Abstract:
To allow efficient allocation of optical spectral bandwidth for high
bit-rate systems, the International Telecommunication Union
Telecommunication Standardization Sector (ITU-T) has extended its
Recommendations G.694.1 and G.872 to include a new dense wavelength
division multiplexing (DWDM) grid by defining a set of nominal
central frequencies, channel spacings and the concept of "frequency
slot". In such an environment, a data plane connection is switched
based on allocated, variable-sized frequency ranges within the
optical spectrum creating what is known as a flexible grid (flexi-
grid).
Given the specific characteristics of flexi-grid optical networks and
their associated technology, this document defines a framework and
the associated control plane requirements for the application of the
existing GMPLS architecture and control plane protocols to the
control of flexi-grid DWDM networks. The actual extensions to the
GMPLS protocols will be defined in companion documents.
