Abstract:
This document defines a framework and the associated control plane
requirements for the GMPLS based control of flexi-grid DWDM networks.
To allow efficient allocation of optical spectral bandwidth for high
bit-rate systems, the International Telecommunication Union
Telecommunication Standardization Sector (ITU-T) has extended the
recommendations [G.694.1] and [G.872] to include the concept of
flexible grid. A new DWDM grid has been developed within the ITU-T
Study Group 15 by defining a set of nominal central frequencies,
channel spacings and the concept of "frequency slot". In such
environment, a data plane connection is switched based on allocated,
variable-sized frequency ranges within the optical spectrum.
