An Enterprise Perspective on IPv6 Transition Mechanisms
Internet Protocol Version 6, also referred to as IPng or the "next generation" protocol, came about through the IETF to replace the current version Internet Protocol, IP Version 4 (IPv4). The Internet Protocol is the standard network layer protocol used by the global Internet and the majority of computer networks worldwide. In addition to a large advantage in address space, networks implementing IPv6 have seen other benefits that include lower run-time costs, lower management and maintenance costs, better connectivity with converged devices, and faster speeds for real-time data such as voice and video. IPv6 also offers increased mobility and integrated security. China, Japan and many other countries have already or are in the process of transitioning to IPv6. This paper attempts to convey an overall of understanding of the protocol, the transition mechanisms to get from IPv4 to IPv6 and the subsequent challenges and benefits. These items are explained in intentionally brief chapters in order to avoid a voluminous and elaborate report. At times examples will be given of work done on internal test labs, while other instances will be cited as a result of external references and accomplishments.
