全球IPv4地址已分配完毕,IPv4资源耗尽,要将现网海量的IPv4应用和服务迁移到IPv6是一个庞大和繁杂的工程。详细阐述了当前主流的IPv6过渡技术现状,并对各个主流技术进行对比分析,提出了适合不同场景的两条IPv6技术演进路线。
The global IPv4 addresses have been allocated and IPv4 resources are exhausted. To migrate the large number of existing IPv4 applications and services to IPv6 is a huge and complex project. The current status of the mainstream IPv6 transition technology is expounded in detail, and the comparative analysis of various mainstream technologies is made. Two evolution routes of IPv6 technologies are proposed for different scenarios.
