This paper presents a method of measuring traffic of IP multicast streaming, such as IPTV, by using IPFIX/PSAMP. An IP multicast streaming service has recently become one of the popular network services. Yet, the method of IP multicast operation has not been established. In particular, traffic measurement of IP multicast streaming encounters two big challenges, such as monitoring a multicast path tree and QoS performance. There is no method to monitor them continuously in large-scale networks. Hence, we focus on the IPFIX/PSAMP applied in the standardization as a successor of NetFlow/sFlow, and explore the new measurement method and system architecture suitable for larger-scale networks. In addition, we demonstrate experimental results of a prototype measurement system. [ABSTRACT FROM AUTHOR]
