移动IPv4/IPv6的虚拟机迁移过渡框架

为充分利用IPv4/IPv6异构网络资源建设云计算基础平台,满足云计算平台的资源需求,设计了一种基于隧道技术、前缀管理、地址池管理协作及移动IP的IPv4/IPv6虚拟机迁移过渡框架。该框架的实现以云计算控制引擎为核心转换连接异构网络,并在NAT-PT与隧道技术协作下完成。框架建立的网络结构适用于IPv4虚拟机与IPv6虚拟机在过渡演进的前期、中期和后期之间的无缝迁移,并可向客户端跨IPv4/IPv6网络提供云计算服务。

Live migration transition framework of mobile IPv4/IPv6 virtual machine

In order to fully use IPv4/IPv6 heterogeneous network resources and provide resource requirement for cloud computation platform, the authors designed an IPv4/IPv6 virtual machine migration transition framework for cloud computation based on tunnel technology, prefix management, address pool management and mobile IP. The framework used the designed cloud computation control engine as a core to translate and link heterogeneous network, and needed Network Address Translation-Protocol Translation (NAT-PT) and tunnel technology collaboration. The framework was established for IPv4/IPv6 virtual machine seamless live migration in the early, middle, late period of IPv4 to IPv6 transition, and IPv4/IPv6 cloud computation service was provided for client. The framework could be applied to construct cloud computation platform in the IPv4/IPv6 transition period.
