Abstract
Provided are a router estimation system and a router estimation method which enable accurate estimation of a router in network slices that is a cause of a silent failure. A policy manager () extracts, when it is determined that a plurality of function elements have deteriorated in performance in slice communication, a plurality of function elements that are similar to one another in terms of shifts in performance in the slice communication from the plurality of function elements determined to have deteriorated in performance. The policy manager () identifies, for each of the plurality of extracted function elements, a group of routers located on a route of the slice communication based on router group data. The policy manager () estimates at least one router included in every router group identified for the each of the plurality of extracted function elements to be a router that is a cause of the deterioration of performance of the plurality of extracted function elements.
