ABSTRACT: Networks are usually the critical resource in data center. Imbalance of applications and traffic
distributions in data center networks usually causes local hotspot and congestion. Recently, many network-aware
solutions have been proposed for network performance optimization. Some of them try to find an optimal
VM-to-host mapping offline, while the others rebalance network load in an online fashion by VM migration.
However, due to the high complexity ofVM
