Abstract:
1. A network traffic flow monitor system, comprising: a network packet flow collector device for receiving netflow packets associated with a flow of packets at a network connection and generating traffic flow activity data, said traffic flow activity data comprising data used to calculate an associated packet flow rate as a function of time; a filter device, at said flow collector device, configured to generate basis coefficient information from said received netflow packets associated with said flow, said traffic flow activity data including said basis coefficient information; a network packet flow analyzer device for receiving said traffic flow activity data and processing said traffic flow activity data to form signals representing an approximated packet flow rate in time; a synthesis filter device, at said flow analyzer device, responsive to said basis coefficient information received from said flow activity data to configure said synthesis filter device to process said formed signals and reconstruct the associated packet flow rate as a function of time, and, wherein said filter device adapts the netflow packets according to a received network packet flow duration, said network packet flow collector device adapting said basis coefficient data of said filter device according to said network packet flow duration, whereby a reporting of network packet flows is improved.
