Integrated VONE Scheme Over Resource-Virtualized Elastic Optical Networks
IEEE Access, 2019 To eliminate the ossification of optical infrastructure and adapt to the high-performance Internet applications, optical network virtualization is an important enabler to offer each application type a dedicated virtual optical network (VON).

Migration Planning from Elastic Optical Networks to Spectrally-Spatially Flexible Optical Networks [PDF]
2018 Photonics in Switching and Computing (PSC), 2018 We focus on a migration planning from elastic to spectrally-spatially flexible optical networks by upgrading regular with SDM-capable ROADMs. Our most promising strategy reveals that by migrating 30% of the regular ROADMs a 2x carried traffic increase can be achieved.

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.

Phase chirality and stereo-selective swelling of cholesteric elastomers [PDF]
, 2003 Cholesteric elastomers possess a macroscopic ``phase chirality'' as the director n rotates in a helical fashion along an optical axis $z$ and can be described by a chiral order parameter.

Analytical Model of a Single Link of Elastic Optical Networks
IEEE Access, 2022 This article discusses and evaluates a model of resources to which multiservice traffic is offered. The initial assumption for the model is that calls of particular traffic classes are always serviced in neighboring allocation units of the resources ...

Imprecise Markov Models for Scalable and Robust Performance Evaluation of Flexi-Grid Spectrum Allocation Policies [PDF]
, 2018 The possibility of flexibly assigning spectrum resources with channels of different sizes greatly improves the spectral efficiency of optical networks, but can also lead to unwanted spectrum fragmentation.We study this problem in a scenario where traffic

Brownian motion in a Maxwell fluid. [PDF]
, 2011 The equilibrium dynamics of a spherical particle immersed in a complex Maxwell fluid is analyzed in terms of velocity autocorrelation function (VACF), mean-square displacement (MSD), and power spectral density (PSD). We elucidate the role of hydrodynamic
