Abstract
Abstract A process and system is disclosed for determining automatically and dynamically the correct time segment during which a switch or components of a switch receive peak traffic from a communications network. The process collects traffic data regarding the usage of a selected switch or selected switch components. The traffic data is collected over a selected journalling period (e.g., 30 days), which is periodically updated with new traffic data to maintain a journal of the most recent 30 days of collected traffic data. Collected traffic data is filtered to remove aberrant or corrupting data. An average peak usage segment for all of the segments of the journalling period is selected from the remaining filtered traffic data. By regularly adding new data to and removing old data from the journal, the resulting moving window will reflect recent changes in peak usage. Regularly (e.g., daily) selecting the average peak usage segment detects such changes quickly, with the result that the process of the present invention dynamically reacts to and determines changes in the peak usage segment for particular switch components. Peak usage segments and associated traffic data determined and collected by the present invention result in improved network traffic engineering. A system is disclosed for collecting, processing and evaluating traffic data in order to engineer network elements for optimal traffic flow.
