Abstract: A method of registering an optical network unit (ONU) in an optical line terminal (OLT). The OLT determines a lane to be used by the ONU based on a transmission rate supported by the ONU, combines or distributes data of a dataflow based on a rate of the lane by comparing the rate of the lane to a rate of the dataflow of a media access control (MAC) client interface, and, when the OLT and the ONU are connected through multiple lanes, transmits and receives data between the OLT and the ONU through channel bonding for more effective use of a network.

Abstract: Provided are an Optical Network Unit (ONU) for low latency packet transmission in a Time Division Multiplexing-Passive Optical Network (TDM-PON), a method of operating the ONU, and an apparatus for controlling the ONU. The method includes: receiving, from a base station, first bandwidth allocation information regarding a bandwidth allocated by the base station to a terminal for uplink packet transmission; and transmitting a bandwidth allocation request, which is based on the received first bandwidth allocation information, to an Optical Line Terminal (OLT) before completing packet reception from the base station.

Abstract: Provided are a power management method and apparatus of an ONU supporting a slicing function. A power management method performed by a power management apparatus of an ONU supporting a slicing function includes receiving a first message for discovering a power management attribute of an ONU including at least one slice from an optical line terminal (OLT), transmitting a second message including the power management attribute of the ONU to the OLT in response to the first message received, receiving a third message for setting up a power management parameter for each slice included in the ONU from the OLT, setting up the power management parameter for each slice included in the ONU based on the third message received, and transmitting a fourth message including a set up result of the power management parameter for each slice included in the ONU to the OLT.

Abstract: A method and apparatus for allocating a bandwidth based on machine learning in a passive optical network, the method including generating an inference model to predict a consumed bandwidth required for transmission by learning unstructured data of a PON including an OLT and traffic data corresponding to state information of the PON collected from the PON, predicting a consumed bandwidth with respect to a queue corresponding to a class requiring a low-latency service among classes of ONUS connected to the OLT based on the generated inference model, performing a VBA with respect to the queue corresponding to the class requiring the low-latency service based on the predicted consumed bandwidth, and performing a DBA with respect to a queue corresponding to a class not requiring the low-latency service using a transmission bandwidth which remains after the VBA is performed.

Abstract: Disclosed is a slice connection method of an optical access network and an optical access network system for slice connection. A slice connection method performed by an optical network unit (ONU) of an optical access network system may include determining a service type of a host device transmitting a service connection request, determining a slice based on the service type, sending a request for connection to the slice to an optical line terminal (OLT), and relaying data transmission and reception between the OLT and the host device when a slice connection response corresponding to the request is received from the OLT.

Abstract: A bandwidth allocation apparatus and method for providing a low-latency service in an optical network that may guarantee low-latency requirements and improve a network utilization rate by allocating a static bandwidth to an ONU requiring low latency within an allocable bandwidth and by allocating a dynamic bandwidth to an ONU not requiring the low latency within a remaining bandwidth.

Abstract: An optical line terminal (OLT) accumulates and stores a user frame for each physical layer identifier (PLID) to efficiently use a plurality of lanes used for downstream transmission from the OLT to an optical network unit (ONU). The OLT envelopes payloads that are accumulatively stored for the respective PLIDs based on a transmission rate supported by a corresponding ONU, combines an envelope header based on an envelope payload unit, and transmits an envelope frame. The OLT selects an available lane from among a plurality of lanes and may transmit the envelope frame through the selected lane.
