A Tunnels-Between-Hosts Based Method for IPv4 Application over Native IPv6 Network

Along with the development of IPv6, native IPv6 networks will begin to appear. It would be helpful if we can provide an effective mechanism for existing IPv4- only applications to work in those native IPv6 networks. In this paper, we analyze the problems of some current transition methods, and present a new mechanism based on Tunnels-Between-Hosts. Our strategy is to provide the IPv4-only application with a temporary IPv4 "virtual address", which is negotiated directly between two communicating hosts using IPv6. We give a detailed description of our mechanism and compare it with some other mechanisms.
