Garantia de QoS no núcleo da rede móvel celular de quinta geração utilizando redes definidas por software

Abstract

With the evolution of communication technologies, new applications have emerged with the aim of improving 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 the core of the network and the radio access network to support these new applications. In this work we demonstrate the implementation of the Quality of Service control through the Software Defined Network paradigm in an abstract 5G network core infrastructure, with the objective of investigating the benefits of using the Software Defined Network in new scenarios and challenges for networks 5G. Experiments performed with the Ryu SDN controller, demonstrated that the application of quality of service rules through this paradigm can bring benefits to the performance of these new applications.
