Joint Minimization of Spectrum and Power in Impairment-Aware Elastic Optical Networks

IEEE Access, 2021
Flexible-grid elastic optical networks (EONs) are widely considered as the future of next generation optical transport networks. Depleting spectral resources and increasing power consumption are two critical bottlenecks of EONs. In this paper, we propose

Optical Grooming in OFDM-Based Elastic Optical Networks [PDF]

Optical Fiber Communication Conference, 2012
We propose a novel optical grooming approach to aggregate and distribute traffic directly at the optical level in OFDM-based elastic optical networks. Significant transmitter and spectrum saving is achieved compared to non-grooming scenario.

Provision of adaptive guard band in elastic optical networks

Journal of Internet Services and Applications, 2020
Elastic optical networks are a network infrastructure capable of withstanding the high demand for data traffic from high-speed networks. One of the problems that must be solved to ensure the smooth functioning of the network is called Routing, Modulation

Channel-Based RSA Approaches for QoS Protection of Slices Over Elastic Optical Networks

IEEE Access, 2022
Resource efficiency and survivability are critical concerns in elastic optical networks (EONs) with virtualization. In this paper, we investigate some important aspects in network survivability design against single-link failure under dedicated ...

Spectrum-Convertible BVWXC Placement in OFDM-Based Elastic Optical Networks

IEEE Photonics Journal, 2017
Spectrum conversion can improve the performance of orthogonal frequency division multiplexing (OFDM)-based elastic optical networks (EONs) by relaxing the continuity constraint and consequently reducing connection request blocking probability during ...

Energy-Efficient Survivable Grooming in Software-Defined Elastic Optical Networks

IEEE Access, 2017
Survivability in the OpenFlow-based software-defined elastic optical networks (SD-EONs) are more challenging than that in the conventional optical networks because failures can affect control plane operations.
