Abstract

An autonomous message transmission method in a manager-to-agent model system including a manager and an agent respectively accommodated in an IP network, comprises transmitting a command/response oriented command based on a connection-oriented protocol to the manager from the agent before transmitting a first autonomous message including a time when starting up a system, and transmitting an autonomous message based on a connectionless protocol when confirming some response to the agent from the manager.

Claims

1. An autonomous message transmission method in a manager-to-agent model system including a manager and an agent respectively accommodated in an IP network, said method comprising:

transmitting a command/response oriented command based on a connection-oriented protocol to said manager from said agent before transmitting a first autonomous message including a time when starting up a system; and

transmitting an autonomous message based on a connectionless protocol when confirming some response to said agent from said manager.

5. An autonomous message transmission method according to claim 1, 2 or 3, wherein the transmission of the command/response oriented command is retried till the response from said manager to said agent is confirmed, and

the autonomous message is transmitted when confirming the response.

6. An autonomous message transmission method according to claim 5, wherein retry count information mapped to the weight of the autonomous message is retained, and

a retry count of the transmission of the command/response oriented command is set changeable based on the weight of the autonomous message.

7. An autonomous message transmission method according to claim 5, wherein retry interval information mapped to the weight of the autonomous message is retained, and

a retry interval of the transmission of the command/response oriented command is set changeable based on the weight of the autonomous message.

8. An autonomous message transmission method according to claim 1, wherein the connectionless protocol is SNMP that supports UDP, and

the autonomous message is TRAP based on SNMP.

9. An autonomous message transmission method according to claim 1, wherein the connection-oriented protocol is Telnet that supports TCP.

2. An autonomous message transmission method in a manager-to-agent model system including a manager and an agent respectively accommodated in an IP network, said method comprising:

managing communications with said manager when normally operated after starting up a system;

transmitting a command/response oriented command based on a connection-oriented protocol before said agent transmits an autonomous message based on a connectionless protocol to said manage if a predetermined time elapses since a message was finally received from said manager or transmitted to said manager; and

transmitting the autonomous message when confirming some response to said agent from said manager.

3. An autonomous message transmission method in a manager-to-agent model system including a manager and an agent respectively accommodated in an IP network, said method comprising:

monitoring a signal receiving interval in periodic monitoring in said agent when said manager periodically monitors said agent;

transmitting a command/response oriented command based on a connection-oriented protocol before transmitting an autonomous message based on a connectionless protocol when judging that the signal for the periodic monitoring is not received; and

transmitting the autonomous message when confirming some response to said agent from said manager.

4. An autonomous message transmission method in a manager-to-agent model system including a manager and an agent respectively accommodated in an IP network, said method comprising:

transmitting an autonomous message based on a connectionless protocol to said manager from said agent; and

judging whether to transmit a command/response oriented command based on a connection-oriented protocol in accordance with a weight of the predefined autonomous massage before transmitting the autonomous message based on the connectionless protocol.

10. An agent-resided system comprising:

a module transmitting a command/response oriented command based on a connection-oriented protocol to a manager via an IP network before transmitting a first autonomous message including a time when starting up said system; and

a module transmitting an autonomous message based on a connectionless protocol when confirming some response from said manager.

14. An agent-resided system according to claim 10, 11 or 12, wherein the transmission of the command/response oriented command is retried till the response from said manager to said agent is confirmed, and

the autonomous message is transmitted when confirming the response.

17. An agent-resided system according to claim 10, wherein the connectionless protocol is SNMP that supports UDP, and

the autonomous message is TRAP based on SNMP.

18. An agent-resided system according to claim 10, wherein the connection-oriented protocol is Telnet that supports TCP.

11. An agent-resided system comprising:

a module managing communications with a manager via an IP network when normally operated after starting up said system;

a module transmitting a command/response oriented command based on a connection-oriented protocol before transmitting an autonomous message based on a connectionless protocol to said manage if a predetermined time elapses since a message was finally received from said manager or transmitted to said manager; and

a module transmitting the autonomous message when confirming some response from said manager.

15. An agent-resided system according to claim 14, further comprising a module retaining retry count information mapped to the weight of the autonomous message, and setting changeable a retry count of the transmission of the command/response oriented command on the basis of the weight of the autonomous message.

16. An agent-resided system according to claim 14, further comprising a module retaining retry interval information mapped to the weight of the autonomous message, and setting changeable a retry interval of the transmission of the command/response oriented command on the basis of the weight of the autonomous message.

12. An agent-resided system comprising:

a module monitoring a signal receiving interval in periodic monitoring in said agent when a manager executes periodic monitoring via an IP network;

a module transmitting a command/response oriented command based on a connection-oriented protocol before transmitting an autonomous message based on a connectionless protocol when judging that the signal for the periodic monitoring is not received; and

a module transmitting the autonomous message when confirming some response from said manager.

13. An agent-resided system comprising:

a module transmitting an autonomous message based on a connectionless protocol to a manager via an IP network; and

a module judging whether to transmit a command/response oriented command based on a connection-oriented protocol in accordance with a weight of the predefined autonomous massage before transmitting the autonomous message based on the connectionless protocol.
