   To enable scaling of existing transport systems to ultra high data
   rates of 1 Tbps and beyond, next generation systems providing super-
   channel switching capability are currently being developed. To allow
   efficient allocation of optical spectral bandwidth for such high bit
   rate systems, International Telecommunication Union
   Telecommunication Standardization Sector (ITU-T) is extending the
   G.694.1 grid standard (termed &quot;Fixed-Grid&quot;) to include flexible grid
   (termed &quot;Flex-Grid&quot;) support. This necessitates definition of new
   label format for the Flex-Grid. This document defines a super-
   channel label as a Super-Channel Identifier and an associated list
   of contiguous or non-contiguous set of 12.5 GHz slices representing
   optical spectrum of the super-channel. The label information can be
   encoded using a fixed length or variable length format. This label
   format can be used in GMPLS signaling and routing protocol to
   establish super-channel based optical label switched paths (LSPs).
