| Abstract(in English) | Virtual Machine(VM) migration is effective method for load balancing. Reduction of average time for migration mitigates physical server's load faster. Reduction of transmitted data for migration is well-known method for shortening migration time. Deduplication is one of the effective method. If there is identical data which is contained in multiple VMs, only one copy of it is transmitted to destination server when deduplication works. And the migration time also depends on the timing for migrating data constituting each VMs, especially when we exploit deduplication. Suitable data transmitted at early moment is one whose bitpattern appears in many VMs which is shrinked into one copy. But until the moment when all VM's data including unique one for each VM is transmitted, migration of the VM doesn't finish. This contradiction complicates the problem how to optimize order for migrating data to minimize the average migration time. Virtual Machine(VM) migration is effective method for load balancing. Reduction of average time for migration mitigates physical server's load faster. Reduction of transmitted data for migration is well-known method for shortening migration time. Deduplication is one of the effective method. If there is identical data which is contained in multiple VMs, only one copy of it is transmitted to destination server when deduplication works. And the migration time also depends on the timing for migrating data constituting each VMs, especially when we exploit deduplication. Suitable data transmitted at early moment is one whose bitpattern appears in many VMs which is shrinked into one copy. But until the moment when all VM's data including unique one for each VM is transmitted, migration of the VM doesn't finish. This contradiction complicates the problem how to optimize order for migrating data to minimize the average migration time. We propose the algorithm for calculating optimized order to minimize the average migration time per VM. We research duplicate bitpattern of VMs running on physical server to recognize how many identical bitpatterns appear and evaluate the performance of proposed algorithm by computer simulation using modeled VMs featuring the result of the research. |
