....or layer failed may initiate automated recovery, notify the system administrator, and or open a problem record. Communication systems are frequently modeled using a dependency graph whose directed edges indicate that the entity at the tail of an edge depends on the entity at the head of the edge [8, 15]. The network impact graph created by reversing the edges of the dependency graph shows which entities may fail because of the failure of another entity [8] It may be observed that failure symptoms propagate along both dependency and impact graph edges. For example, layer two s ability to form a ....

.... 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 combination of propositions about the current set of received alarms and the ....
