Network Performance-Aware Virtual Machine Migration in Data Centers

Virtual Machine (VM) consolidation and migration technology in data centers greatly improve the utilization of the server resource. While the previous work focuses on how to use VM migration to balance physical host utilization or optimize energy consumption, little attention has been given to network performance factors, such as link traffic load and inter-traffic between VMs in data centers. In this paper, the authors present MWLAN (Migration with Link and Node load consideration), a novel automatic data center VM migration system that can detect hotspots (e.g., network congestion and physical host over-loaded) and dynamically remap VMs to improve the network performance.
