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 ...
Regenerator site selection in impairment-aware elastic optical networks

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

We propose a novel regenerator site selection scheme for nonlinear impairment-aware elastic optical networks. The proposed scheme reduces bandwidth use by up to 40% in a realistic network by employing only 6 regenerator sites.
