Title: Re: Comparison of LMP and ASON Discovery


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

> The abstract of this draft is as follows:
>    The Link Management Protocol (LMP) has been developed as part of
>    the Generalized MPLS (GMPLS) protocol suite to manage Traffic
>    Engineering (TE) links. The GMPLS control plane (routing and
>    signaling) uses TE links for establishing Label Switched Paths
>    (LSPs). This memo describes the relationship of the LMP procedures
>    to 'discovery' as defined in the International Telecommunication
>    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.
