Regenerator site selection in impairment-aware elastic optical networks [PDF]

, 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 ...
