Claim Text:
1. A network apparatus used in an optical network, the network apparatus comprising: one or more first tunable and temperature controlled (TTC) lasers; one or more transmitters each of which is connected to one of said one or more TTC lasers; one or more second TTC lasers; one or more digital signal processing (DSP) transponders (TPNDs) each of which is connected to one of said one or more second TTC lasers; one or more receivers; a flexible-grid wavelength selective switch (WSS); a controller to: a flow map graphical user interface to view, query, and modify in software physical downstream (DS) and upstream (US) connections; wherein said one or more transmitters defragment an optical access spectrum, and said one or more DSP TPNDs exploit a newly available spectrum, and wherein the physical DS and US connections are virtualized as logical flows between bidirectional OpenFlow port identifiers.
