One of the technologies to improve QoS performance is IP Multimedia Subsystem (IMS) which is a technology that providesbase on IP application equipped with QoS facility. The commonly used Internet Protocol (IP) network today is IPv4 but with 32 bit addressing capacity on IPv4 it is impossible to meet the growing use of the internet in the future. Then developed addressing IPv6 which is a 128 bit address capacity protocol which can certainly be used as a replace ment solution IPv4 addressing. In this research, performance testing of VoIP IMS service using IPv network, and analysis method in this research is to compare the performance of VoIP IMS service on IPv6 network with IPv4 network. The application used in this research is Open IMS Core as server and GNS3 to run network topology. From the result QoS still meets the TIPHON TS 101 329-2 standard for throughput parameter obtained 21377.5046 bps on IPv4 network and 21019.9786 bps on IPv6 network , for delay obtained 19.9983 ms on IPv4 network and 20.2512 ms on IPv6 network, for jitter obtained 13.5704 ms on IPv4 network dan 13.6140 ms on IPv6 network,and for packet loss obtained 0% on IPv4 network and 0.1180% at bacground traffic 10 Mbps, 0.1663% at bacground traffic 15 Mbps, 1.0447 % at bacground traffic 20 Mbps on IPv6 network. From the result, VoIP services based IMS still run well on the IPv6 network. Keywords : Voice over Internet Protocol, IP Multimedia Subsystem, IPv6, QoS.} }
