In this work, the Preventive Assignment of Regenerator (PAR) algorithm is proposed for
regenerator allocation in translucent optical networks. The objective of this proposal is to …

In comparison with wavelength division multiplexing optical networks, elastic optical
networks are much more flexible, presenting an efficient alternative to use the frequency …

In this paper, we propose an evolutionary multiobjective regenerator placement strategy for
elastic optical networks (eMORP). The proposed optimization strategy uses the genetic …

In this paper, we propose two heuristics to perform regenerator assignment in translucent
elastic optical networks. The first one tries to use the modulation format with the highest …

We consider a dynamic lightpath provisioning problem in translucent spectrally–spatially
flexible optical networks (SS-FONs) in which flexible signal regeneration is achieved with …

In this paper, we perform a case study focusing on both regeneration assignment (RA) and
regeneration placement (RP) in a translucent elastic optical network. We consider six …

In this paper we propose a methodology based on an evolutionary multi-objective
optimization algorithm, called NSGA-II to design the topology and define the devices for both …

The problem of regenerator assignment (RA) in translucent optical networks consists in
segmenting a lightpath into several transparent segments, each of which linked by 3 R …

In a dynamically reconfigurable wide-area translucent network, the pre-deployment of
regenerators at few sites has its advantages due to the increased system optimization and …

This work proposes a new regenerator allocation algorithm, named Circuit Invigorating
Regenerators Assignment (CIRA) algorithm. The CIRA selects the regenerators to be …
