Zusammenfassung:A node selecting unit (m41) in a management node (N1) selects a backup node for the management node from nodes (N2 to N4) in an overlay network by using the management range to which the node belongs, the volume of data, and an operation time as an index. A data replicating unit (m42) replicates management information to the backup node. If the management node stops, a switching unit (m43) switches the backup node to the management node. Consequently, it is possible to distribute loads of managing network systems and to improve scalability and reliability.
