Interface fault diagnosis in ATM switches

Based on the importance of ATM (Asynchronous Transfer Mode) network management and the attractive features of connectionist expert system, an intelligent fault diagnosis system which focuses on interface management of ATM switches is proposed. The designed system consists of two modules: network monitoring and status diagnosis. Network monitoring module is responsible for getting ATM interface information defined by a set of managed objects. Upon receiving these object values from the first model, the status diagnosis module, built by using counter propagation neuron technology, is triggered to detect switch status. From the test results, we believe that the interface fault diagnosis system will be a valuable and potential tool in future network industry
