State of the art of existing standards for the evaluation of network performance and energy consumption

The expansion of the telecommunication market to a wider number of customers, along with the increasing of services being offered, has brought the CO₂ emissions to a dangerous level. Concern is due both to the impact on the environment and to the high costs caused by such energy consumptions. For these reasons, the scientific community is producing many researches to introduce power management capabilities in commercial network devices. Since reducing power consumption has the drawback of performance degradation, some benchmarking methodologies have been proposed to evaluate the trade-off between power consumption and network performance. This paper is devoted to critically analyse and compare the existing methodologies, in order to evaluate their effectiveness and possible enhancements.
