Open Flow, an essential technology in Network functions virtualization (NFV) implementation, enables software-dened networking (SDN) to develop from a simple concept and divides traditional switch into two parts: a data plane and a control plane. Because software-dened rules are used to control traffic, the concept of NFV was developed. Numerous virtualization studies on NFV have investigated conventional networking hardware, such as firewalls, load-balancers, routers, and managed switches. In this paper, we describe virtualizing a basic switch and implementing a network traffic monitor system. The virtualized switch is used to replace a conventional managed switch and monitor traffic without the need for port mirroring hardware. In addition, Open Flow is incorporated to manage networking. Cloud computing is increasingly prevalent, and technology is advancing. The proposed system in this paper can be implemented in any networking environment.
