Based On The Campus Network Ipv4 To Ipv6 Smooth Transition

The computer networks, especially the rapid development of Intemet brings lots ofvalues for society today and it almost has covered all kinds of fields. But the main protocolof Internet, IPv4 has not satisfied the need of the development in future because it has beenlimited by the defects in present system,IPv6 was devised to substitute IPv4 by IETF.The entire transition from IPv4 to IPv6 will spend much time, and the coexistence willIast for a long period of time. Campus network is also confronted with the samequestion.In this situation, the research on the smooth trasmition from IPv4 to IPv6 is ofnecessity and prospect.In the thesis, we compare IPv4 with IPv6, introduce the fundament characteristics ofIPv6, analyse some varieties of familiar transition technique: tunnel technique, Dual stackand NAT-PT Network Address Translation Protocol Translation. Combined with thecampuse network dispose, these transition techniques are operated reasonably, to apply theIPv6 compatibly in current IPv4 network. In the future, the users could connect and visitmutually between IPv4 and IPv6.
