互联网专线双栈改造方案的研究

Research on transformation scheme of double stack of internet dedicated line

随着互联网技术的演进,IPv4原理的设计缺陷越加明显,这些理论缺陷制约了IP数据通信和网络应用技术的发展,相比IPv4的缺陷,IPv6从本质上解决IPv4网络中存在的问题。互联网专线业务对IP地址需求量多且要求相对较高。一般情况下互联网专线需对外提供业务支持,如Web、FTP等。同时因网络强国战略的推进,国内IPv6改造工作拉开序幕,骨干网均已支持IPv6网络。基于IPv4的缺陷、政府政策及现网情况,提出互联网专线IPv4/IPv6双栈改造的方案。

With the evolution of Internet technology, the design defects of IPv4 principle become more and more obvious. These theoretical defects restrict the development of IP data communication and network application technology. Compared with the defects of IPv4, IPv6 essentially solves the problems existing in IPv4 network. Internet dedicated line services have a high demand for IP addresses. In general, dedicated Internet lines need to provide external services, such as Web and FTP. At the same time, due to the promotion of the network power strategy, the domestic IPv6 transformation began, the backbone network has supported IPv6 network. Based on the defects of IPv4, government policy and current network situation, this paper puts forward a scheme of IPv4/IPv6 double stack transformation for Internet dedicated line.
