Originální abstrakt

Network virtualization enables Internet service providers to flexibly provision heterogeneous virtual networks (VNs) over shared substrate networks (SNs). As more and more applications are carried by VNs, the survivability of VNs becomes a critical challenge under large-scale disaster risks. In this paper, we propose a synchronous evacuation strategy for VNs with dual virtual machines (VMs) inside a disaster risk zone (DRZ), which suffer higher risks than the VNs with single VM inside the DRZ. The evacuation strategy exploits post-copy technique to sustain the online service alive and enhances synchronous VM migrations to shorten the dual-VM evacuation time. Numerical results show that the proposed strategy can achieve satisfactory performances in terms of average and total evacuation times of dual-VMs.
