1. A method in a network management system for detecting intermittent network performance problems, comprising the steps of:
- (1) receiving a current problem alert signal from a monitoring point associated with a network facility, said current problem alert signal being generated by said monitoring point based upon an analysis of performance monitoring data observed during a monitoring period;
(2) determining whether said monitoring point has reported a predetermined number of problem alert signals based upon performance monitoring data observed during monitoring periods within a first predefined time period;
(3) initiating a problem handling process if said predetermined number of problem alert signals have been received in said first predefined time period prior to receiving said current problem alert signal in a second predefined time period; and
(4) suppressing an additional problem alert signal that is received during said second predefined time period following said first predefined time period.

Abstract
A system and method for detecting intermittent network performance problems are described herein. The detection process begins upon the receipt of a problem alert signal (PAS). The system then initiates a problem handling process if a predetermined of number of PASs have been received in a predetermined time period prior to receiving the PAS. The system then maintains the problem handling process if additional PASs are received. This system clears the problem and handling processes if no additional PASs are received in a predetermined time period.
