Online QoS guarantee scheme in wavelength-routed optical networks

The rapid progress on optical performance monitoring technology makes it possible for optical network designers to guarantee the QoS quality of lightpaths in Wavelength Division Multiplexing (WDM) network. This article describes the basic idea of online QoS guarantee scheme, focusing on the distributed optical noise figure calculation algorithm and optimal design heuristic.
