Network management apparatus, method, and program

Abstract

A network management device includes a priority calculation unit to apply, to a situation in which, when a failure in communication occurs in a plurality of buildings that houses a communication facility. When a condition in which the failure that occurred is assumed to be restored regarding a plurality of combinations of some buildings among the buildings in which the failure has occurred by performing restoration on the communication facility housed in the building is applied, the failure in communication continuously occurs in a building that houses a communication facility used for providing a predetermined type of communication service among the plurality of buildings, a policy that defines weighting corresponding to the situation and calculate, for each of the plurality of combinations, priority of a possible combination of buildings in which the failure that occurred is to be actually restored among the buildings in which the failure has occurred.
