Abstract

A method and system for masking defects within a network are disclosed. In accordance with an embodiment of the present invention, a method for masking defects within a network comprises detecting by a service entity defects within a network. The method further comprises determining a number of detected defects associated with a network component included in the network. The method further comprises generating by the network component a summary alarm if the number of detected defects within the network is greater than a first threshold.

Claims

1. A method for masking defects within a network, comprising:

detecting by a service entity defects within a network;

determining a number of detected defects associated with a network component included in the network; and

generating by the network component a summary alarm if the number of detected defects within the network is greater than a first threshold.

2. The method of claim 1, further comprising clearing by the network component the summary alarm if the number of defects is less than a second threshold.

3. The method of claim 2, wherein the first threshold is greater than the second threshold.

4. The method of claim 1, wherein the network component comprises a network element, a network interface, a logical interface or a port.

5. A method for masking defects within a network, comprising:

detecting by a service entity defects within a network;

determining a first number of detected defects associated with a first network component included in the network; and

generating by the first network component a first summary alarm if the first number of detected defects within the network is greater than a first upper threshold.

6. The method of claim 5, further comprising clearing by the first network component the first summary alarm if the first number of defects is less than a first lower threshold.

7. The method of claim 5, further comprising:

generating an individual defect alarm by the first network component for each of the detected defects; and

clearing each individual defect alarm when the first summary alarm is generated.

8. The method of claim 5, further comprising:

determining a second number of detected defects associated with a second network component that includes the first network component;

generating a second summary alarm associated with the second network component if the second number of detected defects associated with the second network component is greater than a second upper threshold for the second network component; and

clearing the first summary alarm associated with the first network component when the second summary alarm is generated.

9. The method of claim 8, further comprising clearing by the second network component the second summary alarm if the second number of defects is less than a second lower threshold.

10. The method of claim 9, wherein:

the second upper threshold is approximately twice the first upper threshold; and

the second lower threshold is approximately twice the first lower threshold.

11. The method of claim 8, further comprising:

generating an individual defect alarm by the second network component for each of the detected defects; and

clearing each individual defect alarm when the second summary alarm is generated.

12. A network element, comprising:

a service entity configured to detect defects within a network;

a first network component including the service entity; and

a processing unit communicatively coupled to the first network component, the processing unit configured to;

determine a first number of defects associated with the first network component; and

generate a first summary alarm if the first number of detected defects associated with the first network component is greater than a first upper threshold.

13. The network element of claim 12, wherein the processing unit is further configured to clear the first summary alarm if the first number of detected defects associated with the first network component is less than a first lower threshold.

14. The network element of claim 12, wherein the processing unit is further configured to:

receive detected defects from the service entity;

generate an individual defect alarm for each of the detected defects; and

clear each individual defect alarm when the first summary alarm is generated.

15. The network element of claim 12, further comprising a second network component including the first network component and communicatively coupled to the processing unit.

16. The network element of claim 15, wherein:

the first network component comprises a logical interface; and

the second network component comprises a network interface.

17. The network element of claim 15, wherein the processing unit is further configured to:

determine a second number of defects associated with the second network component;

generate a second summary alarm associated with the second network component if the second number of detected defects associated with the second network component is greater than a second upper threshold for the second network component; and

clear the first summary alarm associated with the first network component when the second summary alarm is generated.

18. The network element of claim 17, wherein the processing unit is further configured to clear the second summary alarm if the second number of defects is less than a second lower threshold.

19. The network element of claim 18, wherein:

the second upper threshold is approximately twice the first upper threshold; and

the second lower threshold is approximately twice the first lower threshold.

20. The network element of claim 17, wherein the processing unit is further configured to:

receive detected defects from the service entity;

generate an individual defect alarm for each of the detected defects; and

clear each individual defect alarm when the second summary alarm is generated.
