基于IPv4向IPv6过渡的IP追溯技术研究

摘要

随着IPv4地址的耗尽及IPv6网络的加速部署,将面临IPv4网络和IPv6网络长期共存的局面.目前学术界和工业界提出了多种IPv4向IPv6过渡的技术,这些过渡技术的复合使用将增加IPv4/IPv6混合网络的复杂性,给安全事件的处理和追溯带来了新的挑战,因此复杂过渡网络环境中的IP追溯问题亟待解决.对IP地址安全管理体系下的IP地址的可追溯性及IP追溯技术的最新研究进展进行了综述,同时对IPv4/IPv6混合网络中的IP追溯问题的可能解决方案进行了深入的探讨和分析,最后阐述了IP追溯技术所面临的新挑战,指出了未来研究的方向.%With the IPv4 address exhaustion and the IPv6 networks deployment, it will confront the situation that IPv4 net-works and IPv6 networks will coexist for a very long time. At present, there have been a variety of proposed mechanisms for IPv4 to IPv6 transition, the deployment of these technologies will increase the complexity of IPv4/IPv6 hybrid network and bring new challenges for handling and traceback security incidents. Therefore, IP traceback problems in IPv4 to IPv6 transition network environments need to be solved quickly. This paper reviewed IP address traceability under IP address safety manage-ment system and the recent evolvement of IP traceback technologies. Then gave an in-depth discuss and analysis to possible so-lutions for IP traceback in the IPv4 to IPv6 transition environments. In the end, elaborated on new challenges that IP traceback technologies faced, and discussed the future trend of possible research.
