Abstract:
1. A method of processing traffic of interest in a network, comprising: computing, for the traffic of interest, a baseline profile and a threshold using initial aggregated volume data of the traffic of interest, wherein the baseline profile is computed via a processor using exponential smoothing, wherein the aggregated volume data comprises volume data of network traffic passing through a plurality of network elements of the network aggregated over a time interval having a plurality of time periods; obtaining, by the processor, an aggregated volume count for each particular time period of the plurality of time periods, wherein the aggregated volume count comprises a count of volume of traffic data for each particular period of the plurality of time periods, wherein the aggregated volume count is a count of the network traffic passing through the plurality of network elements of the network; computing, by the processor, for each particular time period of the plurality of time periods, a difference between the aggregated volume count of the particular time period of the plurality of time periods and a particular value of the baseline profile for the same time period; triggering, by the processor, an alarm for each difference that is computed and exceeds the threshold; storing, by the processor, the aggregated volume counts for the plurality of time periods to re-define the aggregated volume data; and modifying, by the processor, the baseline profile and the threshold in accordance with the aggregated volume data being re-defined, wherein the modifying comprises:
