Abstract
The internet is growing and advancing, and it’s not slowing down. This growth requires a stable backbone to have a seamless communication. To support this ever-growing demand for internet and ubiquity of communication and the depletion of the current IP version IPv6 was born. IETF developed this new version of IP to resolve some issues of IPv4 like scalability, performance, and reliability.
Even though IPV6 was developed a while ago, its application was late mainly because of NAT and other services that let IPV4 continue in the current Internet. But now the new Internet is getting born, for instance Internet of Things (IoT) and other advanced technologies need a more efficient way of communicating so it will not be long before IPV6 takes over. To this end, attempts have begun to transit from IPV4 to IPV6.
However, time and different networks structure, usage and the deep integration of IPV4 makes it hard to automatically transition to IPV6, it may take time and resource to make full transit from IPV4 to IPV6 as the two protocols are not compatible. Even though attempts are done in IPV6 migration, scholars observed that the transition needs a framework that will help in migrating IPV4 to IPV6 with a minimum complication while allowing a room for both to exist until IPV4 network fully transit.
The current ISP in Ethiopia, Ethio Telecom, has an IPV4 only core network. So this research is an attempt to propose a framework that would enable the core network of the ISP to avail and be able to handle IPV6 enabled services. The research follows design science as a methodology, because design science allows as to come up with an artifact and evaluate this artifact in real world situation and to collect data questionnaire was selected. Configurations and designing logical networks are done to demonstrate the framework in a real scenario. GNS3 and NS3 are used to simulate and collect appropriate data. The routing and other configuration done were also be used to evaluate how the new framework is in regards to performance. After evaluating by simulating the framework, the research has found that the framework can be
implemented and also the performance in the services which were selected for the test run smoothly.
The framework which is proposed in this thesis is very important for providing a stepping stone for the migration process of IPV4 based networks and ISP’s. Transitioning the core of a major ISP very hard, it needs time and consderation on all sides because of the outcomes could be devastating if not dealt with care. So this thesis proposes a framework that could reduce the complexity and pave the path for transitioning to IPV6.
