A Polling Based Network Traffic Monitoring Method

Traffic monitoring is an important approach for network research. Traditional methods have some performance bottlenecks so that they are not applicable in high bandwidth and large traffic environment. A polling based traffic monitoring method is proposed and improved by shortening the journeys of packets when packets capture. This method can save much CPU overhead, and improve packets capture efficiency. Experiments show that, comparing with the traditional traffic monitoring method; the polling based method has improved the packet capture capability largely. It can capture packets at line speed in the 1 000 Mbps environment.
