Network management apparatus and method for identifying causal events on a network
First Claim
1. A method for identifying a causal event among a plurality of events detected by a network management station on a network, which causal event is indicative of the underlying cause of more than one of said plurality of events, wherein certain of the events are related wherein the network management station knows the topology of the network, the method performed by said network management station, and comprising the steps of:
- for each related event in the plurality of events, determining the number of devices and/or links between a network causing the event and the network management station, and determining as said causal event, the event for which the determined number of devices and/or links is the fewest.

Abstract
A network management apparatus and method for identifying an event which is indicative of the underlying cause of more than one of a plurality of events detected by a network management station on a network is described in which the management station has knowledge of the topology of the network. Using the topology of the network, the apparatus and method considers the location of the network device causing each event in the plurality of events, and determines as the causal event, the event which has occurred at a location closest to the network management station. The method is preferably implemented in the form of a computer program.

17. On a computer readable medium, a computer program for identifying a causal event among a plurality of events detected by a network management station on a network, which causal event is indicative of the underlying cause of more than one of said plurality of events, wherein certain of the events are related, and wherein the network management station knows the topology of the network, the computer program comprising:
-
program means for each related event determining for each related event the number of devices and/or links between a network device causing the event and the network management station, and program means for determining as said causal event, the event for which the determined number of devices and/or links is the fewest.

18. A network management apparatus for managing a network, comprising a network management station having a processor and memory, the memory storing data representing the topology of the network, wherein the network management station is configured to monitor the network and to generate events in finding predefined event conditions;
- wherein the network management station is further configured to identify a causal event among a plurality of related events generated by the network management station, which causal event is indicative of the underlying cause of more than one of said plurality related events, by;
for each related event, determining the number of devices and/or links between a network device causing the event and the network management station, and determining as said causal event, the event for which the determined number of devices and/or links is the fewest.
- wherein the network management station is further configured to identify a causal event among a plurality of related events generated by the network management station, which causal event is indicative of the underlying cause of more than one of said plurality related events, by;
