Abstract
A network controller included in an optical transmission system in which an optical transmitter and an optical receiver communicate with each other via an optical transmission path, the network controller including a simulator that constructs simulation models by virtually reproducing a state of an optical transmission path in an optical transmission system including the optical transmitter, the optical receiver, and the optical transmission path in different virtual spaces, and estimates a characteristic of a device provided in the optical transmission path in each of simulation models, and an ideal output estimator that estimates an output of a characteristic of an ideal device based on a characteristic of the device estimated by the simulator and a characteristic of a device provided in the optical transmission path obtained in a real space, in which a state of an optical transmission path is different for each of the simulation models.
