Modeling and performance analysis of scheduling system for cloud service based on stochastic network calculus

In the background of cloud service is widely used, performance of the network has become more and more important, therefore the ability to guarantee the QoS of cloud networks is an important and essential part. To meet the demand for the QoS of cloud service network, we need an effective scheduling model to reach the user´s requirements, and a tool to calculate the theoretical bounds of QoS parameters. As a tool for network analysis which is still evolving, stochastic network calculus is the theory to analysis the stochastic network service systems. We propose an efficient scheduling method of multiple priorities and differentiated services to reach users´ expectations, and use stochastic network calculus to analyze the QoS parameters of cloud service network, it is proved that this scheduling method can meet the needs of different users of the network.
