摘要： A bandwidth scheduling method. The method includes a bandwidth allocation apparatus receives a bandwidth request message sent by a message conversion apparatus, where the bandwidth request message includes a bandwidth requirement, and the bandwidth requirement is a bandwidth required by a user-side apparatus for completing transmission of a service. The bandwidth allocation apparatus calculates first bandwidth grant information and second bandwidth grant information based on the bandwidth requirement, where the first bandwidth grant information is information about a bandwidth that is allocated to the user-side device, and the second bandwidth grant information is information about a bandwidth that is allocated to a second access device. The bandwidth allocation apparatus sends the first bandwidth grant information to the user-side device, and the bandwidth allocation apparatus sends the second bandwidth grant information to the second access device by using a first access device.

摘要： The present invention relates to the field of network communications. An Optical Line Terminal (OLT) allocates a Pseudo Wire (PW) label of an access segment PW for a port, and establishes a corresponding relationship between the port information and the PW label; and carries the corresponding relationship between the port information and the PW label in a label management message, and sends the label management message to an Optical Network Unit (ONU) so that the ONU updates a forwarding table, in which the label management message adopts an access network management protocol. As a consequence, a problem of supporting Pseudo Wire Emulation Edge-to-Edge (PWE3) on a data plane of an access segment of an access network is solved under the conditions that device complexity of the ONU is not increased and a configuration of the ONU is slightly changed.

摘要： A method for configuring a forwarding table for user equipment, an apparatus, and a system, where an operator server receives a service access request of user equipment, establishes a correspondence for the user equipment, and sends the correspondence to an access node (AN) controller. The correspondence includes a media access control (MAC) address of the user equipment and an identifier of an operator to which the user equipment belongs. The AN controller generates a first forwarding table according to the correspondence, and sends the first forwarding table to an AN. The AN forwards, using the first forwarding table, service data of the user equipment to the operator to which the user equipment belongs.

摘要： A method for allocating uplink and downlink bandwidth, includes: receiving, by a primary ONU, a primary PON downlink frame sent by a nested OLT, where the primary PON downlink frame carries a primary ONU uplink bandwidth grant and a secondary ONU uplink bandwidth grant; parsing, by the primary ONU, the primary PON downlink frame to acquire the primary ONU uplink bandwidth grant and the secondary ONU uplink bandwidth grant; and sending, by the primary ONU, a secondary PON downlink frame to a secondary ONU, where the secondary PON downlink frame carries the acquired secondary ONU uplink bandwidth grant. The present disclosure achieves an optimal overall performance for the two stages of PONs by considering general conditions of the two stages of PONs, and meanwhile ensures a maximum available bandwidth for the two stages of PONs during formulation of bandwidth grants.

摘要： Embodiments of the present disclosure provide a data synchronization method and system, and an optical network unit. An ONU receives synchronization data that is transmitted by a first OLT through a GEM port corresponding to a predetermined GEM port ID or a logical link corresponding to a predetermined LLID, and stores the synchronization data. When a fault occurs on the first OLT or on a backbone optical fiber connected to the first OLT, the ONU transmits the synchronization data to a second OLT so that the second OLT recovers services according to the synchronization data.
