Abstract [en]

 Passive optical networks are currently the major contributor to fixed optical networks energy consumption. Within PON, almost 65% of their energy consumption is due to the customer premises equipments (i.e., the ONUs).Standardisation authorities, industries and researchers are proposing several methods for decreasing ONU energy consumption. Cyclic sleep or fast sleep is one of the proposed methods that is based on cycles of sleep and waking periods. However, cyclic sleep, while decreasing ONU energy consumption, causes an increase in the delay experienced by the transmitted data. Based on the requested Quality of Service (QoS) such additional delay can be more or less detrimental for the carried service. Therefore, it is essential to optimally select when to sleep and for how long, based also on the services subscribed by the ONU.This presentation will outline a method for maximizing energy savings while providing services with delay guaranteed. The method exploits service-based variable sleep periods. Simulation results prove the method effectiveness with both Poisson and heavy-tailed traffic. The presentation will also provide an overview of the testbed implementation of the proposed approach
