“…This high and widespread interest in elastic optical networks is due to the ability of EONs to meet the growing demands of bandwidth-intensive applications and services in a flexible and efficient manner. The proposed solution has been essential for the further development of data networks, in view of the exponential growth of data traffic (Big Data) and the emergence of new services [5], [6]. The high scalability of EONs [7], [8] allows them to be used effectively also in solutions with differential quality of service.…”

“…The architecture of an EON network, relying on flexible grid and spectrum allocation, advanced modulation formats, digital signal processing (DSP) techniques, and reconfigurable optical add-drop multiplexers (ROADMs), has been successful in overcoming two major limitations of traditional optical networks: the lack of flexibility in allocating the spectrum and the problem of dynamic bandwidth delivery [3], [4]. The proposed solution was necessary to facilitate further development of information and communication technologies (ICT) networks which are faced with an exponential growth in data volumes and the emergence of new services [2], [5]. The high scalability of EONs [6], [7] allows them also to be used effectively in quality of service differentiating solutions.…”

“…Regarding capital expenditure, up to 19.4% energy savings can be achieved by provisioning ahead coarse-grained designs. Finally, the authors in [202] proposed two new node architectures for optical transport networks beyond 100Gbps, Optical Grooming Capable Optical Cross Connect and Optical Grooming Capable Reconfigurable Optical Add/Drop Multiplexer. The authors focused on optical layer grooming, since it is necessary for beyond 100Gbps containers, in order to take full advantage of the variable grid spacing and to improve spectrum utilization.…”
