“…Google B4 [8] may be one of the few examples that have proven that SDN can be resilient at scale. A number of related efforts [355], [476], [477], [261], [478], [479], [480], [481], [361] have started to tackle the concerns around control plane split architectures. The distributed controller architectures surveyed in Section IV-D are examples of approaches towards resilient SDN controller platforms with different tradeoffs in terms of consistency, durability and scalability.…”

“…On a detailed discussion on whether the CAP theorem [482] applies to networks, Panda et al [477] argue that the tradeoffs in building consistent, available and partition-tolerant distributed databases (i.e., CAP theorem) are applicable to SDN. The CAP theorem demonstrates that it is impossible for datastore systems to simultaneously achieve strong consistency, availability and partition tolerance.…”

“…However, the proposed algorithm can also be applied for out-of-band control networks. In any case, we note that naive out-ofband control may actually provide lower resilience to failures [11]. The work in this paper can help prospective SDN operators mitigate their concerns about having a logically centralized control plane in their networks.…”

“…Isto porque, caso tal visão centralizada seja implementada por umúnico controlador, uma falha nesse elemento pode levarà indisponibilidade total da rede. O problema fundamental e os tradeoffs por trás da distribuição do controle em redes SDN podem ser modelados adaptando o teorema de CAP [Panda et al 2013]. 2 Embora tenha ficado claro desde a especificação inicial do OpenFlow que o controlador, apesar de logicamente centralizado, poderia ser implementado de forma distribuída, somente a partir da versão 1.2é que os mecanismos para esta distribuição começaram a ser especificados.…”
