Evaluación del rendimiento de un prototipo SDN (Software Defined Networking) bajo el protocolo OpenFlow utilizando herramientas Open Source en un entorno virtualizado

Abstract

The aim of this article is to evaluate the performance of a software-defined network prototype (SDN), the study is focused through the use of open-source tools for network management with SDN controllers (OpenDayLight, ONOS and Floodlight) and for environment emulation (Mininet). In addition to the use of metrics for performance analysis such as latency, connectivity, packet loss, message exchange, throughput, SDN controller availability and performance based on network services such as streaming, ftp transfer rate and web service. The main results show that network performance is related to SDN controller capabilities, and that each controller excels in different performance parameters, with OpenDayLight performing best in QoS measures, averaging 0.936 ms with a tendency to vary below or above 0.72 ms and 1.97% in packet loss.
