Re: [Last-Call] Last Call: RFC 8321 (Alternate-Marking Method for Passive and Hybrid Performance Monitoring) and RFC 8889 (Multipoint Alternate-Marking Method for Passive and Hybrid Performance Monitoring)to Proposed Standard

Thanks for the background information, Giuseppe.

To be clear, none of us who have commented are saying that we don't
think RFCs 8321 and 8889 are ready to move to PS.  We're just saying
that the "status change" mechanism isn't the appropriate way to do it,
and that it should be done with new I-Ds that go into IETF last call
through the normal I-D process.

To avoid downref, the current solution adopted in draft-ietf-6man-ipv6-alt-mark was to take some text from RFC 8321 / RFC 8889 and move into draft-ietf-6man-ipv6-alt-mark so that it can be elevated to PS.

Indeed Alternate Marking is implemented by vendors (e.g. Huawei, Cisco, ZTE, Broadcom..) and deployed by operators (Telecom Italia, China Mobile, China Unicom..) as also confirmed by the answers to the poll launched by Martin Duke two weeks ago on the IPPM mailing list.
