[Int-area] ACTION REQUIRED: Extending working group last call for draft-ietf-intarea-nat-reveal-analysis-02
Hi all, The WGLC on this draft ended with no comments at all. In this context, we cannot assume that silence equates to consent. In order for this draft to progress, we need people to read the draft and provide their opinions on whether the draft is ready. To enable people to comment, the last call period is extended until Friday July 6, 2012.

I support draft-ietf-intarea-nat-reveal-analysis going forward. I would like the draft to include a citation of MAP (draft-ietf-softwire-map), and mention MAP in its abstract. This is because many technologists assume address sharing only occurs with NAT, even though it occurs with a bunch of other technologies. On this point, I noticed "application proxies" is mentioned in the abstract (which is good), but application proxies are not mentioned again in the introduction to draft-ietf-intarea-nat-reveal-analysis nor mentioned in RFC6269 ("Issues with IP Address Sharing"). -d > -Original Message- > From: int-area-boun...@ietf.org [mailto:int-area-boun...@ietf.org] On > Behalf Of Suresh Krishnan > Sent: Wednesday, June 27, 2012 8:57 AM > To: Internet Area > Subject: [Int-area] ACTION REQUIRED: Extending working group last call > for draft-ietf-intarea-nat-reveal-analysis-02 > > Hi all, > The WGLC on this draft ended with no comments at all.

Re: [Int-area] ACTION REQUIRED: Extending working group last call for draft-ietf-intarea-nat-reveal-analysis-02
With the changes to this draft in the -02 version, I'm having a little trouble seeing its purpose. It basically now seems like a shell for the recommendation in 3.3, with the analysis stuffed into appendices. But given that there is no stable proposal for the actual TCP option to be implemented, what is the purpose for advancing this document right now? I think I've heard that folks "needed to know what to implement," but does this document really resolve that problem given that even within the space of TCP-option-based solutions for this, there are multiple different proposals, none of which has been standardized? This document made more sense when it was just a comparison of the different potential solutions spaces. Some other comments: Section 2 claims that for all solutions analyzed, the draft explains what the HOST_ID is. I don't think this is true for the TCP option solution for the application header solution. Even the specific solution proposals for both of those (draft-wing-nat-reveal-option or draft-ietf-appsawg-http-forwarded) are not specific about the limits to which IDs can be inserted. Section 3.1: Is this really specifying requirements for all solutions? Is that sort of a self-fulfilling prophecy for a document that already has a solution chosen? Given that the Forwarded header is being standardized, it seems like references to XFF should be reduced to places where existing deployments are being discussed (as opposed to encouraging the use of XFF, e.g., in A.8.1, "service providers...can enable the feature of injecting the XFF header"). As a general matter I think it would be helpful for this document to be reviewed by some appsarea folks and/or the authors of draft-ietf-appsawg-http-forwarded. It seems like A.8.1 and A.8.2 contradict each other about whether header information is preserved through multiple address sharing functions. Also, if XFF is in such widespread use, the question of what to do when the TCP option and the XFF header conflict seems like something that needs to be resolved. It seems odd to reference "earlier versions" of draft-wing-nat-reveal-option in A.5.2 rather than just explaining why this option is limited to SYN. This seems like an artifact of the oddness of having a whole document just to recommend an as-yet-unspecified solution.

BTW, the MAP doc cites RFC 6145, which has errors as follows: 1. it sets IPv4 ID=0 when IPv6 lacks a frag header that will hopefully be possible after ipv4-id-update is final, but wasn't valid a the time the doc was published 2. copying the low 16 bits of the IPv6 ID field to the IPv4 ID field is invalid that field might not follow the ID uniqueness criteria of IPv4 3. the system assumes IPv4 can reassemble 1280 byte packets but only 576 can be assumed I've brought these to the attention of the authors...

As a co-author, I didn't want to remain silent per se, so I'll at least be public in my view. I think the doc is good, but I do take Alissa's concerns to point - it might be preferable to remove section 3.3 and leave this doc as a comparison of solutions, and avoid any recommendation of a way forward at this point.

But 3.3 and other text go beyond a comparison. I also don't understand why INTAREA is entertaining work that is clearly intending to define new TCP options. None of the -abdo- drafts have been presented in TCPM or even discussed on the mailing list. (My guess is that the authors know that this would never get traction in TCPM and are venue shopping.)

Dear Joe, all, Apologies for the delay to answer (I was out of office). I have no problem to remove Section 3.3 if this is what the WG wants. As a reminder, I added that section after the Paris meeting in accordance with what I heard in the meeting: more voices in favour of adding a recommendation. I sent a notification to the mailing list mid-april to acknowledge this change. Now, I'm waiting for a feedback from the WG to maintain or to remove Section 3.3.
