An introduction to routing and wavelength assignment algorithms for fixed and flexgrid

◂General methods to solve optimization problems in networks ◂WDM networks ◂Goal of planning: satisfy traffic and optimize resource usage ◂Physical layer impairments (cross-layer optimization) ◂Network evolution: establish new connections and re-optimize ◂Flexgrid networks ◂Added complexity due to more flexibility degrees Interdependence among reach-rate-spectrum-guardband parameters Traffic variation can be accommodated at different levels ◂Develop novel formulations ◂Network Planning and Operation Tools - Mantis
