  • Patent number: 7715317
    Abstract: Provided is a flow generation method for Internet traffic measurement. In the flow generation method, dependency between packet collecting time and flow generating time is removed using a virtual timer and a flow generation completion processing interval is controlled to skip by a unit time in response to a user's request. Also, a fragmented packet processing method is selectively used at need and a FIN timeout is applied selectively to a timeout mechanism used in flow generation completion. Thereby, this invention can improve accuracy and efficiency of Internet traffic measurement.
