It is a new paradigm to hear about SDNs (Software Defined Networks), they are more agile, scalable and dynamic, for a better increase of programming and automation. It presents some advantages one of them is the reduction of operational costs, improvement in the performance of the network, its architecture is open what allows a better variety of suppliers for the companies that want to migrate to these networks. This project is focused on the implementation of a software defined network (SDN) to provide secure VoIP service. That is why one of its objectives is to analyze and identify which are the controllers and protocols used in the SDNs and to select the most appropriate for the research project. It is proposed to carry out the design and implementation of a network, in a physical environment. The equipment that will be used in the SDN network, consists of a routerboard and IP phones, which will allow the interconnectivity of them and accessibility to the Internet. In this test scenario, metrics are proposed to measure latency, performance, bandwidth, among others. It is also intended to evaluate the security, which presents the SDN network through VoIP technology, for this purpose security attacks will be carried out to check its vulnerability. Finally, the results obtained will be discussed and the conclusions and recommendations regarding the proposed objectives will be presented.
