Abstract: SDN is the developing paradigm, breaking vertical integration into existing networks so that network may be programmed flexibly via (logical) centralised control of the network. SDN is able to adjust its fly-based network settings dependent on its operational environment. The technology for software defined networking (SDN) removes tight link amid control & data planes, which makes monitoring of network resources, safety & economies a reality in traditional network design. Machine learnig (ML), paired by SDN architescture, will have a significant probable in fields e.g. The main means of upgrading of the artificial intelligence is through network management, route scheduling, traffic planning, fault diagnostics & safety (AI).In this paper, we discuss concepts, advantages and inconveniences of up-to-date energy efficiency SDN methods. We are also able to compare current techniques, debate open topics and a guidance for future investigations in a short time. We also conduct a review of the various energy efficiency and network-security techniques adopted through SDN deployment. We examine the key active research, challenge and trend in that sector in order to forecast the future evolution of these new paradigms. This article enables readers to have a more comprehensive grasp of SDN architecture, various security threats, and EE.Keywords: Network definite software, virtualization of network, energy efficiency, security of SDN, OpenFlow network, administration of networks.
