Abstract
The network fault manager described herein may include one or more processors configured to detect alarms. For example, the one or more processors may periodically sample rates at which similar events that relate to occurrences on a network arrive, compare the periodically sampled rates to a first threshold, and determine whether a preexisting alarm exists. In response to a number of the periodically sampled rates that exceeded the first threshold within a preceding time window exceeding a second threshold and the preexisting alarm not existing, the one or more processors may assert a first alarm. Otherwise, if the number of periodically sampled rates that exceeded the first threshold within the preceding time window exceeds the second threshold but the preexisting alarm does exist, the one or more processors may maintain the preexisting alarm for a predetermined time period.
