| Summary: | Considering the survivability of virtual networks in a network virtualization environment，a virtual network embedding approach was proposed to survive multiple node failures.It de backups proportionally in the substrate network and constructed a candidate set for each substrate node beforehand.To increase the long term business profit，it chosen the failover targets in the candidate set and dynamically allocates backups to recover the affected virtual networks after substrate node failures.The validity of this method is assessed by simulation experiments in terms of applicability，stability and performance under a multiple node failures model. |
