Recently, Technology and the web had a fast evo-lution. Assuming this, Software-Defined Networking (SDN) has been conceived to offer tenants improved network management, allowing modern services in business features. Additionally, SDNs allow the creation of many different and independent virtual networks, called virtual SDNs (vSDNs). However, some issues are present, e.g., resilience (i.e., recovering after a determined equipment stop working) and power consumption optimization of topologies with idle devices. This paper proposes an approach based on vSDN that optimizes power consumption by switching off idle equipment. This approach assumes multiple tenants and creates vSDNs according to the considered network topology metrics (e.g., power usage effectiveness (PUE), delay, power con-sumption, packet loss, availability, and reliability). In addition, the Network Model Flow (NMF) is proposed to represent the data flow on the network. To optimize power consumption, we proposed an approach that put the idle devices into the sleep mode. In the experiments, the proposed strategy reduced the power consumption upper than 50%.
