FLOWPRI-SDN: A Framework for Bandwidth Management for Prioritary Data Flows Applied to a Smart City Scenario

Abstract

Applications have different requirements in terms of bandwidth and delay to deliver the expected quality of service. Furthermore, these requirements can change dynamically, as well as the importance of data traffic flows in the service context. Addressing this dynamism is one of the greatest challenges in the management of conventional networks. For this and other reasons, new paradigms such as software-defined networking have emerged. SDN decouples network control from forwarding, allowing development of new applications for dynamic programming of the forwarding devices in a centralized way. The FLOWPRI-SDN Framework is proposed in this work as an application built on top of the Ryu controller for priority resource reservation. Finally, the Framework is applied to a Smart City scenario, where it is shown that there are benefits in its use.
