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: A BRAS system-based packet encapsulation method includes obtaining user access information when receiving a user access protocol packet and performing VXLAN GPE encapsulation on the user access protocol packet based on the user access information. The encapsulation structure includes a user information header that is used to store the user access information, and a quantity of bytes occupied by the user information header is less than or equal to 12. In this application, the foregoing encapsulation structure is used to encapsulate a packet.

Abstract: Embodiments of this application disclose a congestion control method and a related device. A Transmission Control Protocol offload engine TOE sends a congestion control notification to a central processing unit CPU, where the congestion control notification instructs the CPU to obtain a target parameter, and the target parameter is used by the CPU to generate a congestion control calculation result. The TOE obtains the congestion control calculation result returned by the CPU, where the congestion control calculation result includes a congestion control window value. The TOE sends a packet based on the congestion control window value. In this application, the TOE and the CPU implement congestion control together. When a new congestion control algorithm emerges, the new congestion control algorithm may be applied without changing a structure of the TOE. Therefore, in this application, an upgrade period of the congestion control algorithm can be shortened, and flexibility can be improved.

Abstract: A data reading method includes receiving, by a controller of a memory, a read operation request carrying a first address; performing, by the controller, N read operations on the first address, and obtaining N pieces of data read by the N read operations; and determining, by the controller, whether the N pieces of data are consistent. The method further includes sending, by the controller, response information used to respond to the read operation request if the controller determines that the N pieces of data are consistent, where the response information includes any one of the N pieces of data. The controller may perform T random read operations between any two consecutive read operations of the N read operations to avoid data leakage during reading. If the N pieces of data obtained by performing the N read operations are inconsistent, the memory may send abnormal alarm information to respond to the read operation request to avoid data tampering. An apparatus including a controller and different modules for performing the operations of the method are also disclosed.
