Abstract
An abnormality locating apparatus locates an abnormal location in a network. An abnormal location judging part judges a normality or abnormality of a link based on a normality or abnormality of an observation flow, by acquiring information of links through which each observation flow passes, from a network route information storage that stores passing route information of observation flows passing through the links. A diagnosis accuracy judging part judges that an accuracy of judging the normality or abnormality of a connecting link connected to a first node deteriorates, by acquiring links connected to each relay node as connecting links from a relay node connecting link information storage that stores connecting link information of each relay node, and judging that a relay node having all connecting links thereof that are abnormal is the first node having all observation flows passing therethrough that are abnormal.
