An impairment-aware resource allocation scheme for dynamic elastic optical networks

Dharmaweera, M.N.; Yan, L.; Zhao, J.; Wymeersch, H.; Agrell, E. (2017)

By using impairment-driven variable guardbands, our proposed dynamic resource allocation scheme accommodates 50% more traffic in comparison to existing fixed transmission-reach- and guardband-based algorithms.
Nonlinear-Impairments- and Crosstalk-Aware Resource Allocation Schemes for Multicore-Fiber-based Flexgrid Networks

Dharmaweera, M.N.; Yan, L.; Zhao, J.; Wymeersch, H.; Agrell, E. (2016)

Abstract: In this study, we propose a novel spectrum and core allocation scheme that incorporates both intra-core physical layer impairments and inter-core crosstalk. We demonstrate that accounting for the latter increases ...
Novel impairment-aware resource allocation scheme for elastic optical networks serving traffic with different service priorities

Munasinghe, K.; Dharmaweera, M.N.; de Alwis, C. (2019)

In this research paper, we propose a novel impairment-aware resource allocation scheme that increases spectrum efficiency of an elastic optical network (EON), while satisfying the quality of transmission (QoT) requirements ...
