Dear Wes, Thank you for your comments.
Please see inline. Cheers, Med >-----Message d'origine----- >De : George, Wes [mailto:[email protected]] >Envoyé : mardi 4 décembre 2012 21:09 >À : BOUCADAIR Mohamed OLNC/OLN; [email protected]; [email protected] >Cc : [email protected] >Objet : RE: draft-boucadair-intarea-host-identifier-scenarios > >I've read this draft, and I think the use case list is >reasonably complete. > >However, it's really unclear to me what the value of this >draft might be in its current form, and what its intended >audience might be. Cataloging use cases is not all that >helpful by itself without an end goal in mind, and that end >goal is not clear from the draft. Med: The goal of this draft is what is described in Section 2: "The goal is to identify scenarios the authors are aware of and which share the same issue of host identification. This document does not include any solution-specific discussion. This document can be used as a tool to design solution(s) mitigating the encountered issues. Having a generic solution which would solve the issues encountered in these use cases is preferred over designing a solution for each use case. Describing the use case allows to identify what is common between the use cases and then would help during the solution design phase." Next updates of this draft will: * include a discussion section to assess whether the issue is valid for IPv4-only or it applies also for IPv6 * include a discussion text to clarify whether each use case is valid within one single administrative domain or not * include a discussion text to identify use cases which share the same requirements (this will help in designing the solution) * add additional use cases if any At given point in time we need to draw conclusions about the following: (1) are these use cases valid ones? (2) if this is a real technical problem, what the IETF can do to solve the issue? (3) if there is interest in this area, how to organize the work for the solution space. The scope is deliberately >very narrow and references other drafts that discuss some of >the surrounding issues with address sharing and unique >identifiers, and so there is very little text in each section >beyond a basic description. Even when you think of this in >terms of follow-on drafts such as a gap analysis or problem >statement or solution drafts, one wonders how useful it is to >spread this across multiple drafts. So why not simply >incorporate this list into one of the referenced general >drafts on host identification, such as nat-reveal-analysis and >then broaden that draft so that it considers and addresses the >other use cases as appropriate? Med: As I mentioned above, we don't want to include any solution-specific discussion to this draft. The text is shortened in purpose. > >Otherwise, I think that the draft needs to be much clearer >about the unique issues and considerations for each use case, >especially those that are somehow distinct from those covered >in nat-reveal-analysis so that it can serve as a better input >to any potential solutions addressing this problem. Med: Fully agreed. This will be added to the next rev of the draft. > >I also believe that if this draft is to remain a standalone >document, the authors need to make at least some attempt at >discussing security and privacy considerations here, even if >it is mainly to refer the reader to more in-depth discussions >of the matter in other drafts. Med: Agree. A pointer to http://tools.ietf.org/html/draft-ietf-intarea-nat-reveal-analysis-04#section-3 will be added to the next rev of the draft. The text will also include some discussion for use cases which are restricted to one single administrative domain. Again, here is an area where >being clear about the specific considerations for each use >case is important, identifying whether the other drafts >discuss things so that they are applicable to all of the use >cases, or if the use cases are unique in any number of ways >that will mean that they have unique privacy and security >considerations. > >Thanks, > >Wes George > >> -----Original Message----- >> From: [email protected] [mailto:[email protected]] On >> Behalf Of [email protected] >> Sent: Monday, December 03, 2012 4:08 AM >> To: [email protected]; [email protected] >> Cc: [email protected] >> Subject: [Int-area] draft-boucadair-intarea-host-identifier-scenarios >> >> Dear all, >> >> We submitted an updated version of this draft to list use cases which >> encounter the issue of host identification.
