Campus Network IPv4to IPv6Transition Technology And Engineering Implementation

Now the development of the Internet is severely restricted because of the depletion of theIPv4address, so it is of great significance for the study of the next-generation Internetprotocol(IPv6protocol). Although the IPv6research has made great achievements,there arestill many problems in IPv4to IPv6transition. So we must realize the communicationbetween IPv4and IPv6using the transition technology.This article first introduced the domestic and foreign current situation of thedevelopment of IPv6, and then compare the similarities and differences between IPv4andIPv6protocols.It describes the three major transition technologies: dual-stack, tunneling andtranslation mechanisms. On the basis of the study of IPv6in universities,this paper designs thenext generation network upgrade scheme based on IPv4/IPv6using the double stack transitiontechnique. This paper identifies the equipment selection program by analyzing the status ofJinan University campus network,the next network construction principles and designrequirements.The program uses the Cisco Catalyst6500Series switches and3560switches todeploy the core layer and convergence layer and access layer device remains unchanged. Itcompleted the IPv6address subnet id field according to analyzing the topology structure andthe physical location of the university of Jinan.In this paper,it uses OSPF to replace theoriginal static routing protocol and OSPFv2can run on existing IPv4network, OSPFv3canrun on the upgraded IPv6network. In the process of campus network upgrading schemeplanning, network security has always been an important technical factors.So based on theresearch of the IPv4/IPv6network technology,this paper determines the IPv6networksecurity deployment plan.Finally, on the basis of the program,the key technologies used in the transition was testedthrough simulation testing and the feasibility of the program is validated.
