[ippm] Re: [Last-Call] Re: Last Call: Reclassifying "Active and Passive Metrics and Methods (with Hybrid Types In -Between)" (RFC7799)

Hi Ted,

Sure. The rationale was tweaked a bit.

I let IPPM experts further expand if any additional clarification is needed.

Thank you.

Cheers,

Objet : [Last-Call] Re: Last Call: Reclassifying "Active and Passive Metrics and Methods (with Hybrid Types In-Between)" (RFC7799)


Dear IESG,

I am a little confused by the proposal.  The document gives as its purpose:


   The scope of this memo is to define and describe Active and Passive

   versions of metrics and methods that are consistent with the long-

   time usage of these adjectives in the Internet measurement community

   and especially the IETF.  Since the science of measurement is

   expanding, we provide a category for combinations of the traditional

   extremes, treating Active and Passive as a continuum and designating

   combinations of their attributes as Hybrid Methods.



   Further, this memo's purpose includes describing multiple dimensions

   to evaluate new methods as they emerge.
It does an admiral job at that, and I can see in the write-up that this has been reflect in numerous citations in both RFCs and in the work of other SDOs.  What has changed that this needs a new status to do its job?  The supporting document only says this:


RFC 7799<https://datatracker.ietf.org/doc/rfc7799/> is one of the key documents that record IETF current best thoughts

about the classification of various measurement metrics and methods. The

document is normatively cited by other RFCs and cited outside IPPM, including

by other SDOs.



The experience so far supports reclassification of RFC 7799<https://datatracker.ietf.org/doc/rfc7799/> from Informational

to BCP. This is also consistent with the recent approval by the IESG of the

companion document draft-ietf-opsawg-oam-characterization<https://datatracker.ietf.org/doc/draft-ietf-opsawg-oam-characterization/> that will be

published as a BCP. Both documents will be published under the same BCP: BCP 161
The document doesn't really recommend specific practices so much as describe a broad range of them, and it would be helpful to understand why that suddenly needs to be a BCP rather than the well-cited Informational it already is.

I'm sure others closer to the matter understand this, but if you could explain or, better yet, update the reclassification rational with more detail, I think it would help the broader community follow this change.

thanks,

Ted Hardie
