Avaliação de desempenho de um controlador SDN implementado como uma VNF
Resumo
No presente trabalho, realizamos experimentos com um controlador SDN implementado como uma função de rede virtual nos hypervisores de código aberto KVM e XEN e comparamos os parâmetros de desempenho mais críticos em relação a um cenário nativo com o propósito de mensurar a degradação de desempenho causada pela virtualização. Utilizamos Cbench para emular redes SDN e avaliar o desempenho e a latência do controlador Floodlight. Descobrimos que a virtualização do controlador no ambiente KVM resultou na degradação do processamento de fluxos em 29%, apresentou um aumento do tempo de resposta de 22% e utilizou bem menos o processador em relação ao ambiente Xen, que apesar de ter sobrecarregado a CPU em 25%, foi capaz de atingir o melhor desempenho, tempo de resposta e a menor utilização de memória RAM.
