    摘要： A method and apparatus of detecting a rogue optical network unit (ONU) is provided. An optical line terminal (OLT) detects an abnormal upstream transmission to determine a plurality of rogue ONU candidates, and transmits a sleep allow message instructing a transition to a sleep mode to each of the plurality of rogue ONU candidates. The OLT detects the rogue ONU among the plurality of rogue ONU candidates based on upstream transmissions from the plurality of rogue ONU candidates in the sleep mode. Since the detection of the rogue ONU is performed in the sleep mode, the remaining ONUs can transition from the sleep mode to the normal mode after the detection of the rogue ONU is completed, thereby making it possible to rapidly resume upstream communication.

    摘要： Provided is an apparatus for filtering a multicast port identifier, the apparatus including: a processor to receive an Internet Group Management Protocol (IGMP) message from a switching unit, to verify a traffic reception request received from a subscriber terminal based on the IGMP message, and to store a value in a filtering register based on the traffic reception request; and an Optical Network Unit (ONU) Media Access Control (MAC) manager to filter a packet to be forwarded to the subscriber terminal, using a port identifier for traffic forwarding and reception with the subscriber terminal, and using the value of the filtering register indicating an existence of traffic to be forwarded to the subscriber terminal.

    摘要： Disclosed is a low power optical network terminal (ONT) and a method of operating the low power ONT. The low power ONT may include a network media access control (MAC) processing unit to transmit and receive traffic to and from an optical line terminal (OLT), a switching unit to receive the traffic transmitted from the network MAC processing unit and transmit the traffic to a subscriber terminal and to receive the traffic from the subscriber terminal and transmit the traffic to the OLT, and a control unit to control traffic transmission from the network MAC processing unit when a power mode is a low power mode.
