Abstract :
We present a method of measuring VoIP traffic fluctuation by using netflow or sFlow. As the traffic of critical applications such as VoIP has increased in backbone networks, network operators need to measure the QoS performance of traffic in real networks more easily and passively. We have studied the delay and fluctuation of VoIP traffic in a real network and focused on traffic fluctuation that can be measured at one observation point. We evaluated the effectiveness of this method using selective sFlow, which has been implemented in a commercial router
