Claim Text:
1. A method for performing a corrective action in a communication network, the method comprising: monitoring, by a processor, a health status of a plurality of network elements and a plurality of network routes that are interconnecting the plurality of network elements in the communication network, wherein the communication network is a voice over Internet protocol network, wherein the health status of each of the plurality of network elements and each of the plurality of network routes is monitored via signaling failure alarms that are generated by the plurality of network elements and sent from the plurality of network elements, wherein each of the plurality of network elements is used to support a call initiated by a subscriber in the communication network, wherein each of the plurality of network elements comprises a call signaling network element, and wherein each of the plurality of network routes comprises a call signaling path, wherein the health status of each of the plurality of network elements and the network routes is monitored by a network management system; determining, by the processor, whether a number of the signaling failure alarms received for a network element of the plurality of network elements exceeds a predefined alarm threshold, wherein the predefined alarm threshold is a ratio of a number of blocked calls against a call volume in a predefined period of time; analyzing, by the processor, the signaling failure alarms after it is determined that the predefined alarm threshold is exceeded; and performing, by the processor, the corrective action in the communication network, wherein the corrective action comprises recommending a replacement of a network link.
