The Research of Network Transitional Technology fromIPv4 to IPv6

摘要

Internet has experienced decades of rapid development, as the cornerstone of the entire network the IPv4 also has become very mature. However, due to its own limitations, it has been gradually exposed many shortcomings, so IPv6 designed by IETF as an alternative to IPv4.This paper put forward three major transition technologies: dual-stack (Dual Stack), tunnel (Tunnel), the address protocol conversion (NAT-PT) and the experimental model of the three technologies, which provide a useful reference for future IPv6 network design.
