IVI-based Locator/ID Separation Architecture for IPv4/IPv6 Transition

The current Internet is challenged by the IPv4 address depletion. The stateless IPv4/IPv6 translation technology (IVI) is proposed to facilitate IPv4/IPv6 coexistence and transition. The IVI protocol translation involves the address mapping between IPv4 and IPv6, but the address mapping rules still rely on static configuration. In this paper, we propose an IVI-based locator/id separation architecture for IPv4/IPv6 transition. The new architecture provides a scalable address mapping mechanism and extends IVI to support inter-domain networking and host mobility. Through the deployment of this architecture, the Internet would eventually evolve into a pure IPv6 backbone while the IPv4 layer would be separated from the IPv6 network via protocol translation.
