Abstract:
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).
