Flexible data center backup in WDM networks based on virtual machine migration and elastic bandwidth allocation
Cunqian Yu, Lei Guo, Weigang Hou, Yue Zong · 2014
Since data center carries plentiful applications, its failure results in huge data loss. In order to mitigate service's paralysis caused by data center failure, we propose a flexible data center backup framework through highly efficient virtual machine migration and grading along with elastic bandwidth allocation.
