Title : Generalized Labels for Lambda-Switching Capable Label Switching Routers
Author(s) : T. Otani, et al.
Filename : draft-ietf-ccamp-gmpls-g-694-lambda-labels-05.txt

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, [RFC3471]
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 either [G.694.1](DWDM-grid) or [G.694.2](CWDM-grid). 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.
