Body
Thank you for your liaison titled “Proposal to Develop a Benchmarking
Methodology for ITU-T Recommendation Y.1731 OAM Performance”.

Q10/15 took note of your charter strictly limiting your work to laboratory
characterization.

We appreciate that IETF BMWG requested our comments prior to considering this
work proposal further. Regarding your recognizing that “compliance and
interoperability specifications are the mandate of SG 11”, we would like to
clarify that while ITU-T SG11 leads ITU’s work on conformance and
interoperability (C&I) testing and is responsible for coordinating ITU’s C&I
programme, ITU-T SG11 and SG15 currently have no agreement regarding where in
ITU-T the work you are interested in with respect to Recommendation ITU-T
G.8013/Y.1731 would take place. Further, we would like to clarify, by reference
to the question text for Q10/15
(https://www.itu.int/en/ITU-T/studygroups/2017-2020/15/Pages/q10.aspx), that
Q10/15 is currently not chartered to work on tasks such as the laboratory
characterization of the accuracy of performance monitoring sought by the
Internet Draft at https://tools.ietf.org/html/draft-jacpra-bmwg-pmtest-02.
However, Q10/15 believes that such tasks should be performed within the
organization that has responsibility for the corresponding data plane
protocols. As such, Q10/15 believes that the proposed work should not be
further progressed in IETF.

The next meeting of ITU-T SG15 is in Geneva, Switzerland, 19-30 June 2017.
