“…ONUs enter sleep mode of low power consumption under light traffic and periodically wake up. When ONUs wake up, the OLT helps ONUs to check whether it should remain asleep [ 17 , 18 ]. Further, to guarantee the quality of service (QoS) of high priority applications, a prequitting method is proposed to cooperate with sleep mechanism [ 11 , 19 ].…”

Energy consumption in optical access networks costs carriers substantial operational expense (OPEX) every year and is one of contributing factors for the global warming. To reduce energy consumption in the 10-gigabit Ethernet passive optical network (10G-EPON), a hybrid intracycle and cyclic sleep mechanism is proposed in this paper. Under heavy traffic load, optical network units (ONUs) can utilize short idle slots within each scheduling cycle to enter intracycle sleep without postponing data transmission. In this way, energy conservation is achieved even under heavy traffic load with quality of service (QoS) guarantee. Under light traffic load, ONUs perform long cyclic sleep for several scheduling cycles. The adoption of cyclic sleep instead of intracycle sleep under light traffic load can reduce unnecessary frequent transitions between sleep and full active work caused by using intracycle sleep. Further, the Markov chain of the proposed mechanism is established. The performances of the proposed mechanism and existing approaches are analyzed quantitatively based on the chain. For the proposed mechanism, power saving ability with QoS guarantee even under heavy traffic and better power saving performance than existing approaches are verified by the quantitative analysis. Moreover, simulations validate the above conclusions based on the chain.

“…While many studies dealt with the issue of energy efficiency in Passive Optical Networks (PONs) by means of mathematical analysis or simulations [1,2], only few of them target experimental evaluation. For example, in [3], a partial implementation of an Optical Network Unit (ONU) featuring sleep mode is presented together with a testbed that considers only downstream transmission.…”

“…So far in literature, very few attempts have been made in designing bandwidth allocation algorithms based on upstream traffic. Existing work mostly considers only the downstream traffic [5], [6]. Further the ONUs in these algorithms transmit whenever they have upstream traffic present in their queues which can cause packet collisions and packet loss in the network.…”

We previously proposed an energy-efficient Just-In-Time based dynamic bandwidth allocation algorithm for the 10 Gbps Ethernet Passive Optical Network. The algorithm exploits the capability of the Vertical-Cavity Surface-Emitting Optical Laser based Optical Network Units to operate in sleep or doze mode during its idle time. The algorithm takes into account the upstream traffic demand at the Optical Network Units in determining the bandwidth allocated to each Optical Network Unit during each cycle, thus eliminating possible collisions in the network. In this work we evaluate the performance of the Vertical-Cavity Surface-Emitting Laser and the Distributed Feedback Laser based Optical Network Units under the proposed algorithm. The simulation results indicate that the Vertical-Cavity Surface-Emitting Laser based Optical Network Unit outperforms the DFB ONU in terms of the energy efficiency using the proposed algorithm.
