Hi Thomas, Only looking at the abstraction, I think you do not get Greg's comment on on-path telemetry. IMO, this IPFIX extension should only focus on the data export, while independent of specific on-path telemetry protocols. The following draft is a very useful reference for on path telemetry: https://datatracker.ietf.org/doc/draft-song-opsawg-ifit-framework/18/
" On-Path Telemetry (OPT) refers to data-plane telemetry techniques that directly tap and measure network traffic by embedding instructions or metadata into user packets. " " It is essential to recognize that existing work on this topic includes a variety of on-path telemetry techniques, including In-situ OAM (IOAM) [RFC9197], IOAM Direct Export (DEX) [I-D.ietf-ippm-ioam-direct-export], Marking-based Postcard-based Telemetry (PBT-M)[I-D.song-ippm-postcard-based-telemetry], Enhanced Alternate Marking (EAM) [I-D.zhou-ippm-enhanced-alternate-marking], and Hybrid Two-Step (HTS) [I-D.mirsky-ippm-hybrid-two-step], have been developed or proposed. " Hope this is useful for you.
