Abstract

As described in [RFC3945], GMPLS extends MPLS from supporting only Packet Switch Capable (PSC) interfaces and switching, to also support four new classes of interfaces and switching that include Lambda Switch Capable (LSC).

                 Generalized Labels for the Flexi-Grid in           Lambda Switch Capable (LSC) Label Switching Routers

Abstract

   GMPLS supports the description of optical switching by identifying    entries in fixed lists of switchable wavelengths (called grids)    through the encoding of lambda labels.  Work within the ITU-T Study    Group 15 has defined a finer-granularity grid, and the facility to    flexibly select different widths of spectrum from the grid.  This    document defines a new GMPLS lambda label format to support this    flexi-grid.

   This document updates RFCs 3471 and 6205 by introducing a new label    format.
