摘要： In a network, a controller controls a physical-interconnection selection switch and middle switches so as to dynamically change a network topology according to the state of the network. A traffic analyzer detects how the traffic in the network changes. If there is a change in traffic, the controller controls the physical-interconnection selection switch and the middle switches so as to change the network topology to one suitable for the changed traffic.

摘要： The objective of the present invention is to realize a chromatic dispersion compensation method which does not depend on a wavelength path in a photonic network to which a HUB node is applied and its monitoring control. In order to achieve this purpose, the present invention controls a plurality of variable chromatic dispersion compensators arbitrarily disposed in the photonic network based on the measured results of a plurality of chromatic dispersion monitors arbitrarily disposed in the photonic network and wavelength path information kept by the network management system which manages the entire photonic network. Here, the variable chromatic dispersion compensator within the network that should be controlled and the chromatic dispersion compensated quantity thereof are determined based on the measured results of the chromatic dispersion monitor and the wavelength path information kept by NMS.
