云服务的激增使虚拟化技术变得更加重要。虚拟化的一个重要特性是实时虚拟机（VM）迁移。评估实时VM迁移机制的两个主要指标是总迁移时间和停机时间。现有的大多数关于实时VM迁移的文献都集中在设计迁移机制以缩短这两个指标或在它们之间进行权衡。它们中很少有可以应用于具有延迟要求的应用程序，例如需要在特定时间内完成的VM备份过程。这将对用户体验产生负面影响，并降低云服务提供商的利润。此外，广泛使用的预复制机制所需的频繁变化的带宽是难以由当前的网络技术提供的。在这项工作中，我们从理论上分析了需要多少带宽来保证一个活的VM迁移的总迁移时间和停机时间，然后提出了一种新的传输控制机制，以保证计算的带宽。实验结果表明，基于互逆模型的带宽保证了迁移总时间和停机时间的期望值，而传输控制机制保证了实时迁移流在存在后台流的情况下也能获得期望的带宽.
The proliferation of cloud services makes virtualization technology more important. One important feature of virtualization is live Virtual Machine (VM) migration. Two main metrics of evaluating a live VM migration mechanism are total migration time and downtime. Most existing literature on live VM migration focus on designing migration mechanisms to shorten the two metrics or making a tradeoff between them. Few of them can be applied to applications with delay requirements, such as a VM backup process that needs to be done in a specific time. This will negatively impact the user experiences and reduce the profit of cloud service providers. Besides, the frequently varied bandwidth required by the widely used pre-copy mechanism is difficult to be provided by current network technologies. In this work, we theoretically analyze how much bandwidth is required to guarantee the total migration time and downtime of a live VM migration, and then propose a novel transport control mechanism to guarantee the computed bandwidth. The experimental results demonstrate that the bandwidth obtained from the proposed reciprocal-based model guarantees the expected total migration time and downtime, and the proposed transport control mechanism ensures that the live VM migration flow obtains the expected bandwidth even if there are background flows.
