Abstract:

This paper presents the design and implementation of a simulator comprising the following components: a rule database, a topology generator, a failure generator, and an alarm generator. The topology generator produces network topologies to simulate various network conditions, while the failure generator generates simulated failures. Subsequently, the alarm generator utilizes the rule database to generate corresponding alarm data. The generated data structures include failures/alarms, alarm flows, alarm chains, and alarm correlation trees. Furthermore, a test case is introduced to validate the accuracy of the simulator.
