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
status-change-rfc8321-rfc8889-alt-mark-to-ps-00

RFCs 8321 and RFC 8889 describe the "alternate marking method" that uses a few
bits in a protocol header to enable various types of network measurement. These
documents are Experimental, which is complicating the effort to cite them in
Proposed Standards that instantiate these techniques in a particular protocol.

The consensus in the IPPM working groups is that these techniques have been
widely implemented and deployed, and are therefore mature enough to progress to
Proposed Standard. See the thread that starts here:
https://mailarchive.ietf.org/arch/msg/ippm/U-gy4T5XxfxIkdmMK-hWaeRKHwY/

Based on this input, I believe the documents meet the requirements for Proposed
Standard in RFCs 2026 and 6410. They have no known errata.
