摘要： In a service signal processing method, an optical network unit (ONU) receives a service signal; maps the service signal to a flexible optical service unit frame; and sends a first passive optical network transmission convergence frame to an optical line terminal (OLT), where the flexible optical service unit frame is encapsulated in the first passive optical network transmission convergence frame, and where the flexible optical service unit frame is used to carry the service signal in a passive optical network (PON) and an optical transport network (OTN). In this application, the flexible optical service unit frame can be transmitted in both the PON and the OTN, and the ONU and the OLT do not need to parse the service signal.

摘要： A data transmission method in an optical transport network includes: mapping first-type service data to a payload block at a specific location in a plurality of consecutive payload blocks, where the plurality of consecutive payload blocks occupy a payload area of an optical data unit (ODU) frame; mapping second-type service data to a payload block at any location in the plurality of consecutive payload blocks other than the at least one specific location; mapping the ODU frame to an optical transport unit (OTU) frame or a flexible OTN (FlexO) frame; and sending the OTU frame or the FlexO frame. In an applicable scenario, service data is transmitted in a hybrid manner.

摘要： A method and an apparatus determines a network device receiving a first signal and at least one second signal, wherein the first signal carries data to be sent through a first flexible Ethernet interface. A first physical layer clock is determined based on the first signal. A second physical layer clock is determined based on the at least one second signal or the first physical layer clock and the at least one second signal. The first physical layer clock or the second physical layer clock is used as a sending clock of a non-flexible Ethernet interface. The network device includes the first flexible Ethernet interface and the non-flexible Ethernet interface.

摘要： Embodiments of this application provide a signal frame processing method and a related device. A sink node performs delay compensation on a received service, so that delay variation generated in a transmission process of the service can be effectively eliminated. The method in embodiments of this application includes the following steps. First, the sink node receives a signal frame. A payload area of the signal frame is used to bear a target service, and an overhead area of the signal frame includes a node quantity field. Then, the sink node determines, based on the node quantity field, a quantity of nodes through which the target service passes during transmission. Further, the sink node performs delay compensation on the target service based on the quantity of nodes.

摘要： A data processing method, a communications device, and a communications system, where in a process of transmitting a packet service, a code block stream carrying the packet service is first obtained, then, rate adaptation is performed on the obtained code block stream, and finally, the rate-adapted code block stream is mapped to an optical channel payload unit (OPU) signal. Compared with a mapping manner in which a Generic Framing Procedure (GFP) is used, the data processing method, the communications device, and the communications system feature low processing complexity and/or high bandwidth utilization.

摘要： Embodiments of the present invention provide a method and an apparatus for transmitting and receiving a client signal in an optical transport network. In the transmission method, a received client signal is mapped into a variable-rate container OTU-N, wherein a rate of the OTU-N is N times as high as a preset reference rate; and then, the variable-rate container OTU-N is split into N optical sub-channel transport units OTUsubs by column, where a rate of each OTUsub equals to the reference rate; next, the N optical sub-channel transport units OTUsubs are modulated onto one or more optical carriers; at last, the one or more optical carriers is transmitted through a fiber.

摘要： The embodiments of the present invention disclose methods and apparatuses for mapping processing and de-mapping processing in an optical transport network. a Low Order Optical Channel Data Unit (LO ODU) signal is mapped into a payload area of an Optical Channel Data Tributary (ODTU) signal in units of M bytes. M is equal to the number of time slots of a High Order Optical Channel Payload Unit (HO OPU) that are to be occupied by the ODTU signal, and M is an integer larger than 1. Overhead information is encapsulated to an overhead area of the ODTU signal. Thereafter, the ODTU signal is multiplexed into the HO OPU. In this way, an efficient and universal mode for mapping the LO ODU to the HO OPU is provided.
