Abstract: A service data transmission method, a related device, and a digital processing chip, to reduce a transmission latency of service data. The method in the embodiments includes the following steps: a first device encapsulates a channel frame in a transmission frame, where the channel frame is used to carry service data. Next, the first device sends the transmission frame to a second device. A transmission manner of the channel frame is a non-decapsulation manner between an optical transport network and an access network.

Abstract: A service data processing method and apparatus is disclosed. A data frame is divided into code blocks with smaller granularity, and service data is mapped to a corresponding quantity of code blocks in the data frame based on a service requirement. In addition, the data frame is used to indicate a location of a code block carrying the service data. In one manner, a code block in a payload area of the data frame is divided into a data code block and an overhead code block, and the overhead code block is used to indicate a location of a data code block carrying the service data. In the another manner, an indication field is configured in an overhead area of the data frame to indicate a location of a code block that carries the service data and that is in the payload area of the data frame.

Abstract: Embodiments provide a service processing method and apparatus. According to the service processing method, a number of code blocks of a client service may be mapped to a FlexE subslot, and a FlexE subslot overhead is generated, so that the client service mapped to the FlexE subslot and the FlexE subslot overhead are sent through a physical channel, and a low-rate service is carried. Compared with carrying a low-rate service by directly using an entire FlexE slot, carrying the client service by using a number of FlexE subslots into which the FlexE slot is divided can improve bandwidth utilization.

Abstract: Embodiments of this application disclose a data processing method, an optical transmission device, and a digital processing chip, for improving service transmission performance. In the data processing method, an optical transmission device compresses a to-be-transmitted data stream to obtain a compressed data stream. The optical transmission device then obtains a size of a first payload area corresponding to the compressed data stream and maps the compressed data stream to a data frame, where the data frame includes an overhead area and a payload area. The payload area includes the first payload area and a second payload area. The second payload area carries the compressed data stream, and the first payload area carries a forward error correction (FEC) code. The data frame is then transmitted by the optical transmission device.

Abstract: This application discloses a service data processing method and device. A transmit-end device may generate an optical transport network (OTN) encapsulated signal carrying service data, and generate at least n FlexO (flexible optical transport network) frames based on the OTN encapsulated signal and send the at least n FlexO frames, where r FlexO frames in the at least n FlexO frames carry service check data, and the service check data may be used to restore the service data when bit error rates of k FlexO frames are greater than a reference bit error rate. In this way, if no more than r physical ports included in a FlexO group interface fail, or a bit error rate of no more than r FlexO frames is greater than the reference bit error rate due to another reason, a receive-end device may restore the service data through a received FlexO frame.

Abstract: A method and an apparatus for transmission using an interface, and a device. The method includes: obtaining a byte block stream, where byte blocks in the byte block stream are of a predetermined byte length; mapping the byte block stream to corresponding timeslots, where each timeslot corresponds to one byte block; distributing the byte block stream mapped to the timeslots; processing the distributed byte block stream based on an interface type configured for a physical interface; and sending the processed byte block stream. In the embodiments, data is transmitted based on a byte block distribution mechanism, to support different interface types, and a coupling relationship between service adaptation and a physical layer is decoupled, so that evolution and extension of transmission interface types do not affect a service adaptation procedure, thereby simplifying a transmission system.

Abstract: The present invention discloses a service transmission method, a network device, and a network system. The method includes: obtaining, by a first network device, a client service of FlexE, and obtaining clock information corresponding to the client service; mapping, by the first network device, the client service and the clock information to a timeslot of a FlexE frame, where the client service and the clock information occupy a same timeslot and/or different timeslots; and sending, by the first network device, the FlexE frame to a second network device. Therefore, service clock information can be transparently transmitted in flexible Ethernet by using the method of the present invention.
