Abstract

A method and system for reporting defects within a network are disclosed. In accordance with an embodiment of the present invention, a method for reporting defects within a network comprises generating a summary alarm by a network element based on defects detected within a network. The method further comprises receiving at the network element a first request for the detected defects within the network from a network management system in response to generation of the summary alarm. The method further comprises reporting the detected defects by the network element in response to the first request from the network management system.

Claims

1. A method for reporting defects within a network comprising:

detecting by a network element that a plurality of defects have occurred within the network;

determining by the network element that the number of defects is greater than a threshold;

generating a single summary alarm by the network element based on the plurality of defects;

sending the summary alarm from the network element instead of an individual defect alarm for each of the plurality of defects;

receiving at the network element a first request from a network management system for the detected defects within the network in response to generation of the summary alarm; and

reporting the detected defects by the network element in response to the first request from the network management system.

2. The method of claim 1, further comprising detecting by the network element a change in the detected defects within the network.

3. The method of claim 1, further comprising generating by the network element a transient condition if a change in the detected defects within the network occurs after the summary alarm is generated.

4. The method of claim 3, further comprising:

receiving at the network element a second request from the network management system for the change in the detected defects within the network in response to the transient condition; and

reporting by the network element the change in the detected defects in response to the second request from the network management system.

5. The method of claim 1, further comprising:

initiating a transient condition timer in the network element; and

generating by the network element a transient condition when the transient condition timer expires if a change in the detected defects within the network occurs after initiation of the transient condition timer.

6. The method of claim 1, further comprising:

saving by the network management system a timestamp associated with the summary alarm; and

generating by the network element a transient condition if a change in the detected defects within the network occurs after the timestamp was saved.

7. The method of claim 1, further comprising:

generating by the network element a first transient condition if a first change in the detected defects within the network occurs after the summary alarm is generated;

saving by the network element a timestamp associated with the first transient condition; and

generating by the network element a second transient condition if a second change in the detected defects within the network occurs after the timestamp was saved.

8. A system for reporting defects within a network, comprising:

a network element comprising at least one network interface that includes one or more physical ports each coupled to a transmission medium that enables the network element to receive data from and transmit data to one or more other network elements, the network element configured to;

detect that a plurality of defects have occurred within the network;

determine that the number of defects is greater than a threshold; and

generate a single summary alarm based on the plurality of defects; and

report the detected defects to a network management system in response to a request from the network management system;

the network management system communicatively coupled to the network element and configured to;

receive the summary alarm from the network element instead of receiving an individual defect alarm for each of the plurality of defects; and

generate a first request to the network element for the detected defects within the network in response to receiving the summary alarm.

9. The system of claim 8, wherein the network element is further configured to report the detected defects by the network element in response to the first request from the network management system.

10. The system of claim 8, wherein the network element is further configured to detect a change in the detected defects within the network.

11. The system of claim 8, wherein the network element is further configured to generate a transient condition if a change in the detected defects within the network occurs after the summary alarm is generated.

12. The system of claim 11, wherein:

the network management system is further configured to;

receive the transient condition from the network element; and

generate a second request to the network element for the change in detected defects within the network in response to the transient condition; and

the network element is further configured to report the change in the detected defects in response to the second request from the network management system.

13. The system of claim 8, wherein the network element is further configured to:

initiate a transient condition timer; and

generate a transient condition when the transient condition timer expires if a change in the detected defects within the network occurs after initiation of the transient condition timer.

14. The system of claim 8, wherein:

the network management system is further configured to save a timestamp associated with the summary alarm; and

the network element is further configured to generate a transient condition if a change in the detected defects within the network occurs after the timestamp was saved.

15. The system of claim 8, wherein:

the network element is further configured to generate a first transient condition if a first change in the detected defects within the network occurs after the summary alarm is generated; and

the network management system is further configured to save a timestamp associated with the first transient condition.

16. The system of claim 15, wherein the network element is further configured to generate a second transient condition if a second change in the detected defects within the network occurs after the timestamp was saved.

17. A network element, comprising:

a processing unit configured to;

detect that a plurality of defects have occurred within a network;

determine that the number of defects is greater than a threshold; and

generate a single summary alarm based on the plurality of defects; and

send the single summary alarm instead of an individual defect alarm for each of the plurality of defects over the network to a network management system;

a network interface comprising one or more physical ports each coupled to a transmission medium that enables the network element to receive data from and transmit data to one or more other network elements, the network interface, associated with the processing unit and configured to;

receive a first request for the detected defects within the network from the network management system in response to the summary alarm; and

report the detected defects in response to the first request from the network management system.

18. The network element of claim 17, wherein the processing unit is further configured to detect a change in the detected defects within the network.

19. The network element of claim 17, wherein the processing unit is further configured to generate a transient condition if a change in the detected defects within the network occurs after the summary alarm is generated.
