Modern optical networks depend upon advanced software-defined networking (SDN)
technologies, which in turn rely on a network abstraction to infer the quality of transmission …

Traffic grooming (TG) has been proposed in two ways as electrical and optical grooming to
efficiently utilize spectrum and transponders due to omitting guard bands between adjacent …

Lightpaths within optical line systems (OLS) s that deploy coherent optical technologies are
mainly impaired by two additive Gaussian disturbances: the amplified spontaneous …

In this paper, we study the quality of transmission (QoT) aware routing, modulation level, and
resource assignment problem for transparent flexible optical networks over few-mode multi …

This article studies the cross-layer network planning that tries to combine flexible Ethernet
