【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。
[Abstract]:In order to meet the requirement of consistent migration of virtual domains across data center policies in hybrid cloud environment, a virtual domain migration mechanism, IDVE, is proposed to migrate virtual networks between data centers using virtual encrypted tunnels through virtual quasi-domain consistency migration protocol between data centers. So that the topology and network configuration of virtual domain remain unchanged when the virtual domain is migrated. The proposed scheme satisfies the requirement of consistent migration of virtual domains across data centers, and enables network topology and configuration to be set up in advance at the time of virtual machine migration, thus greatly reducing the downtime of virtual machine migration. The test results show that the drop loss of virtual tunnel is about 25% and the downtime of virtual tunnel is only 0.81 s during migration, which can meet the needs of practical application.
