| Zusammenfassung: | Device and method for scheduling traffic exchange in a passive optical network, PON, to reduce energy consumption. The method includes a step of instructing an optical network terminal, ONU, and an optical line terminal, OLT, in the PON to maximize an overlap between upstream and downstream communications by exchanging a predetermined future time (t2) at which to start the upstream and downstream communications; a step of sending to the ONU a predetermined time interval (G) during which the ONU need to have a transmitter and a receiver on; and a step of adding a flag (MPSMP) to a control message sent from the OLT to the ONU that is indicative of whether further messages are to be received from the OLT or not. |
