对网络IPv6技术的运用及升级改造方案的思考

Thinking about the Application of Network IPv6 Technology and Upgrading Scheme

基于互联网协议第四版(IP v4)的全球互联网面临网络地址消耗殆尽、服务质量难以保证等制约性问题,IPv6相对于IPv4拥有海量的地址表、高效的转发能力、即插即用、安全报文机制等优势,是全球公认的下一代互联网商业应用解决方案。我国基础电信企业网络基础设施能力已全面就绪,具备全国范围服务能力,并开启IPv6承载服务,移动和固定终端已经全面支持IPv6,随着政府大力推进,企业IPv6改造刻不容缓。介绍了IPv6的相关技术和协议,并分析目前企业升级改造中常用的几种方案(隧道方案、双栈方案、地址转换方案),针对不同方案提出不同的应用场景,同时提出了新建IPv6切实可行的方案,并总结IPv6未来发展的优势。

Compared with IPv4,IPv6 has many advantages,such as massive address table,efficient forwarding ability,plug and play,secure message mechanism and so on.With the vigorous promotion of the government,the transformation of enterprise IPv6 is urgent.This paper introduces the related technologies and protocols of IPv6,and analyzes several commonly used schemes in the current enterprise upgrading and transformation,puts forward different application scenarios for different schemes,and puts forward feasible schemes for the new IPv6,and summarizes the advantages of the future development of IPv6.
