On the generic use case, I see RFC 8403 in this working group, which is based on MPLS data plane.

Subject: [spring] Request for adoption https://datatracker.ietf.org/doc/html/draft-song-spring-siam-01 “SRv6 In-situ Active Measurement”

SPRING WG,
As the draft “draft-ietf-spring-stamp-srpm-01” has been adopted, I also ask the WG to consider the following related draft:

https://datatracker.ietf.org/doc/html/draft-song-spring-siam-01 “SRv6 In-situ Active Measurement”

We have presented this draft in the last meeting but we didn’t have much time to discuss it yet.
In essence, it proposes to carry IOAM in SR+UDP as well while using a flag bit in SRH to indicate the presence of the IOAM payload.
It achieves IOAM’s functionality but avoids the encapsulation issues. It doesn’t need to maintain sessions and it can monitor all the segment noes on an SR path.
I would also like to ask for feedbacks from the WG and request the adoption.  Thanks for consideration.

Best regards,
Haoyu
