Quality of Transmission Awareness in Converged Electronic and Optical Networks with OpenFlow

OpenFlow, as a unified operator-friendly manageable network control approach, has benefits of supporting the convergence of electronic packet and optical circuit networks as well as quality-of-transmission (QoT) awareness. We experimentally present the QoT-awareness in converged OpenFlow networks wi...

Zusammenfassung:	OpenFlow, as a unified operator-friendly manageable network control approach, has benefits of supporting the convergence of electronic packet and optical circuit networks as well as quality-of-transmission (QoT) awareness. We experimentally present the QoT-awareness in converged OpenFlow networks with (i) QoT-aware wavelength reassignment (ii) QoT-aware path re-routing if the QoT is below the requirement. The experimental work validates efficient networking approach and provides a key direction for next generation software defined networks.
