Connection provisioning in QoT-guaranteed distributed all-optical networks
— As an optical signal propagates along a lightpath to its destination in wavelength-routed optical networks (WRONs), the quality of transmission (QoT) is degraded by transmissio...

Multipoint-to-point lightpaths in all-optical networks: Dimensioning and cost analysis
One of the major concerns in optical networks is the bandwidth underutilization problem. In fact, as WDM technology keeps maturing, there is a bandwidth gap between the transmissi...
