Abstract

The recent updated version of ITU-T [G.694.1] has introduced the
flexible-grid DWDM technique, which provides a new tool that operators
can implement to provide a higher degree of network optimization than
is possible with fixed-grid systems.  This document describes the
extensions to the Link Management Protocol (LMP) to negotiate link grid
property between the adjacent DWDM nodes before the link is brought up.
