Body
The purpose of this Liaison is to inform you of a new work proposal
in the Benchmarking Methodology Working Group (BMWG) of the IETF, and seek
your comments and future plans regarding the subject work area.

BMWG has been presented with a new work proposal to benchmark the
Y.1731 OAM capabilities of network devices. Please see
the Internet Draft by Sudhin Jacob and Praveen Ananthasankaran:
https://tools.ietf.org/html/draft-jacpra-bmwg-pmtest-02
In this proposal, there is an intersection between IETF benchmarking
practice and ITU-T standardization and mandates.

The Internet-Draft seeks to characterize the accuracy of performance
monitoring:
* under various traffic conditions,
* during routing engine fail-over (High Availability),
* during multiple OAM test sessions to characterize the scale/capacity, and
* during long test intervals (Soak tests).

This Internet Draft is at an early stage, so considerable review
and development would be necessary, as with all work items.

The charter of BMWG strictly limits our work to laboratory characterization.
Therefore, live network performance testing, manageability, MIB module
development, and other operational/functional testing are beyond our scope.
https://datatracker.ietf.org/wg/bmwg/charter/

We recognize that ITU-T SG 15 is the maintainer of Rec. Y.1731, and that
compliance and interoperability specifications are the mandate of SG 11.
Therefore, prior to considering this work proposal further,
we seek your comments on:
- whether you see this topic as valuable to the Industry
- whether your experience and knowledge of Y.1731 implementations
is essential to complete this work with the necessary quality
- whether there is overlapping work in ITU-T, planned or in-progress
- the proposal details, as currently described, and
- your preference on how to progress this work.

Replies received prior to our March 26, 2017 meeting will be most appreciated.
