In this paper, the control algorithm which can resolve the unfairness in network performance of the virtual machine arised from the CPU scheduling in cloud datacenter has been proposed. We first describe the evaluation and analysis results of the network unfairness phenomenon of virtual machine through the heterogeneous cloud datacenter testbed and we propose the control algorithm which can guarantee the fairness of the network performance based on the PID control scheme. Through the implementation and evaluation results, we verify the performance of the proposed algorithm.
