Dear Mr. Farrel,

Thank you for the Liaison Statement on Comparison of LMP and ASON Discovery. We appreciate the opportunity to provide input to the work. Q14/15 will address the LS in its upcoming meeting next week.

Regards,
Kam Lam, Q14/15 Rapporteur

>    Union (ITU), i.e. G.8080, G.7714, and G.7714.1, and on-going ITU-T
>    work. This document provides an overview of LMP in the context of
>    the ITU-T Automatically Switched Optical Networks (ASON) [G.8080]
>    and transport network [G.805] terminology and relates it to the
>    ITU-T discovery work to promote a common understanding for
>    progressing the work of IETF and ITU-T.
