Sustainable IPv4 to IPv6 Transition

The next-generation Internet Protocol, initially known as IP Next Generation (Ipng), and then later as IPv6, has been developed by the Internet Engineering Task Force (IETF) to replace the current Internet Protocol (also known as IPv4). To enable the integration of IPv6 into current networks, several transition mechanisms have been proposed by the IETF IPng Transition Working Group. This work examines and empirically evaluates two transition mechanisms, namely IPv6 to IPv4 tunneling and dual-stack mechanism, as they relate to the performance of IPv6. We explore the impact of these approaches on end -to-end user application performance using metrics such as throughput, latency, and host CPU utilization. All experiments were conducted using three dual stack (IPv4/IPv6) routers, an IPv6 router and two ends –stations running Windows 7, loaded with a dual IPv4/IPv6 stack.
