PROBLEM TO BE SOLVED: To enable accurate notification of the occurrence of a fault.SOLUTION: A determination device includes: an LSA acquisition unit which acquires a plurality of LSA transmitted from a plurality of nodes in a network conforming to OSPF; a logical channel determination unit which, based on the plurality of LSA, determines whether or not each logical channel of the plurality of nodes fails; a physical channel identification unit which identifies a physical channel corresponding to a logical channel, on the basis of node setting information on which a logical channel is determined to be in failure; and a trouble part determination unit which determines a physical trouble part in the network, on the basis of physical configuration information, which indicates the configuration of physical connection of the plurality of nodes and transmission devices between each node, and the physical channel identified by the physical channel identification unit.SELECTED DRAWING: Figure 2 |
