Abstract:

Software-Defined Networking(SDN) is a growing network technology that has brought significant benefits to a wide range of disciplines,from science to technology to various fields. This structure can be used in network-based environments, data centers and various research sites. OpenFlowis one of the most widely used protocols for interaction between a controller and a switch in a Software-Defined Networking. Understanding the performance and limitations of the network defined by open source software, including bottlenecks and security vulnerabilities due to the centralized network structure, areimportant prerequisitesfor the efficientdeployment ofthesesystems. Thesepoints of view led researchers to examine various related mathematical models to addresstheseissues. Queueing theory provides the most important and accurate model for evaluating the performance of the SDN networks affected by these restrictions, which has attracted the attention of researchers recently. Regarding to extensive mathematical modeling, this theory has also been used to improve network efficiency. Researchers have used this theory to investigate operational power and improve time consumption and control of data planes due to the nature of classification and storage of packets in SDN buffers. These methods overcomecontroller performance bottlenecks and increase SDN control capacity, especially forlarge distributed networks. In this paper, we examine the queueing models for different applications in different layers of SDN, in which researchers use these methods to monitor network loads,evaluateand predict performance changes due to diversityin network traffic. We introduce and review a collection of articles that explore, different applications of Queueing theory in SDNnetworks. In addition, in order to increase the efficiency of this research, detailed comparisons are performed in terms of structure, mathematical models and the final simulation results.
