【摘要】 随着21世纪信息技术的飞速发展,互联网普及程度越来越高,互联网用户逐渐增多,IPv4地址资源已经越来越紧缺,IPv6地址的出现能够从根本上解决这一问题。然而,从IPv4过渡到IPv6是一个漫长的过程,目前主流的过渡技术有双栈、隧道以及翻译技术3种,相关技术都面临着如何选择合适的过渡方案,如何解决用户迁移,如何进行设备改造等难题。软件定义网络作为一种新型的网络架构,将网络设备的控制平面和数据平面分离开,通过集中的控制器对底层网络设备的行为进行控制,对IPv6的平稳过渡具有重要指导意义。更多还原

【Abstract】 With the rapid development of information technology in the 21st century,the popularity of Internet is getting higher and higher,the number of Internet users is increasing,and the IPv4 address is becoming more and more scarce.The emergence of IPv6 address can fundamentally solve the problem of shortage of current IPv4 address resources.However,the transition from IPv4 to IPv6 is a long process,the current mainstream transition technology hasDual Stack,tunnels and translation technology three,these technologies are faced with how to choose the appropriate transition program,how to solve the user migration,equipment transformation and so on.Software-Defined Networking(SDN),as a new network architecture,separates the control plane and data plane of the network equipment,controls the behavior of the underlying network equipment through a centralized controller,and makes a smooth transition to IPv6 has important guiding significance.更多还原
