We submited a new draft and posted it in the IETF datatracker
https://datatracker.ietf.org/doc/draft-song-opsawg-ipfix-ecn/
The following IPFIX information elements are introduced for L4S ECN monitoring:
- ECN field capture in protocol layer, including ECN field in IPv4/IPv6 ECN
field, MPLS EXP and tunnel ECN negotiation status
- ECN codepoint statistics, including incremenatl and total count for non-ECT,
ECT(0), ECT(1) and CE packets
- L4S performance indicator, providing short-term and long-term view of
congestion experienced by L4S traffic
Your review, comments and questions are welcome.
