Analysis of IPv6 Transition Technologies

Currently IPv6 is extremely popular with companies, organizations and Internet service providers (ISP) due to the limitations of IPv4. In order to prevent an abrupt change from IPv4 to IPv6, three mechanisms will be used to provide a smooth transition from IPv4 to IPv6 with minimum effect on the network. These mechanisms are Dual-Stack, Tunnel and Translation. This research will shed the light on IPv4 and IPv6 and assess the automatic and manual transition strategies of the IPv6 by comparing their performances in order to show how the transition strategy affects network behaviour. The experiment will be executed using OPNET Modeler that simulates a network containing a Wide Area Network (WAN) , a Local Area Network (LAN), hosts and servers. The results will be presented in graphs and tables, with further explanation. The experiment will use different measurements such as throughput, latency (delay), queuing delay, and TCP delay.
