Abstract (in Japanese) (See Japanese page) 
(in English) 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. To measure the VoIP traffic fluctuation easily, this paper propose measurement of VoIP traffic variance of the interval of the target RTP packets. This variance can be measured by using commercial router and switch. We evaluated the effectiveness of this method using selective sFlow, which has been implemented in a commercial router with 10Gbps IF. And also, this paper presents relationship between the variance of the interval of RTP packets and Voice Quality, such as PESQ score.
