Load balancing algorithm based virtual machine dynamic migration scheme for datacenter application with optical networks

This paper proposes a load balancing algorithm based virtual machine dynamic migration scheme for datacenter application with optical networks. The combination of the virtual machine dynamic migration scheme and the load balancing algorithm can help the virtual machines' migration with a dynamic adjustment on the basis of the current data center's situation in real-time. And in this way, it can reach the minimum average load among data center's occupation of service resource. Besides, the experiment results show that the time of migration process is very short, and users' service level agreement (SLA) can be met well.
