Faced with increasing energy prices, nancial crisis and en- vironmental problems, the sector of information and com- munications technologies initiates the third industrial rev- olution. This revolution aims to intelligently allocate and distribute energy. The study, development and implemen- tation of intelligent energy managers for computer networks is called green networking. The proposed paper aims to de- velop and test an energy-aware solution. EAAC-MQ, an Energy-Aware Admission Control for wired networks, has been created and tested with NS-2 (Network Simulator). This solution adapts its behavior to tra c classes (Mul- tiple Queues, MQ) to meet the divers needs in network ressources. It reduces energy consumption, and therefore operating costs, about 20%, despite of reducing throughput and increasing delay.
