Uma abordagem multiobjetivo para definição de rotas em Redes Definidas por Software (SDN)

The popularization of cloud services and applications has dramatically changed Internet traffic profiles. Such changes have instigated the evolution of the SDN (Software Defined Networks) paradigm, where the data plans and control of the switches are separated, allowing a centralized view of the control and a series of new applications. Two important problems in traffic engineering are load balancing and energy efficiency in the use of network resources. In this scenario, the present work proposes a multiobjective optimization model for routing. Performed tests indicated improvements in performance and energy efficiency, according to the preferences.
