Attack-aware Lightpath Provisioning in Elastic Optical Networks with Traffic Demand Variations
Manousakis, Konstantinos; Panayiotou, Tania; Kolios, Panayiotis; Tomkos, Ioannis; Ellinas, Georgios (2019)This work considers lightpath provisioning in elastic optical networks with traffic demand variations while accounting for the impact of jamming attacks. Traffic requests are modeled based on their variation in traffic and ...

A Data-Driven Bandwidth Allocation Framework With QoS Considerations for EONs
Panayiotou, Tania; Manousakis, Konstantinos; Chatzis, Sotirios P.; Ellinas, Georgios (2019)This paper proposes a data-driven bandwidth allocation (BA) framework for periodically and dynamically reconfiguring an elastic optical network according to predictive BA (PBA) models. The proposed framework is scalable ...

Eavesdropping-Aware Routing and Spectrum/Code Allocation in OFDM-Based EONs Using Spread Spectrum Techniques
Savva, Giannis; Manousakis, Konstantinos; Ellinas, Georgios (2018)In this work, eavesdropping-aware routing and spectrum/code allocation techniques are proposed for elastic optical networks (EONs) using orthogonal frequency division multiplexing (OFDM). To introduce physical (optical) ...

Network Coding for Security Against Eavesdropping Attacks in Elastic Optical Networks
Savva, Giannis; Manousakis, Konstantinos; Ellinas, Georgios (Springer International Publishing, 2020)In this work, routing and spectrum allocation (RSA) algorithms together with network coding (NC) are proposed for elastic optical networks. NC has been used in optical networks for protection against link failures and also ...

On learning bandwidth allocation models for time-varying traffic in flexible optical networks
Panayiotou, Tania; Manousakis, Konstantinos; Chatzis, Sotirios P.; Ellinas, Georgios (2018)We examine the problem of bandwidth allocation (BA) on flexible optical networks in the presence of traffic demand uncertainty. We assume that the daily traffic demand is given in the form of distributions describing the ...

Spread Spectrum over OFDM for Enhanced Security in Elastic Optical Networks
Savva, Giannis; Manousakis, Konstantinos; Ellinas, Georgios (2018)In this work, spread spectrum with signal overlapping techniques are used to secure confidential connections against eavesdropping. Routing and spectrum allocation algorithms are proposed in order to establish a set of ...

Survivable and Secure Elastic Optical Networks using Network Coding
Savva, Giannis; Manousakis, Konstantinos; Ellinas, Georgios (2019)In this work, the concept of network coding (NC) is used in conjunction with the routing and spectrum allocation (RSA) problem to jointly provide security and protection in elastic optical networks (EONs). Specifically, ...
