Abstract
Root cause analysis in a communication network includes eliminating candidate events using a computer-implemented method, comprising creating a virtual network model that describes nodes and links of the network at a plurality of time periods; receiving from the network a first event that indicates a problem in the network; receiving a set of second events comprising candidates for a root cause of the first event; determining a network topological indicator from the first event; determining a network implication of the first event based on the topological indicator; based on the network implication and a time value of the first event, retrieving data from the virtual network model that indicates a path between nodes associated with the first event at a time at which the first event occurred; removing, from the set of second events, all events that are not on the path between devices associated with the first event.
