Generalized Label for Super-Channel Assignment on Flexible Grid
2013
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 "Fixed-Grid") to include flexible grid (termed "Flex-Grid")
support (draft revised ITU-T G.694.1, revision 1.4, Oct 2011). 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 12.5 GHz slices representing the 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).
