When an application source node (N1) applies for subscription to a node to be monitored (N2), the application source node (N1) interconnects with the node to be monitored (N2) and a monitoring node (N3) monitors the node to be monitored (N2). The application source node (N1) determines the life or death of the node to be monitored (N2) by combining a direct response from the node to be monitored (N2) and a notification from the monitoring node (N3). Therefore, it is possible to quickly detect a state change of an object to be managed and distinguish between a failure of the node to be monitored (N2) and a failure of the network. |
