Research And Design Of Campus Network Construction Model Based On IPv6

With the rapid development and wide application of network information technology inthe21st century, the IPv4based computer network gradually exposed such problems as IPaddress shortage and the rapid growth of the routing table. Meanwhile, with the deepening ofChina’s reform of the education system, we had to face a expanding in colleges anduniversities scale,a sharp increase in campus network users, and more and more computernetwork businesses, which reflected such new problems as the network bandwidth bottlenecks,security management and multi-service needs. These problems greatly limits the developmentof the campus network, the IPv6based next-generation campus network construction isimminent.For an example, this paper carried out a systematic theoretical analysis and practicalresearch for a school IPv6campus network construction, firstly, this paper Summarized theIPv6network development and application at home and abroad, secondly, this paper carriedout a systematic analysis and presentation of the IPv6protocol, summarized the mainadvantages of the IPv6protocol and the main problems encountered in the IPv6protocolapplication process, on this basis, this paper carried out a systematic study about IPv6campusnetwork construction planning and cleared the specific programs and content of IPv6campusnetwork construction.Based on the systematic theoretical research of IPv6campus network construction, thispaper finished the specific design and implementation of a school IPv6campus networkconstruction. This paper first cleared the IPv6campus network design principles, and thencombined with the conditions and development goals of the school, this paper completed theconstruction needs analysis of the IPv6campus network, on this basis, this paper finished theoverall design of the IPv6campus network, and finished the implementation from the networklevel, equipment selection, routing policy, address planning, wireless network systems, accesssystems, network management and other aspects, finally this paper carried out IPv6campus network experiments and tests. Finally, based on the analysis of IPsec security protocol，thispaper created an application platform for IPsec security policy, and built an security systemfor IPv6campus network.Overall, the design and implementation of school IPv6campus network provided IPv6access services for the school, which effectively solved the existing problems exposed in IPv4campus network, and also provided IPv6access for users outside school (by setting thetunnel), which provided an access aggregation platform to CERNET2for local colleges anduniversities.
