Rede SDN-OpenFlow para o Caso de um ISP: Desafios e Oportunidades

This article proposes an architecture for an ISP (Internet Service Provider) utilizing SDN-OpenFlow. With this, we attempt to create a network with less equipment processing and more traffic engineering potentiality than today’s one, and at the same time without the problems that might exist in networks implemented with OpenFlow, as controller overload, additional delays in flows creation and excessive controller network dependence.The following attributes have been taken into consideration in the design: network robustness requirements, routing speed response, jitter, delay, traffic engineering and equipment processing load.
