Eavesdropping-Aware Routing and Spectrum Allocation in EONs Using Spread Spectrum Techniques [PDF]
2018 IEEE Global Communications Conference (GLOBECOM), 2018 In this work, eavesdropping-aware routing and spectrum allocation (RSA) techniques are proposed for elastic optical networks (EONs) using orthogonal frequency division multiplexing (OFDM). To introduce physical (optical) layer security and protect these networks against eavesdropping attacks, spread spectrum (SS) with signal overlapping techniques are ...

Towards Optimal and Scalable Solution for Routing and Spectrum Allocation
Electronic Notes in Discrete Mathematics, 2018 Abstract The advent of the flexible spectrum grid (flexgrid) technology for the slicing of the optical spectrum has brought new opportunities in terms of efficient utilization of the spectrum, but also new challenges in terms of scalable algorithms for efficiently provisioning the user requests in a flex optical network, i.e., solving the Routing and
