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. However, RFC 3471 has 
defined that a wavelength label (section 3.2.1.1) "only has 
significance between two neighbors" and global wavelength continuity 
is not considered. In order to achieve interoperability in a network 
composed of next generation lambda switch-capable equipment, this 
document defines a standard lambda label format, being compliant with 
ITU-T G.694. Moreover some consideration on how to ensure lambda 
continuity with RSVP-TE is provided. This document is a companion to 
the Generalized Multi-Protocol Label Switching (GMPLS) signaling. It 
defines the label format when Lambda Switching is requested in an all 
optical network.
