Evaluación de la calidad de servicio en redes móviles 5G implementando segmentación de recursos basada en arquitectura SDN

Abstract

In this paper is presented the emulation in software Mininet of different software defined network (SDN) environments with the open source controller Floodlight, based on the protocol OpenFlow, which makes decisions according to user profiles predetermined by the network administrator, on particular topologies. With the intention of controlling bandwidth resources that allow to guarantee values of latency and reliability, according to the type of service in a 5G Slicing network. In this way, it was possible to demonstrate the versatility and scalability of the Floodlight controller, which reduced the lost ratio by 10% in a congested network and guaranteed delays of less than 700 ms in applications such as VoIP and Video Streaming sharing a limited channel with 5 Mbps as the maximum bit rate.
