3. Page - 3 77 th IETF – Anaheim, California, March 2010 WSON RWA Framework Scope Control plane models for key wavelength switched optical network subsystems and processes. The subsystems include: –wavelength division multiplexed links, tunable laser transmitters, –reconfigurable optical add/drop multiplexers (ROADM), regenerators and wavelength converters. The RWA process is reviewed and the information requirements are presented, along with alternative implementation architectures. Electro-optical network elements and their compatibility constraints relative to optical signal parameters are characterized Limitations: focuses on topological elements and path selection constraints that are common across different WSON environments and does not address optical impairments.
