Abstract
Provided are a router estimation system and a router estimation method which enable accurate estimation of a router that is a cause of silent failures in network slices. A policy manager () identifies, for each one of a plurality of slice communications held in a communication system, the number of pairs that include the slice communication and that are each linked to a degree of correlation decrease satisfying a decrease determination condition. The policy manager () estimates at least one router as a router that is a cause of deterioration of performance of function elements related to the slice communication, the at least one router being included in a group of routers which are identified based on router group data and which are located on a route of the slice communication for which the number of the pairs that satisfies a given pair count condition is identified.
