Scenario generation based on SLA requirements Techniques to tune threshold values Threshold violations and system bottleneck prediction Support for uncertainty and lost events 13 6 Related work In the past various event correlation techniques were proposed including rule based systems [18, 26], model based reasoning systems [13, 21] model traversing techniques [14, 15] case based systems [17] fault propagation models [9, 16] and the code book approach [27] Rule based systems are composed of rules (productions) of the form conclusion if condition. The condition part is a logical ....
....systems [17] fault propagation models [9, 16] and the code book approach [27] Rule based systems are composed of rules (productions) of the form conclusion if condition. The condition part is a logical combination of propositions about the current set of received alarms and the system state [18, 26]; the conclusion determines the state of correlation process. The operation of the system is controlled by an inference engine, which in fault management applications typically uses a forward chaining inference mechanism [18, 21] Rule based systems are believed to lack scalability, to be ....

This paper focuses on non deterministic event correlation which is ....

....within an alarm correlation engine using the attached knowledge base, and actions are taken care of by action processor. Other alarm correlation and filtering systems for telecommunication network management have been presented, e.g. in [GHJ 89, GALU95, JW93, JW95, JP93, Nyg95, BCFK95, Haj96, WBES98] Given correlation patterns and actions, and a sequence S of alarms, an alarm correlation process continuously observes the incoming alarm sequence S, considers the last time window on S, and executes the actions associated with the patterns that match the window; for an example, see Example ....
