Re: [OPSAWG] WG adoption call for draft-song-opsawg-ifit-framework-09

["Adrian Farrel" <[e-mail]>]

Hi,

 

I sent the authors comments on a previous version of the document and

the authors made updates to address my concerns.

 

Considering this adoption poll, I have done another review of the draft.

I think it provides a useful overview of in-situ telemetry approaches and

Will serve the WG well. I'm glad that the authors have included section

3.2 because draft-ietf-opsawg-ntf is also important work and we need to

progress the two documents in close relationship. I am also glad there 

are good and clear references to the iOAM work.

 

I support adoption of the draft and commit to review it during WG

progress. I also have a few comments below: I don't think they need to

be addressed before adoption so long as they are picked up some time.

 

Thanks,

Adrian

The Abstract is about 10 lines too long. We should be aiming at no more

than 25 lines. 

 

I would remove the first sentence. It is out of place and begs the

question of what "telemetry" means.

The style guide says that the "Requirements Language" should be placed

in the body of the document. I suggest you create Section 2.1 for it.

A couple of things with Section 4.4 worry me. Proposing new extension

headers for IPv4 is unlikely to go down well in the IETF where new work

on IPv4 is now frowned upon, and where IPv4 extension headers are 

considered somewhat fragile. Additionally, I think you need to be very

careful with proposals around the Router Alert, and you shouldn't 

mention it or RFC 2113 without also mentioning RFC 6398. Lastly, I think

that you may be giving too much attention to individual drafts that 

possibly do not yet have a body of support in the IETF: in particular,

referencing draft-herbert-ipv4-eh may be premature.

I think we will need to give more attention to discussing security in

section 8. It is true that the details of the security for different

mechanisms are contained in the individual referenced documents. Our

focus in this document should be considering the overall security of

IFIT approaches. This should serve as a guide to the developers of the

various referenced documents, and it should provide observations on how

(or even if) to use IFIT systems.

Hi WG,

 

On IETF 106 meeting, we saw predominant interest and support to this draft,
especially from operators. The authors then resolved all the open issues.

As requested by the authors, this email starts a 2 weeks working group
adoption call for draft-song-opsawg-ifit-framework-09.

https://datatracker.ietf.org/doc/draft-song-opsawg-ifit-framework/ 

 

If you support adopting this document please say so, and please give an
indication of why you think it is important. Also please say if you will be
willing to review and help the draft.

If you do not support adopting this document as a starting point to work on,
please say why.

This poll will run until Dec 23..

 

Thanks,

Tianran as co-chair
