Research on the Next-Generation Internet Transition Technology

摘要

The large IPv6 address space enables the study on network addresses in a network environment, which ensures the construction of a secured and trusted China Next Generation Internet (CNGI), it is a tested for Next Generation Internet (NGI) applications. This paper describes two of the major transition technology and discusses their applicability and uses. The intra-site automatic tunnel addressing protocol (ISATAP) connects IPv6 hosts/routers over IPv4 networks. The 6to4 tunnel addressing Protocol connects IPv4 hosts/routers over IPv6 networks. With a useful set of these tools in place, IPv6 could be deployed at a much greater speed and with ever-greater confidence for us.
