Method and apparatus for suppressing duplicate alarms
A method and apparatus for suppressing a duplicated alarm in a communications network are described. In one embodiment, at least one alarm message associated with at least one event is received. A determination of whether the at least one event exists in a database is subsequently made. The at least one event is recorded in the database if the at least one event does not exist in the database. Conversely, the at least one alarm message is suppressed if the at least one event exists in the database.
1. A method for processing an alarm message in a communications network, comprising:
receiving the alarm message, wherein the alarm message is associated with an event;
determining if the event exists in a memory;
recording the event in the memory if the event does not exist in the memory; and
suppressing the alarm message if the event exists in the memory.
2. The method of claim 1 , wherein the memory comprises a hash table.
3. The method of claim 1 , further comprising:
forwarding the alarm message to a central management console after the event is recorded in the memory.
4. The method of claim 1 , wherein the event is designated as a duplicate event if a replica of the event exists in the memory.
5. The method of claim 4 , wherein the duplicate event is characterized by an event name, an identical source internet protocol address, an identical destination internet protocol address, an identical source port, an identical destination port, and an identical protocol as compared to the replica.
6. The method of claim 1 , further comprising:
deleting the event from the memory upon an expiration of a predefined time period.
7. The method of claim 1 , wherein the communications network comprises an internet protocol network.
8. A computer readable medium having stored thereon a plurality of instructions, the plurality of instructions including instructions which, when executed by a processor, causes the processor to perform a method for processing an alarm message in a communications network, comprising:
receiving the alarm message, wherein the alarm message is associated with an event;
determining if the event exists in a memory;
recording the event in the memory if the event does not exist in the memory; and
suppressing the alarm message if the event exists in the memory.
9. The computer readable medium of claim 8 , wherein the memory comprises a hash table.
10. The computer readable medium of claim 8 , further comprising:
forwarding the alarm message to a central management console after the event is recorded in the memory.
11. The computer readable medium of claim 8 , wherein the event is designated as a duplicate event if a replica of the event exists in the memory.
12. The computer readable medium of claim 11 , wherein the duplicate event is characterized by an event name, an identical source internet protocol address, an identical destination internet protocol address, an identical source port, an identical destination port, and an identical protocol as compared to the replica.
13. The computer readable medium of claim 8 , further comprising:
deleting the event from the memory upon an expiration of a predefined time period.
14. The computer readable medium of claim 8 , wherein the communications network comprises an Internet protocol network.
15. An apparatus for processing an alarm message in a communications network, comprising:
a processor; and
a computer readable medium in communication with the processor, wherein the computer readable medium has stored thereon a plurality of instructions, the plurality of instructions including instructions which, when executed by the processor, cause the processor to perform a method, comprising:
receiving the alarm message, wherein the alarm message is associated with an event;
determining if the event exists in a memory;
recording the event in the memory if the event does not exist in the memory; and
suppressing the alarm message if the event exists in the memory.
16. The apparatus of claim 15 , wherein the memory comprises a hash table.
17. The apparatus of claim 15 , wherein the method further comprises:
forwarding the alarm message to a central management console after the event is recorded in the memory.
18. The apparatus of claim 15 , wherein the event is designated as a duplicate event if a replica of the event exists in the memory.
19. The apparatus of claim 18 , wherein the duplicate event is characterized by an event name, an identical source Internet protocol address, an identical destination internet protocol address, an identical source port, an identical destination port, and an identical protocol as compared to the replica.
20. The apparatus of claim 15 , wherein the method further comprises:
deleting the event from the memory upon an expiration of a predefined time period.
