Abstract: The present application discloses a method, a system and a related device for transmitting an OMCI message. In the method, an optical line terminal device sends configuration information to an optical network terminal device, where the configuration information is configured to instruct the optical network terminal device to configure a multicast port on the optical network terminal device to an enabled status so as to establish a multicast channel. The optical line terminal device sends an OMCI message that includes multicast information to the optical network terminal device through the multicast channel, where the multicast information includes a multicast port identifier and the multicast port identifier is configured to reflect a mapping between the OMCI message and the multicast port.

Abstract: A communication method and a communication apparatus are provided. The method includes: An optical line terminal (OLT) may obtain a cycle period and a data amount of periodic data, and allocate a first slot and a second slot based on the data amount of the periodic data and the cycle period, where the first slot is used to transmit the periodic data, the second slot is used for windowing, and the second slot is a part or all of slots other than the first slot in the cycle period. The OLT uniformly allocates the first slot used to transmit the periodic data and the second slot used for windowing.

Abstract: A bandwidth allocation method and a related device are disclosed. An exemplary method includes: when a total sum of a cumulative sum of fixed bandwidth configuration upper limits of traffic bearing entities and a cumulative sum of assured bandwidth configuration upper limits of the traffic bearing entities is greater than a maximum bandwidth value of a passive optical network (PON) port of a piece of central office equipment, determining, by the central office equipment based on a bandwidth configuration upper limit of each traffic bearing entity and a required bandwidth value of the traffic bearing entity, a bandwidth value actually allocated to the traffic bearing entity. In this way, a part of bandwidth is allocated to each traffic bearing entity. This avoids a case in which no bandwidth is allocated to some traffic bearing entities. Therefore, resource allocation is more appropriate.

Abstract: A method for authenticating an optical network unit (ONU) and devices for an optical line terminal (OLT) and an optical network unit (ONU) where an ONU is not allowed to be migrated in an authorized manner to an OLT of another vendor for use and binds the ONU and a particular vendor. The method also includes, when an ONU goes online, obtaining, by the OLT, first vendor information of the ONU, where the first vendor information is vendor information of a vendor to which the ONU belongs; comparing, by the OLT, the first vendor information with second vendor information, where the second vendor information is vendor information of a vendor to which the OLT belongs; and if a comparison result indicates that the OLT and the ONU belong to different vendors, determining, by the OLT, that authentication on the ONU fails.

Abstract: A bandwidth assignment method and apparatus, and an optical network system are disclosed. The method includes: setting a maximum bandwidth grant size and a maximum burst bandwidth grant size for an optical network unit; receiving a bandwidth assignment request of the optical network unit; and when an optical line terminal determines, according to the bandwidth assignment request, that a bandwidth grant size requested to be assigned in the bandwidth request is greater than the set maximum bandwidth grant size and less than or equal to the set maximum burst bandwidth grant size, determining, by the optical line terminal, in response to the request, to assign the requested bandwidth grant size to the optical network unit. Therefore, timely and accurate transmission of massive uplink burst data traffic is ensured, a transmission delay is reduced, service performance is improved, and system bandwidth utilization is greatly increased.

Abstract: An apparatus and a method for detecting an uplink optical signal. The apparatus includes a memory and a processor, where the processor is configured to determine a remaining bandwidth in a target uplink frame as a test window, where the remaining bandwidth in the target uplink frame indicates an unallocated bandwidth in the target uplink frame, and detect an uplink optical signal in the determined test window. Therefore, a remaining bandwidth obtained after bandwidth allocation in a target uplink frame is used to detect an uplink optical signal, which can effectively use a resource without the need of independently opening a test window and using an extra resource to detect the uplink optical signal, thereby avoiding waste of a resource and improving test efficiency.
