Secure Voice IP implemented in Software Defined Networks

Abstract:

Talking about software-defined networks is a paradigm, they are more agile, scalable and dynamic, for a better increase in programming and automation. One of its advantages is the reduction of operating costs, improvement in network performance, with an open architecture allowing different providers to migrate to these networks. This article is focused on the implementation of a software-defined network that allows to provide secure Voice IP service, analyze and identify which are the controllers and protocols used in the networks and select the one that best suits the study. Through a descriptive-documentary study, the design and implementation of a network is carried out, in a physical environment, using Routerboards and IP phones, allowing their interconnectivity. Metrics such as: Latency, performance, bandwidth are performed, and the security presented by the network is evaluated through Voice IP technology. As a result, the test conducted in a controlled environment, determined that the network had less loss and delay in terms of the time interval of the packets. It is concluded that a good choice of the OpenDayLight controller and the OpenFlow protocol will be of great help for a stable connection with the equipment.
