Abstract

A failure location estimation apparatus sets partial networks obtained by dividing a network into one or more networks, and verifies connectivity of a path for each of combinations of terminal nodes for each of the partial networks. The failure location estimation apparatus selects some or all combinations of the combinations of terminal nodes determined to have an abnormality in connectivity for each of the partial networks, and verifies connectivity of a path for each of combinations of nodes included in a selected node connection that is the selected combinations of terminal nodes. The failure location estimation apparatus estimates a failure location in the network based on a verification result of connectivity of each of the combinations of nodes.
