Introduction− The traditional networks mostly implement devices where the control plane is distributed and mixed with the data plane; this fact does not allow a fast evolution to-wards a process that contributes to improving the transport of services. Otherwise, Software Defined Networking is a set of transport services that optimize the use of resources as these have a centralized network structure.Objective− To determine the aspects that enable the soft-ware-defined networking to provide quality of service features in data networks.Methodology−This study is performed through network simulation over the same base network and under the same working conditions by carrying out measurements of the pack-et forwarding response time and management of the trans-ported bandwidth. This study includes the demonstration of the multimedia content transport over a network architecture defining priorities to the links.Results−The outcomes show how the Software Defined Networking achieves better management of data transmis-sion through the base network. In the same way, the previous outcomes are reinforced with those obtained in the quality of service test performed on the streaming of a multimedia flow.Conclusions−Due to the centralized control of Software Defined Networking, forwarding functions with the quality of service features are enabled in data networks based on layer-2 devices.
