Generalized Labels for the Flexi-Grid in Lambda Switch Capable (LSC) Label Switching Routers
A. Farrel, Daniel King, Yunhong LI, Feng Zhang · 2015
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.
