摘　　要：针对混合云环境下虚拟域跨数据中心策略一致性迁移的需求,提出虚拟域迁移机制IDVE,通过数据中心间虚拟域一致性迁移协议,在数据中心间利用虚拟加密隧道迁移虚拟网络,使得虚拟域的拓扑和网络配置在虚拟域迁移时保持不变。该方案满足了跨数据中心虚拟域一致性迁移需求,并能使网络拓扑和配置在虚拟机迁移时提前设置完毕,大大减小了虚拟机迁移停机时间。测试结果表明:迁移时虚拟隧道下降损耗约为25%,停机时间仅为0.81 s,满足实际应用需要。In response to the demand for the consistency migration policy of virtual domain among hybrid clouds,a mechanism of virtual domain migration called IDVE was proposed. Via the protocol of consistency migration of virtual domain between the data centers and using encrypted virtual tunnel to migrate virtual network,the proposed mechanism makes the topology of virtual domains and network configurations unchanged. This scheme meets the needs of consistency migration among data centers, and lets the topology of networks and configurations set up in advance when virtual machines begin to migrate,which greatly reduces downtime of migration. The results of experiments showed that when migrating,virtual tunnel decreases up to 25%,and downtime is only 0. 81 seconds,meeting the actual needs.
