A Virtual Machine Server Aggregation Algorithm Based on Hierarchical Clustering

Combining virtual machine technology and network computing technology will be able to effectively aggregate the widely distributed heterogeneous and autonomous resources in the Internet. This paper proposes a virtual machine server aggregation algorithm, called DVSA, based on hierarchical clustering method for virtual computing environment. According to network latencies, the algorithm clusters virtual machine servers into groups. If servers in the same group are scheduled, the latencies between virtual machines which host on these servers will be small, and the performance and stability of the distributed execution environment could be improved.
