Abstract: This paper describes a knowledge-based system developed for monitoring and fault localisation in a wide area network. The system incorporates some of the network operators' and manager's knowledge on localising faults by using the structure of the network and correlating events. This paper describes the overall system structure. It focuses on the Event Handler modules describing its submodules and data representation. We also show how this knowledge and its control map onto a blackboard architecture.
