    Abstract: A packet processing method includes generating, by a processor of a network device, a first encoding task based on M original packets in a to-be-processed first data stream, where M is a positive integer, and where the first encoding task instructs to encode the M original packets; and performing, by a target hardware engine of the network device and based on the first encoding task, forward error correction (FEC) encoding on the M original packets to obtain R redundant packets, where R is a positive integer.

    Abstract: Embodiments of this application provide a data stream transmission method. The method includes a sending device that dynamically determines a packet-loss-concealment policy based on first path status information of a path used to send a data stream. The sending device generates a packet-loss-concealment packet for the data stream according to the packet-loss-concealment policy. The sending device sends the data stream on the path. The data stream includes an original packet and the packet-loss-concealment packet. Therefore, when receiving the data stream, a receiving device decodes the data stream according to the packet-loss-concealment policy received from the sending device, and recovers, by using the packet-loss-concealment packet, an original packet lost in a transmission process. This effectively improves a packet loss recovery effect, and improves user experience.

    Abstract: Embodiments of this application disclose a chunking method and an apparatus for implementing the method. According to the method provided in the embodiments of this application, a first data segment of a first length may be determined starting from a header of a to-be-chunked data flow, a data distribution characteristic of the first data segment is determined based on character values of all characters in the first data segment, and then a chunking position is determined for different data distribution characteristics by using different methods. In this way, a data flow can be better chunked, so as to enhance a deduplication effect.
