Patent ID: 7881210

Claim:
A method for identifying a label distribution protocol flapping event in a communication network, comprising: counting via a processor a total number of label distribution protocol session up events, a total number of label distribution protocol session down events, a total number of link up events, and a total number of link down events within a predetermined time interval; and determining an occurrence of a label distribution protocol flapping event using the plurality of total numbers, wherein the determining comprises: evaluating a condition of whether: a) the total number of label distribution protocol session up events is greater than a threshold, and the total number of label distribution protocol session up events is greater than the total number of link up events, and the total number of label distribution protocol session down events is greater than 0, or b) the total number of label distribution protocol session down events is greater than the threshold, and the total number of label distribution protocol session down events is greater than the total number of total link down events and the total number of label distribution protocol session up events is greater than 0, is true; and generating an alarm to indicate the label distribution protocol flapping event if the condition is true.
