1. A management system comprising:

  • a plurality of nodes, a node from among the plurality of nodes operating as an application source node, a node to be monitored or a monitoring node, wherein;

    the application source node applies for subscription of alive and dead state information to the node to be monitored;

    the node to be monitored, upon receiving the applied subscription, makes a connection with the application source node and makes a request to the monitoring node whose routing table includes the node to be monitored for monitoring the node to be monitored and notifying the application source node of a monitoring result;

    the monitoring node monitors the node to be monitored upon receiving the request from the node to be monitored and makes a down notification to the application source node upon not receiving a response from the node to be monitored, the down notification notifying that the node to be monitored is down; and

    the application source node determines that the node to be monitored stops, upon detecting that the connection is disconnected and receiving the down notification from the monitoring node, and that a problem occurs in a communication line with the node to be monitored upon detecting that the connection is disconnected and not receiving the down notification from the monitoring node.
