Extension to the Link Management Protocol (LMP/DWDM -rfc4209) for Dense
Wavelength Division Multiplexing (DWDM) Optical Line Systems to manage
the application code of optical interface parameters in DWDM application
draft-ietf-ccamp-dwdm-if-lmp-01
Abstract
This memo defines extensions to LMP(rfc4209) for managing Optical
parameters associated with Wavelength Division Multiplexing (WDM)
systems in accordance with the Interface Application Identifier
approach defined in ITU-T Recommendation G.694.1.[ITU-T.G694.1] and
its extensions.

1. Introduction
LMP [RFC4902] provides link property correlation capabilities that
can be used between a transceiver device and an Optical Line System
(OLS) device. Link property correlation is a procedure by which,
intrinsic parameters and capabilities are exchanged between two ends
of a link. Link property correlation as defined in RFC3591 allows
either end of the link to supervise the received signal and operate
within a commonly understood parameter window. Here the term 'link'
refers in particular to the attachment link between OXC and OLS (see
Figure 1). The relevant interface parameters are in line with
