is not enough explanation, the problem statement document needs
the normative reference to the framework draft.

With regard to framework document, thanks to Brian great suggestion, I
am preparing next version including trust model in security
consideration section. Please see the following sub-section 9.3.
http://www.nttv6.net/~akoba/draft-ietf-ipfix-mediators-framework-07-01.html#anchor24

With regard to including normative reference to framework, I have
one question. By definition, the goal of problem statement is to explain
the issues that should be resolved in a series of documents made
afterward, i.e., framework. It is starting point.
Thus, already the problem statement described the issues about the trust
model. In my opinion, it is enough as problem statement level.

Even so, normative reference is necessary?
Does it need to wait for framework draft?
If framework has normative reference to its protocol, does it need to
wait protocol draft moreover?

I would like to avoid long discussion about it, I will follow your and
IPFIX chairs' opinion.
