Abstract(s)
Perante a estática e praticamente imutável estrutura das arquiteturas de redes IP os administradores
procuram soluções para a escalabilidade crescente do número de aplicações que emergem na área do
software de administração de rede a que se chamou Software Defined Networking (SDN). Os principais
objetivos desta promissora arquitetura são simplificar as operações da rede, reduzir custos e acelerar a
entrega de serviços, dando aos administradores da rede a opção de alterar as redes para uma arquitetura
aberta e com um novo tipo de interfaces. A SDN suporta a natureza dinâmica das funções de rede e
aplicações. Hardware, software e gestão da estrutura convergem para uma solução de rede capaz de
atender à enorme procura incessante de tráfego no futuro próximo por novos paradigmas de TI:
mobilidade, Interne of Everything (IOE), computação em nuvem e “Big Data”.
A SDN requer a utilização de software em código aberto, para alavancar o seu crescimento e para
tirar vantagem das diferentes topologias e modelos de arquiteturas de redes físicas, projetadas para
diferentes fins. Aborda-se ainda a utilização da arquitetura OpenFlow, protocolo de trabalho do nível
inferior do framework SDN, bem como a sua utilização e evolução pelas grandes organizações
tecnológicas do ramo de negócio tendo em vista a sua utilização em grande escala nos centros de dados
e sistemas de computação em nuvem.
Porque a maior parte dos clientes confia num único fornecedor e solução, ou pelo menos num
fornecedor dominante, podemos concluir que o foco principal para os administradores de rede será
projetar e implementar uma estratégia de SDN. Isto levá-los-á a escolher uma gama de soluções
desenvolvidas por uma plataforma em código aberto. Se tivermos em conta a forte evolução dos últimos
dois anos e o esforço realizado pelas empresas do setor nesta arquitetura tecnológica, podemos afirmar
que esta arquitetura de rede tomará conta da gestão e administração das redes num futuro próximo.
Software Defined Networking (SDN) is an emerging topic and discussed as one of the most promising network architecture that could simplify network operations, reduce costs and accelerate services delivery. Facing the static and virtually unchanging structure of the traditional IP network architecture, administrators seek solutions to the growing scale of the number of network administration applications. SDN gives network customers a choice to change their networks for open architecture and new type of interfaces. SDN supports dynamic nature of network functions and applications while lowering costs. Hardware, software, and management converge to a networking capable of meeting the huge traffic delivery demand in the near future by new paradigms of IT, mobility, Internet of Everything, cloud and Big Data. SDN requires the use of open source software, to leverage its growth and to take advantage of different topologies and models of physical network architectures, designed for different purposes. This work also addresses the using of OpenFlow architecture, level of work protocol lower SDN framework, as well as their use and development by large technology organizations and business branch with a view to its use in large-scale datacenter and cloud computing systems. Because most customers rely on a single supplier and solution, or at least a dominant supplier, we can conclude that the main focus for network administrators will be designing and implement an SDN strategy. This will lead them to choose a full range of solutions developed by an open source platform. Taking into account the strong growth the past two years and the efforts made by companies in the industry in this technology architecture, we can say that this network architecture will take care of the management and administration of networks in the near future.
