A Framework for the Control of Wavelength Switched Optical Networks (WSON) with Impairments
The operation of optical networks requires information on the physical characterization of optical network elements, subsystems, devices, and cabling. These physical characteristics may be important to consider when using a GMPLS control plane to support path setup and maintenance. This document discusses how the definition and characterization of optical fiber, devices, subsystems, and network elements contained in various ITU-T recommendations can be combined with GMPLS control plane protocols and mechanisms to support Impairment Aware Routing and Wavelength Assignment (IA-RWA) in optical networks.
