RSVP-TE Signaling Extensions in Support of Flexi-Grid
Dense Wavelength Division Multiplexing (DWDM) Networks
Abstract
This memo describes the extensions to the Resource Reservation
Protocol - Traffic Engineering (RSVP-TE) signaling protocol to
support Label Switched Paths (LSPs) 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
for defining applications that utilize WDM transmission. The channel
spacing is the frequency spacing between two allowed nominal central
frequencies. All of the wavelengths on a fiber use different central
