Abstract

A management system includes an application source node that applies for subscription of alive and dead state information to a node to be monitored, a node to be monitored that interconnects with the application source node and makes a request to a 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 when receiving the subscription application, and a monitoring node that monitors the node to be monitored when receiving the request from the node to be monitored and makes a notification to the application source node when a response from the node to be monitored stops. The application source node determines that the node to be monitored stops when communication with the node to be monitored is disconnected and the notification is received from the monitoring node.

Claims

1. A management system comprising:

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

a node to be monitored that interconnects with the application source node and makes a request to a 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 when receiving the subscription application; and

a monitoring node that monitors the node to be monitored when receiving the request from the node to be monitored and makes a notification to the application source node when a response from the node to be monitored stops,

wherein the application source node determines that the node to be monitored stops when communication with the node to be monitored is disconnected and the notification is received from the monitoring node.

2. The management system according to claim 1,

wherein the application source node, the node to be monitored, and the monitoring node are nodes on an overlay network using a distributed hash.

3. The management system according to claim 1,

wherein the application source node determines that a problem occurs in a communication line with the node to be monitored when communication with the node to be monitored is disconnected and the notification is not received from the monitoring node.

4. A management apparatus comprising:

a subscription application unit that applies for subscription of alive and dead state information to a node to be monitored;

a monitoring request unit that interconnects with an application source node and makes a request to a node whose routing table includes a node of the management apparatus for monitoring the node of the management apparatus and notifying the application source node of a monitoring result when receiving an application of subscription from another node;

a monitoring unit that monitors, when receiving a request from another node to monitor the another node and notify the application source node of a monitoring result, the another node and makes a notification to the application source node when a response from the another node stops; and

a determination unit that determines that the node to be monitored stops when communication with the node to be monitored is disconnected and a notification is received from a monitoring node that monitors the node to be monitored.

5. A management method comprising:

applying, by an application source node, for subscription of alive and dead state information to a node to be monitored;

interconnecting, by the node to be monitored, with the application source node and making a request to a 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 when receiving the subscription application;

monitoring, by a monitoring node, the node to be monitored when receiving the request from the node to be monitored and making a notification to the application source node when a response from the node to be monitored stops; and

determining, by the application source node, that the node to be monitored stops when communication with the node to be monitored is disconnected and the notification is received from the monitoring node.

6. A computer-readable recording medium having stored therein a management program causing a computer to execute a process comprising:

applying for subscription of alive and dead state information to a node to be monitored;

interconnecting with an application source node and making a request to a node whose routing table includes a node of the computer for monitoring the node of the computer and notifying the application source node of a monitoring result when receiving the subscription application from another node;

when receiving a request from another node to monitor the another node and notify the application source node of a monitoring result, monitoring the another node and making a notification to the application source node when a response from the another node stops; and

determining that the node to be monitored stops when communication with the node to be monitored is disconnected and a notification is received from a monitoring node that monitors the node to be monitored.
