Optical networks and Internet Protocol/Multi-Protocol Label Switching (IP/MPLS) based networks have been traditionally designed and operated by separate departments of network operators. Likewise, both layers have always represented different business areas for system providers, which maintain different product lines for each of them. However, network operators have an IP/ MPLS over WDM architecture. The main drivers for this unique transport network are the cost savings…

A symbolic system synthesis approach for hard real-time systems based on coordinated SMT-solving
We propose an SMT-based system synthesis approach where the logic solver performs static binding and routing while the background theory solver computes global time-triggered schedules. In contrast to previous work, we assign additional time to the logic solver in order to refine the binding and routing such that the background theory solver is more likely…
Perception of noise in global illumination algorithms based on spiking neural network
This paper proposes a reduced reference quality assessment model based on spiking neural network(SNN) in order to predict which image highlights perceptual noise in unbiased global illumination algorithms. These algorithms provide photo-realistic images by increasing the number of paths as proved by Monte Carlo theory. The objective is to find the number of paths that are…
Distributed control plane with spectral fragmentation-aware RMSA and flexible reservation for dynamic multidomain software-defined elastic optical networks
We propose a distributed control scheme utilizing spectral fragmentation-aware RMSA and flexible active/passive reservation mechanism for dynamic multi-domain software-defined elastic opticalnetworks. Our proposed scheme offers significant blocking probability reduction compared to conventional GMPLS/PCE architecture.
Towards 1 Tbit/s SOA-based 1310 nm transmission for local area network/data centre applications
The growing data traffic in the local area networks is driving development of the cost-effective transmission systems that can carry it effectively. In this study, firstly, we investigate the influence of a semiconductor optical amplifier (SOA) on the transmission quality in the 1310 nm wavelength-division-multiplexed system. We examine the differences in the channels gain and…
