Provided are an optical line terminal, a distribution point unit, a system and a data stream scheduling method. The optical line terminal (OLT) in the present invention comprises: a receiving module, a scheduling module and a sending module, wherein the receiving module is used for receiving a data stream sent to a plurality of customer premises equipment (CPE) from a network side, and storing the data stream into a plurality of buffer queues corresponding to the CPE; the scheduling module is connected to the receiving module, and is used to schedule data streams in the plurality of buffer queues corresponding to the CPE in the same group to the same data stream queue according to grouping information about the CPE; and the sending module is used for sending a data stream in a data stream queue to a distribution point unit (DPU) through a data stream established with the DPU. The embodiments of the present invention reduce the complexity and power consumption of a DPU, the buffer requirements of the DPU, and the number of data stream connections between an OLT and the DPU. |
