A tecnologia SDN em redes móveis 5G

Abstract

The new technologies that will boost the development of smart cities, autonomous cars and the internet of things will significantly increase the data rates of networks. A diverse range of new devices will emerge and with them the need to attend a series of requirements, in addition to the demands for extremely low latency and extremely high throughput. 5G joins this scenario as a solution to this new era that requires a high number of connection at the same time. In this first moment, the new network is being implemented using the core infrastructure of the existing 4G network, however, a new core is being standardized and will use SDN and NFV technologies, seeking to bring simplicity and flexibility, transforming the current model into a totally new paradigm with great benefits. This work aims to understand, through a technical study, the application of SDN in this new architecture developed for 5G, detailing its operation and highlighting advantages and disadvantages, emphasizing that it will bring dynamism for the network services and it is presented as a key technology for achieving several challenges required in this new generation of mobile networks.
