Abstract :
We propose a new dynamic bandwidth allocation algorithm for energy efficiency in next generation optical access (NGOA) networks, and evaluate the power savings possible at the optical network unit (ONU) by applying sleep and doze modes. Sleep mode is found to be most effective for NGOA systems with burst mode traffic transmission and reception.
