In a new era of technology world of software-defined networks is running faster nowadays. The Internet demands the growing popularity of computer networks. This traditional network system does not satisfy the recent computer needs. SDN includes so many other facilities like it is allowing operators of the network and while exploiting the network, users can remotely access and control network devices. In the comparison of this network is much better than any other controller. There are so many softwaredefined networks like POX, NOX, ONOS, Open Day light, etc. These controllers are for the NFV infrastructure of a data center. These controllers provide some policy and centralized management. Advantages of the software-defined network – programmability, virtualization of tasks, and management of the network in an easy way that provides SDN platform and on the other side POX controller based on a Python and open source OpenFlow SDN controller for faster development. To create a prototype of network applications formly it comes from pre-installed with the Mininet-virtual machine. POX controller can turn dumb OpenFlow devices into the hub, switch, load balancer, and firewall devices. In this paper performance metrics such as service Delay, utilized bandwidth, received packets, and bytes were measured and recorded using network monitoring tools like iperf to analyze the functionality of the POX controller as well as to evaluate the operating performance of the POX controller forSDN environment. The results of this research were the recommendation of using POX controllers for the development and prototyping of network control systems
