—Considering the increasing importance of carbon free networking solutions, several energy-efficient networking systems have been proposed and evaluated in literature. One significant challenge is how to encompass actions targeting energy savings and possible corresponding degradations in network QoS (Quality of Service). This paper presents an(More)
—Energy efficiency features are being integrated in network protocols and management systems. Simulations can provide input on how a particular algorithm would perform in different network conditions. However, building an environment that is able to comprehensively account for interactions between different network functions is difficult. A combination of(More)
—A significant number of green, energy-saving network protocols have been invented in recent years in response to demand for reducing the amount of energy consumed by network infrastructure. In this paper, we report on the difficulties we encountered when building an SDN environment that could emulate energy saving protocols operating at different layers of(More)
—Energy efficiency features are being integrated in network protocols and management systems in order to make the infrastructure more sustainable and, at the same time, address the growing users' demand. Many of such features affect the network in different ways, thus yielding trade-offs. They can affect the reliability and availability of the network when(More)
The identification of redundant computation is in general undecidable and prevents the obtainment of an ideal case as reference to the measurement of the remaining unexploited potential for redundancy removal and to the evaluation of code optimization effectiveness. This paper presents a methodology for optimization effectiveness analysis by observing the(More)
