PROBLEM TO BE SOLVED: To provide a network topology estimating device which can estimate network topology information more precisely even if a part of management information on each node cannot be received.SOLUTION: The network topology estimating device has present network topology information which indicates present connection relation between nodes constructing a network and past network topology information which indicates past connection relation between the nodes. An estimating section (25), from the present network topology information, selects an estimation target node being a node which has connection relation inconsistent with a predetermined rule, and estimates an actual connection relation of the estimation target node on the basis of the past network topology information. |
