Hi Martin, In RFC 8321 there are only two alternatives in relation to the number of bits: single marking and double marking. And both are implemented. As author of RFC 8321, I think that it can be simply elevated as is to PS by slightly revising or by omitting some text that refers to the experiment already done (e.g. section 5).

In a perfect world I would ask the WG to do a bis draft to inventory what is mature and to deprecate the bits that haven't seen real deployment. If it turns out that it's all deployed, then we could do a simpler document action. Is this work that anyone is interested in taking on?

I think I read that some parts were not implemented and I look to those who reported on their implementations to say what they did. This thinning-out of non-implemented capabilities was a feature of Standards Track Advancement processes in the past, so it makes sense to apply it here as well. I realize this means a new draft, but the processing could be accelerated to match the need. If the entire RFC 8321 was implemented, then this point is a non-issue. hope this helps, Al From: ippm <ippm-bounces@ietf.org<mailto:ippm-bounces@ietf.org>> On Behalf Of Martin Duke Sent: Friday, August 20, 2021 12:31 PM To: Ran Pang(联通集团中国联通研究院-本部) <pangran@chinaunicom.cn<mailto:pangran@chinaunicom.cn>> Cc: IETF IPPM WG <ippm@ietf.org<mailto:ippm@ietf.org>> Subject: Re: [ippm] RFC 8321 and 8889 Thanks all, I'm hearing strong consensus that 8321 should be a PS and somewhat weaker support for 8889, but no dissents.

IIUC, this is very much how things are "supposed to work" -- measurement definitions and methodology are done by IPPM, and the protocol-specific instantiations are in the respective working groups. However, there are complications in that 8321 and 8889 are Experimental RFCs, and the ipv6-alt-mark draft is a Proposed Standard. This has resulted in text from 8321/8889 going into ipv6-alt-mark so that it can be elevated to PS. I'm told that, if the status quo holds, other drafts will reference ipv6-alt-mark to avoid a downref. This seems suboptimal. I would prefer that we take one of the two following actions: 1) If the WG has consensus that we are comfortable that there is enough experience with 8321 and/or 8889 to elevate them to PS, I can initiate a document action to change their status. 2) If there is no such consensus, ipv6-alt-mark should be Experimental. In either case, the draft can probably lose some of the duplicate text. Logically, there is a third option -- that the bits of the RFCs copied in the draft are mature enough to be a standard, but that the others aren't. Though I'm not an expert, I doubt this is the case. But if people believe it to be true, we'll have to come up with new options. I would be grateful for the working group's thoughts about these documents and the ideas therein. Is it reasonable for people to read and reflect on this by 26 August (2 weeks from today?)
