Routing and Spectrum Assignment Based on Reinforcement Learning in Multi-Band Optical Networks
Prague Stringology Conference, 2023 A routing and spectrum assignment strategy based on Reinforcement Learning (RL-RSA) is proposed for multi-band optical networks. RL-RSA accounts for Stimulated Raman Scattering using the Generalized Gaussian Noise model.

Tree-determination, routing, and spectrum assignment using point-to-multipoint coherent optics
Journal of Optical Communications and Networking, 2023 In this paper, we investigate a novel problem for dimensioning optical networks with digital subcarrier-based point-to-multipoint (P2MP) coherent transceivers, which we refer to as tree-determination, routing, and spectrum assignment (TRSA).

Journal of Microwaves, Optoelectronics and Electromagnetic ApplicationsElastic optical networks (EONs) have characteristics that meet the growing demand for current and future bandwidth, such as 5G and Internet of Things. In EONs, connections must have a route and a spectrum slice available between the nodes to establish ...

Crosstalk-Aware Routing Spectrum Assignment And Wss Placement In Flexible Grid Optical Networks [PDF]
Journal of Lightwave Technology, 2017 Due to crosstalk-induced interactions among different connections, malicious high-power jamming signals can potentially spread widely in a transparent optical network. Moreover, due to imperfect port isolation in wavelength selective switches (WSSs), present within optical switching nodes, crosstalk also affects the quality of the transmitted signal ...
