Abstract: Resource allocation in data centers has always been a hot issue at home and abroad. In view of this, a package drift strategy is proposed in the framework of packet cluster. Firstly, this strategy degrades the mapping complexity between virtual machines and servers by using the hierarchical idea of packet cluster. According to the resource load on the cluster, FCM method is used to partition the cluster. Then, according to the maximum correlation algorithm, packets are selected to join the queue to be drifted, and the processing priority of the queue is set. Finally, a probability model is constructed to select the best target cluster for the drift package according to the drift cost and resource matching degree. Experiments of the packet drift strategy on CloudSim simulation platform show that the proposed scheme can effectively improve the service quality and resource utilization of data centers, and also has good performance in reducing energy consumption.
