—In this paper we investigate traffic-engineering issues in Wavelength Division Multiplexing (WDM) all-optical networks. In such networks, the wavelength continuity constraint along with the wavelength clash constraint, lead to poor network performances when dealing with the lightpath provisioning problem. The impact of these constraints is especially(More)
In transparent optical networks, signals can propagate over long distances without electrical regeneration, causing physical layer impairments to accumulate and make lightpaths' Quality of Transmission (QoT) become potentially unacceptable. Depending on the channel load and transmission distance some paths cannot be set up fully transparently because the(More)
