Abstract


5G mobile technology will become the new revolution in the mobile communication market. The new networks will focus on significantly improving the quality of service. The basis for their construction will form SDN networks. Therefore, the work analyzed the advantages and disadvantages of two SDN implementing methods. It was developed mathematical method to assess their complex effectiveness, which consider QoS requirements of implementing service through special weights for scalability, performance and packet delay. There were simulations of Overlay networks by using softswitches to verify the adequacy of the proposed method. The results showed that the use of SDN networks more efficiently by using IP networks for large volumes of traffic and with a large number of network equipment. Also, there were compared the approaches to build SDN management level architecture. Based on the studies and modeling we suggested to use distributed controller architecture because of its higher level of reliability.
