	Title		: Additional Extensions to Generalized MPLS for Waveband

Generalized-MPLS (GMPLS) extends the MPLS control plane to encompass
time-division, wavelength and spatial switching. A functional
description of the extensions to MPLS signaling needed to support
the new types of switching is provided in [GMPLS-SIG]. Along with
the current development of IP over optical switching, there are
considerable developments in optical transport systems based on the
multiple optical switching granularities. [GMPLS-SIG] currently
defines two layers of optical granularity (wavelength and fiber). As
described in [IPO-MG], a revisited definition of waveband switching
must be introduced. This document presents a functional description
of the extensions, to the GMPLS protocol suite, to integrate the
additional requirements of optical multi-granularity and to further
benefit from the features of those switching layers.
