Abstract:
1. A method for improving efficiency in a passive optical network (PON) implemented by a optical network unit (ONU) connected to an optical line terminal (OLT) over an optical line, the ONU connected with an aggregating ONU (AG-ONU) in the PON through an alternate connection separate from the PON, the ONU improving cost and energy efficiency of the PON by entering a sleep mode that disables communication with the OLT to reduce energy consumption when the ONU is idle, the ONU to restart communication with the OLT upon receipt of data traffic by performing the method comprising the steps of: checking whether the received data traffic has a high priority and low bandwidth requirement ( checking whether the alternate connection can service the received data traffic having the high priority and low bandwidth requirement ( processing the received data traffic having the high priority and low data bandwidth requirement that can be serviced by the alternate connection by transmitting the received data traffic to the AG-ONU over the alternate connection to be forwarded to the OLT over the PON ( processing the received data traffic having a low priority or high data bandwidth requirement by (
