A demonstration of energy efficiency capabilities orchestration in networks Various energy efficiency network capabilities have been proposed in recent years in response to the demand of reducing the amount of energy consumed by the network infrastructure. In this regard, we demonstrate SOS, a method able to orchestrate different energy efficiency capabilities considering the possible combinations and conflicts among them, as well as the best option for a given bandwidth utilization and network characteristics, such as topology and power profiles of devices. The method was tested on GreenSDN, a testbed based on the Mininet environment and the POX controller, which emulates the effects of different energy efficiency capabilities. During the demonstration, we will show the energy efficiency achieved by the orchestration method, highlighting the additional savings due to capabilities orchestration, and, at the same time, considering performance constraints and different policies.
