The Design Of Next Generation Campus Networkd Based On IPv6

With the rapid growth of computer networking technology, the TCP/IP protocol which acts as Internet foundation stone is preceding an unprecedented change than ever before. The wedge that leads this transform is a number of deficiencies when IPv4 protocol faces up to the requirement of Internet development. In order to cope with this issue, people think to replace IPv4 by IPv6. Since IPv6 protocol has many new merits such as the great capacity for address, group broadcast, neighbor detect, automatic scheme as so on. Nevertheless, a question comes up that How to carry out smooth transition from IPv4 to IPv6 along with How to organize the IPv6 at the existing IPv4 network base, which these papers is going to cover over.First of all, in this paper, the author collects and analyzes the latest domestic-overseas information about the transition from IPv4 to IPv6, and studies IPv6's new merits. Then the author depicts the modules, traits as well as routed and routing protocols based on IPv6.whereafer, through the analysis in customary campus network structure, We are going to provide the network upgrade scheme, the method of deploying the coexisting policy connected IPv4/IPv6 in the process of transition, and the introduction about access connection of IPv6 tunnel techniques. With the IPv6 simulator's experimental platform, in the purpose of revealing the IPv6 merits, based on DR existing IPv4 campus network, the implementations and authentications are evolved into the development of IPv6 layout and construction.
