A Software Defined Approach to Unified IPv6 Transition

摘要

The IPv6 transition has been an ongoing process throughout the world due to the exhaustion of the IPv4 address space. However, this transition leads to costly end-to-end network upgrades and poses new challenges of managing a large number of devices with a variety of transitioning protocols. Recognizing these difficulties, we propose an software defined approach to unifying the deployment of IPv6 in a cost-effective, flexible manner. Our deployment and experiments demonstrate significant benefits of this approach, including low complexity, low cost and high flexibility of adopting different existing transition mechanisms.
