Abstract

A system and method of guaranteeing the delivery of SNMP traps in a computer network. In an exemplary embodiment, the method receives SNMP Traps at a trap concentrator, which bundles the traps using a guaranteed delivery data transmission protocol. The trap concentrator further transmits the bundled traps across a network to a trap echoer, which unbundles the traps and transmits their data content to a trap processor. In exemplary embodiments, the trap concentrator recognizes if attempted trap transmission to the trap echoer fails, and if so, stores the bundled traps in a cache until they can be retransmitted in their original sequence.

Claims

1. A method of guaranteeing the delivery of SNMP traps in a network, comprising:

receiving at least two SNMP traps at a trap concentrator;

bundling the SNMP traps using a guaranteed delivery data transmission protocol;

transmitting the bundled traps to a trap echoer; and

unbundling the traps and transmitting their data content to a trap processor.

2. The method of claim 1, wherein the trap echoer and the trap processor are colocated.

3. The method of claim 1, wherein the guaranteed delivery data transmission protocol is TCP.

4. The method of claim 1, wherein the trap concentrator is connected to trap originators via a high confidence LAN.

5. The method of claim 1, wherein if transmission of a bundled trap by the trap concentrator fails, the trap concentrator caches the bundled trap and resends the bundled trap at a later time.

6. The method of claim 1, wherein the traps are sent from the trap echoer to the trap processor using a guaranteed delivery data transmission protocol.

7. The method of claim 1, where for each message received by the trap concentrator, the message is packaged for transport and placed in a processing queue.

8. The method of claim 7, wherein:

if a current trap echoer is available, the message is sent to a current trap echoer;

if the current trap echoer is not available, the message is sent to a secondary trap echoer;

and if no trap echoer is available, the message is placed in a queue.

9. The method of claim 1, wherein SNMP traps are received at a primary trap concentrator and at a secondary trap concentrator;

wherein the secondary trap concentrator continually monitors the primary SNMP trap concentrator to ensure it is in an operational state; and

wherein if the secondary trap concentrator senses that the primary trap concentrator is not in the operational state, the secondary trap concentrator actively sends SNMP traps to the trap echoer.

10. A system for guaranteeing the transmission of monitoring messages across a network to a monitoring application, comprising:

a monitoring message concentrator which is connected to and receives monitoring messages from computing equipment, the monitoring message concentrator transmitting received messages across a network to a message echoer using a standards-based guaranteed delivery data transmission protocol;

a monitoring message echoer coupled to the monitoring message concentrator which receives the transmitted messages and further transmits the data content of the messages to a monitoring message processor; and

a monitoring message processor coupled to the monitoring message echoer which implements a monitoring application.

11. The system of claim 10, further comprising a second monitoring message concentrator redundantly coupled with the first monitoring message concentrator to provide redundancy protection for the first monitoring message concentrator.

12. The system of claim 10, where the standards-based guaranteed delivery data transmission protocol is TCP.

13. The system of claim 10, wherein the monitoring messages from computing equipment are sent from the computing equipment using a standards-based data transmission protocol without guaranteed delivery.

14. The system of claim 10, where the monitoring messages from computing equipment are sent from the computing equipment as SNMP traps.

15. A computer program product comprising a computer usable medium having computer readable program code means embodied therein, the computer readable program code means in said computer program product comprising means for causing a computer to:

receive at least two SNMP traps at a trap concentrator;

bundle the SNMP traps using a guaranteed delivery data transmission protocol; and

transmit the bundled traps to a trap echoer;

unbundle the traps and transmit their data content to a trap processor.

17. The computer program product of claim 15, wherein if a current trap echoer is available, the message is sent to the current trap echoer;

if a current trap echoer is not available, the message is sent to a secondary trap echoer; and

if no trap echoer is available, the message is placed in a queue.

18. A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform a method of guaranteeing the delivery of SNMP traps in a network, said method comprising:

receiving at least two SNMP traps at a trap concentrator;

bundling the SNMP traps using a guaranteed delivery data transmission protocol; and

transmitting the bundled traps to a trap echoer; and

unbundling the traps and transmitting their data content to a trap processor.

16. The computer program product of claim 18, wherein the guaranteed delivery data transmission protocol is TCP, and where if transmission of a bundled trap by the concentrator fails, the trap concentrator caches the bundled trap and resends the bundled trap at a later time

19. The program storage device of claim 18, where the guaranteed delivery data transmission protocol is TCP, and where if transmission of a bundled trap by the concentrator fails, the trap concentrator caches the bundled trap and resends the bundled trap at a later time.

20. A method of guaranteeing the delivery of monitoring messages in a network, comprising:

receiving at least two monitoring messages at a message concentrator;

bundling the monitoring messages using a guaranteed delivery data transmission protocol; and

transmitting the bundled monitoring messages to a message echoer;

unbundling the monitoring messages and transmitting their data content to a monitoring message processor.
