Abstract 

   This memo describes the extensions to RSVP-TE signaling to support 
   Label Switched Paths in a GMPLS-controlled network that includes 
   devices using the flexible optical grid.

1. Introduction 

   [G.694.1] defines the Dense Wavelength Division Multiplexing (DWDM) 
   frequency grids for Wavelength Division Multiplexing (WDM) 
   applications. A frequency grid is a reference set of frequencies 
   used to denote allowed nominal central frequencies that may be used
