Dear Giuseppe,

Thanks a lot for the input. That makes perfectly sense that we also describe the applicability onto the SRv6 Segment Routing Header in the Alternate-Marking Method and mention Alternate-Marking Method when the delay is being calculated outside of the network node.

Could you please review the following changes

https://author-tools.ietf.org/diff?doc_1=draft-ietf-opsawg-ipfix-on-path-telemetry-13&url_2=https://raw.githubusercontent.com/network-analytics/draft-ietf-opsawg-ipfix-on-path-telemetry/refs/heads/main/draft-ietf-opsawg-ipfix-on-path-telemetry-14.txt

and let us wherever it addresses your comments. I will submit it then as soon as the submit window is re-opened.

Best wishes
Thomas

Be aware: This is an external email.


Hi All,
I have reviewed the draft and I think it is ready.
Regarding the Alternate-Marking Method, I suggest to add the reference to draft-fz-spring-srv6-alt-mark in section 3.3.2 and section 7.5, since this document also describes the addition of the Timestamp Data Field, similarly to draft-zhou-ippm-enhanced-alternate-marking.
I would also suggest to mention draft-ietf-opsawg-ipfix-alt-mark as another option to use IPFIX to export timestamps and therefore calculate the delay.

Regards,

Giuseppe

This starts a two week WG LC for  draft-ietf-opsawg-ipfix-on-path-telemetry<https://datatracker.ietf.org/doc/draft-ietf-opsawg-ipfix-on-path-telemetry/>.  The authors have been polled and there is no known IPR on this work that has been disclosed at this time.

Please post comments and thoughts on this document's readiness to the list.  If you are interested in being the shepherd for this document, please email opsawg-chairs@.

The WG LC will run until October 24.

Thanks.

Joe
