Technology in the optical domain is constantly evolving, and, as a
consequence, new equipment providing lambda switching capability
has been developed and is currently being deployed.

Generalized MPLS (GMPLS) is a family of protocols that can be
used to operate networks built from a range of technologies
including wavelength (or lambda) switching.  For this purpose,
GMPLS defined a wavelength label as only having significance
between two neighbors.  Global wavelength semantics are not

In order to facilitate interoperability in a network composed of
next generation lambda-switch-capable equipment, this document
defines a standard lambda label format that is compliant with
the Dense Wavelength Division Multiplexing (DWDM) and Coarse Wavelength
Division Multiplexing (CWDM) grids defined by the International
Telecommunication Union Telecommunication Standardization Sector.
The label format defined in this document can be used in GMPLS
signaling and routing protocols.  [STANDARDS-TRACK]
