Improving Energy Efficiency on SDN Control-Plane Using Multi-Core Controllers

Abstract: Software-defined networks have become more common in data centers. The programmability of these networks is a great feature that allows innovation to be deployed fast, following the increasing number of new applications. This growth comes with a cost of more processing power and energy consumption. Many researchers have tackled this issue using existing routing techniques to dynamically adjust the network forwarding plane to save energy. On the control-plane, researchers have found algorithms for positioning t… Show more

“…They run on a managing server (it could be a SDN server executing those algorithms as network apps) that also executes the needed machine learning tools. The consumption used by the server processor (Oliveira et al 2021) to implement our model did not exceed 7 W (normal consumption of a single AP). That is, it was negligible.…”

“…The main inconvenience of those techniques is that the usage of extra devices increases the cost and complexity of the energy savings mechanism. In contrast, we do not use extra devices; we implement our method with standard management software and machine learning software (Oliveira et al 2021).…”

“…The effectiveness of parallel methods in improving network performance has been the subject of several research efforts. With parallel implementation, researchers can apply more processor cores at lower frequencies to more network controllers, closing the performance gap in multi-controller scenarios, as done in the research referenced in [15]. Lowering the operating frequency of each core and implementing controllers in parallel results in greater energy efficiency.…”
