cTMvSDN: improving resource management using combination of Markov-process and TDMA in software-defined networking

Network simulation and capabilities in the form of a logical network has increased the development of virtual networks rapidly. It is one of the best ways to increase productivity and optimize hardware equipment. Network-Virtualization plays a very important role in the development of networks as the size of the networks increases vastly. This paper examines one of the most important issues in network virtualization to provide an efficient dynamic resources infrastructure management on Software-Based Networks. The proposed method (cTMvSDN) improves resource management based on combination of Markov-Process and Time Division Multiple Access (TDMA) protocol. A customized module to the controller only initializes the mapping when there are sufficient available resources. In order to optimize the response time and SDN Quality of service, the Markov-Pattern and TDMA slicing model are used to predict the next time gaps. Successfully mapped packets will be sent in TDMA slots. Simulation results performed with NS2 and Mininet simulator showed improvement in metrics such as delay and costs in comparison with relevant studies in the literature.
