Performance evaluation of applications in manual 6in4 tunneling and native IPv6/IPv4 environments

6in4 is the IPv4 to IPv6 migration technique that uses tunneling to encapsulate IPv6 packets over configured IPv4 communication links. This paper attempts to evaluate and compare performance parameters like Throughput, IP End-to-End Delay and Response Time of different applications running on the internet in IPv4, IPv6 and 6in4 manual tunneling environments. The applications that we are modeling are Database Application, Web Browsing, Video conferencing, Voice Communications and Remote Login. This paper aims to evaluate the performance of these internet applications in three different networks. The results of the study will be important for network administrators and various Internet Service Providers (ISP) for planning of IPv6 migration networks. OPNET Modeler ver. 14.5. has been used for simulation study. The networks that have been modeled consist of different components like client workstations, routers, servers and network backbones.
