  In this paper we discuss the implementation of an ONOS application that
leverages Energy-Efficient Ethernet links between a pair of switches and shares
incoming traffic among the link in the way that minimizes overall energy usage.
As the straightforward solution can result in excessive traffic delay, we
provide two alternative solutions to meet the demands of real time traffic
arriving to the link aggregate. Experimental results show that our final
application can keep low energy usage while meeting the demands of
time-sensitive traffic, as long as the latter does not represent an excessive
share of traffic demand.
