ROOT CAUSE ANALYSIS IN A DISTRBUTED NETWORK MANAGEMENT ARCHITECTURE

摘要

A method of determining the root cause of an event in a computer network having a distributed network management architecture including detecting an event at at least one device (300) component (DC) in the network, for each source DC at which an event is detected, finding a data path within the network (310) from the source DC's underlying network element to that of its acquaintance DC where present, identifying as the root cause any of the source DC and the subject DC's in the data path that have detected an event and either do not have an acquaintance or do not have a valid operational state with respect to the acquaintance whereas all other DC's along the data path at lower network layers than the source or subject DC have valid operational states with respect to their acquaintances.
