Purpose: In response

Referenced liaison: LS on harmonization of IP Capacity and Latency Parameters: Consent of Draft Rec. Y.1540 on IP packet transfer performance parameters and New Annex A with Lab & Field Evaluation Plans (https://datatracker.ietf.org/liaison/1645/)

Body: The IPPM Working Group in IETF thanks ITU-T SG12 for their liaison describing progress on the Maximum IP-layer Capacity metric and methods in revised Rec. Y.1540. The development of a coordinated specification has proceeded successfully in IETF, with the benefit of the review by new experts contributing at the working group and IESG level. The many lab and field test results you shared have been a great asset, so we made references to your results, as well as the testing conducted during Hackathons at recent IETF meetings.
The latest draft is available [0], which we expect to be approved shortly.
The next step appears to be development/enhancement of a test protocol to support the measurement method with its feeback measurements and dynamic sender rate control.
The IPPM Working Group continues to seek participation by all interested parties, and will keep you informed of our progress on the topic of the Maximum IP-layer Capacity metric and methods.
