随着虚拟化技术的迅速普及，实时迁移提供了在物理主机之间不中断地迁移正在运行的虚拟机（VM）的能力。特别是，全球实时迁移（GLM）能够跨地理分布的广域网（wan）迁移VM，这是迈向云间环境发展的重要一步。然而，与普通的实时迁移相比，GLM在网络配置方面有点复杂。我们已经提出了GLM方法，该方法通过多个接口实现IP迁移支持架构，以实现由不同IP网段组成的分布式站点之间的实时迁移。但是，对于Internet上虚拟机迁移的平滑切换管理，没有足够的考虑。在本文中，我们提出了一个GLM的移动性管理系统，并将其集成到我们发达的全国性虚拟化基础设施中。该系统支持虚拟机无缝切换，无需修改管理程序，同时保持迁移站点的网络配置。性能评估显示了采用GLM的管理系统在距离超过600公里的多个站点之间的处理开销。因此，我们确认，如果所提议的系统被实现，所提议的系统可以为广泛分布的环境中的VM提供平滑的切换。
With rapid spread of virtualization technologies, Live migration which provides the ability to migrate a running virtual machine (VM) among physical hosts without interruption. Especially, Global Live Migration (GLM) which enables to migrate VM across the geographically-distributed Wide Area Networks (WANs) is an essential step towards development of the inter-cloud environment. However, GLM gets a bit complicated for network configuration compared with ordinary live migration. We have already proposed the GLM method which implements IP mobility support architecture with multiple interfaces to enable live migration among distributed sites consisting of different IP network segments. However, there is no sufficient consideration about the management of smooth handoff for the VM migration on the Internet. In this paper, we propose a mobility management system for GLM, and integrate into our developed nation-wide virtualization infrastructure. The proposed system enables VMs seamless handoff without any modification of the hypervisor while keeping network configuration of the migrating site. Performance evaluation shows the processing overhead of the proposed management system with GLM among multiple sites which are more than 600 km distant. As a result, we confirm that the proposed system provides smooth handoff for the VM on the widely-distributed environment if the proposed system is implemented.
