Quality of Service Control in Software-Defined 5G Networks

With the evolution of communication technologies, new applications have emerged aiming to improve the processes of information exchange and innovation, at the forefront of this evolution is the fifth generation of mobile networks (5G), which should provide the infrastructure for these new applications that have high capacity, reliability, energy efficiency and latency requirements. In this context, there are a number of changes that must be made to the network infrastructure, including Core Network (CN) and Radio AccessNetwork (RAN) to support these new applications. In this work we demonstrate the implementation of Quality of Service (QoS) control through the Software Defined Network (SDN) paradigm in an abstract (CN) infrastructure, with the objective of investigating the benefits of using SDN for new scenarios and challenges for 5G network. Experiments carried out with the Ryu SDN controller, demonstrated that the application of QoS through the SDN can bring benefits to the performance of these new applications.
