As a cornerstone of the entire network of IPv4 has been very mature. However, due to its own limitations, has been gradually exposed the many problems and shortcomings, therefore IETF IPv6 was designed to replace IPv4. The entire network from IPv4 transition to IPv6 need for a long time, the two networks will coexist for a long time in the future. Therefore, based on the campus network of IPv4 the smooth transition to IPv6 technology is very promising and necessary. This paper will introduce the shortcomings of IPv4 and IPv6 the many advantages of technical analysis of several common transition: Dual-stack technology, the tunnel technology, NAT-PT protocol conversion. Campus Network with the current network deployment, the transition of these technologies will be applied in a reasonable one, to achieve in the current IPv4-based network compatible with IPv6 network. With a view to the future in the future for a long period of time to the campus network in the IPv4 and IPv6 network Network Interconnection.
