Hi Ruediger,
thank you for the suggested change. I accepted the latter option as:
The access rate metric and method of access rate measurement are out of the scope of this document.
I attached the diff file highlighting all the updates we discussed during the WG LC.

Best regards,
Greg

Hi Greg,

the text of the rate measurement section is chosen very generic and informs the reader, that the functions supported by the draft “...conform to the requirements for measuring access rate..”

https://www.ietf.org/archive/id/draft-ietf-ippm-asymmetrical-pkts-05.html#name-rate-measurement

In addition to other concerns, I note that the draft neither offers a discussion of an access rate metric nor a reference to one. I think, someone performing an access rate measurement by UDP transport needs to have a rough idea, what to do. The introduction of RFC 9097 offers a brief overview on these metrics an defines one itself, see https://www.rfc-editor.org/rfc/rfc9097.html#name-introduction . I’d appreciate, if the draft offers one or more suitable references to an access rate metric or puts that topic out of scope.

In the latter case, suggested text would be:
The access rate metric and method of access rate measurement are out of scope of this document. The UDP Speed Test ([RFC9097<https://www.ietf.org/archive/id/draft-ietf-ippm-asymmetrical-pkts-05.html#RFC9097>] and [I-D.ietf-ippm-capacity-protocol<https://www.ietf.org/archive/id/draft-ietf-ippm-asymmetrical-pkts-05.html#I-D.ietf-ippm-capacity-protocol>] also allows for the measurement of access bandwidth.

That last sentence is part of the draft already, maybe the following reads better, if authors pick up:
The access rate metric and method of access rate measurement are out of scope of this document. The UDP Speed Test ([RFC9097<https://www.ietf.org/archive/id/draft-ietf-ippm-asymmetrical-pkts-05.html#RFC9097>] and [I-D.ietf-ippm-capacity-protocol<https://www.ietf.org/archive/id/draft-ietf-ippm-asymmetrical-pkts-05.html#I-D.ietf-ippm-capacity-protocol>] offers both.

Regards,

Ruediger

Subject: [ippm] Working group last call for draft-ietf-ippm-asymmetrical-pkts

Hello IPPM,

This email initiates the working group last call for Performance Measurement with Asymmetrical Traffic Using STAMP (draft-ietf-ippm-asymmetrical-pkts).

The current version of the document can be found here:
https://datatracker.ietf.org/doc/draft-ietf-ippm-asymmetrical-pkts/
https://www.ietf.org/archive/id/draft-ietf-ippm-asymmetrical-pkts-05.html

Please review the document and reply to this email with any comments and indicate whether you believe it is ready for publication. This WGLC will last for three weeks and end on May 1, 2025.

BR,
Marcus and Thomas
