摘要： There is provided topology information including connection states among nodes in a network, and port information including restriction conditions on connectivity among ports within a restricted node. A path search apparatus finds a first path having the minimum total link-cost among a plurality of paths. The topology information is changed so that the first path is not searched for as a path having the minimum total link-cost among the plurality of paths, and the port information is changed based on a port connectivity change rule. Then, the path search apparatus finds a second path different from the first path, based on the changed port information and the changed topology information, and reconfigures a pair of link-disjoint paths satisfying the restriction conditions imposed on the restricted node, by removing a link shared by both the first and second paths from the original topology information.

摘要： According an aspect of the embodiment, there is provided a method for accommodating signal paths to a ring network. A demand chain is defined as a series of traffic demands in which each traffic demand shares one of the pair of terminal nodes pointed thereby with at least one adjacent traffic demand and the number of pairs of terminal nodes pointed by traffic demands in the series of traffic demands is maximized. Each traffic demand of the demand chain is corresponded to a demand accommodating route which is defined as a route between the pair of terminal nodes on the ring network pointed by the each traffic demand and arranged in a predetermined rotation direction on the ring network. Then, signal paths required by traffic demands each pointing a pair of terminal nodes both included in the demand accommodating route chain are accommodated to the demand accommodating route chain.

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.
