| 中文摘要: |
| 随着IPv4地址资源逐渐耗尽，IPv4向IPv6的全面过渡更加紧迫.现有过渡机制在大规模部署中仍面临着诸多问题需要解决，如缺少统一的评价指标，如何选择合适的过渡方案成为难题.研究并总结了ISP网络中潜在的IPv6过渡场景及典型的过渡机制；提出统一的评价指标，在功能、应用、性能、部署以及安全方面对IPv6过渡机制进行评价比较；依据评价指标，提出ISP网络中核心网和接入网IPv6过渡部署的策略.最后，结合软件定义网络，提出基于SDN架构的IPv6过渡部署考虑. |

| As IPv4 address resources being exhausted, the transition from IPv4 to IPv6 is inevitable and fairly urgent. The existing IPv6 transition techniques encountered several critical issues for large-scale deployment. For example, the lack of unified evaluation criterion makes it hard to select the appropriate transition strategy for a given scenario. This paper investigates and presents potential IPv6 transition scenarios and typical transition mechanisms in ISP networks, with emphasis on the provision of unified evaluation criteria in terms of functionality, applications, performance, deployment and security for IPv6 transition mechanisms and evaluation of these transition techniques based on the provided criteria. In addition, by virtue of the unified evaluation criteria, this study proposes a practical deployment of IPv6 transition strategy in the ISP's core and access networks. Finally, the consideration of IPv6 transition based on the emerging technology such as SDN to ease and accelerate its deployment is presented. |
