摘要： A network-centric modeling mechanism is provided for updating network models in order to mitigate network issues. The network-centric modeling mechanism determines for each component in a plurality of components whether a system parameter in a set of parameters particular to the component has deviated from a predicted system parameter value in a set of predicted system parameter values past a predetermined threshold. Responsive to the system parameter deviating from the predicted system parameter value past the predetermined threshold, the network-centric modeling mechanism generates an event stream indicating a sufficient deviation. The network-centric modeling mechanism determines whether the event stream matches a previous pattern. Responsive to identifying the previous pattern that matches the event stream, the network-centric modeling mechanism preemptively mitigates any related issues in the component or in a related component in the plurality of components using topology-aware indices associated with the previous pattern.

摘要： An apparatus for predicting a network event flood comprises an event rate detector for detecting rates of event emissions from one or more devices; an aggregator for producing an aggregate rate and an aggregate rate trend of the rates of event emissions from a plurality of the devices; a level generator for generating a plurality of levels comprising maximum acceptable event rate values of a plurality of the aggregate rate trends over plural time periods; a storage component for storing the plurality of levels; a comparator for comparing a current aggregate rate trend with at least a selected one of the levels; and a signaller for signalling a predicted event flood responsive to the comparator detecting that the current aggregate rate trend will exceed the at least a selected one of the levels at a first point in time.
