Best, Haoyu From: Adrian Farrel <[email protected]> Sent: Wednesday, December 11, 2019 6:33 AM To: 'Tianran Zhou' <[email protected]>; [email protected]; [email protected] Cc: [email protected] Subject: RE: [OPSAWG] WG adoption call for draft-song-opsawg-ifit-framework-09 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.

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/<https://nam03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdatatracker.ietf.org%2Fdoc%2Fdraft-song-opsawg-ifit-framework%2F&data=02%7C01%7Chaoyu.song%40futurewei.com%7C2e5ca8b5f29c41b9b59e08d77e472fc3%7C0fee8ff2a3b240189c753a1d5591fedc%7C1%7C0%7C637116716543648909&sdata=t42ssFcgSVLkM2V3x6e2Z5qeppa1rcNIvK60S%2FkVAt8%3D&reserved=0> 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
