Abstract(in English) The performance monitoring of voice-over-IP (VoIP) traffic is vital for Internet Service Providers (ISPs) which provide a VoIP service with the Internet access services. Identifying degradation in VoIP flows based on the link utilization monitoring becomes increasingly difficult with increasing diversity of the traffic characteristics (burstiness, short duration, constant bit rate, etc.). In this paper, we propose a method for scalabe performance monitoring of VoIP flows distinguished by five tuples. This method extracts the VoIP flows in a lightweight manner, and estimates the packet loss rate and the delay variation by exploiting the features of actual VoIP flows, that is, fixed packet length and fixed inter-packet gaps which are relatively common features among most VoIP flows. Through the evaluation with simulation with trace data of actual traffic, we show that monitoring only 2% or less of the total VoIP flows can accurately estimate the delay variation of the total VoIP flows, while 20% or more of the total VoIP flows are required in order to estimate the packet loss rate.
