摘要
摘要:大规模灾难事件可能对通信网基础设施造成严重的威胁和破坏。针对大规模灾难风险下虚拟网的生存性问题，该文提出一种多虚拟机快速协同撤离(MRCE)机制。该机制采用后复制迁移技术实现虚拟机的在线迁移，通过基础迁移带宽的分配和升级，对属于同一虚拟网的多个风险虚拟机进行快速协同撤离，以减少单个虚拟网的撤离完成时长，降低损毁风险。仿真结果表明，该机制能在不同考察周期内获得较好的虚拟网撤离完成率和平均撤离完成时长。

Abstract:Large-scale disaster events might critically threaten and damage the infrastructure of telecom networks. In view of the virtual network survivability issue under large-scale disaster risks, a Multi-virtual-machine Rapid Cooperative Evacuation (MRCE) mechanism is proposed. The proposed mechanism employs the post-copy technique for live migration of virtual machines. By means of the basic migration bandwidth assignment and upgradation, a rapid cooperative evacuation is conducted on multiple risk virtual machines belonging to a single virtual network, so as to shorten the evacuation time of that virtual network and reduce its damage risk. Simulation results show that the proposed mechanism can achieve better performance than its counterparts in terms of virtual network evacuation completion ratio and average evacuation completion time in different observation periods.
