PROACTIVE NETWORK-FAULT DETECTION

To improve network reliability & management in today's high-speed comm unication networks, we propose an intelligent system using adaptive st atistical approaches, The system learns the normal behavior (norm) of the network, Deviations from the norm are detected and the information is combined in the probabilistic framework of a Bayes network, The pr oposed system thereby can detect unknown or unseen faults, As demonstr ated on real network data, this method can detect abnormal behavior be fore a fault actually occurs, giving the network management system (hu man or automated) the ability to avoid a potentially serious problem.
