Cpmstrict Brpadband Network Platform In Use Of IPV6Protocol

The success of Internet has brought great changes to human’s life, and its impact has penetrated all parts of the society Ai the same time, the development of Internet has become an important part of the national modernization construction, which has produced grand economic and social benefit. However with the Internet application evolution, more and more shortcomings have been exposed in the practice of the current IPv4based Internet:the limited address space, low efficiency of routing choice, lack of service quality assurance and security, which resulted in more effort put in IPv6technology.The construction and testing of CNGI have been performed by China Telecom. CNC、China Unicom and Chinese Academy of science have united to build CNGI, which has been constructed in Beijing, Shanghai, Guangzhou, Shenyang, Harbin, Chengdu, Lanzhou. All these have provided the orientation and business motility for our country’s IPv6development.We will build Heilongjiang Wideband Network using IPv6technology according to the strategy of CNC IPv6and status of Heilongjiang China Unicom Internet. Referring to the latest research material and characteristics of Heilongjiang Internet, the article will do some research on Network layout, Device Selection, Transition from IPv4to IPv6, Service Access etc. And we will carries on the test to the network to get the performance parameter of The IPv6technology and the network, laying the foundation found for the maintenance work and the next step large-scale commercial.
