摘要： This application provides a buffer configuration method and a switching device, to ensure no packet loss, and belongs to the field of network technologies. The method includes: sending, by a first switching device, a first measurement frame to a second switching device; receiving, by the first switching device, a second measurement frame sent by the second switching device, where the second measurement frame is generated through triggering based on the first measurement frame; determining, by the first switching device, a buffer configuration parameter based on the first measurement frame and the second measurement frame; and setting, by the first switching device, a local buffer based on the configuration parameter. This application is used to automatically configure a buffer of a switching device, thereby reducing buffer space without packet loss.

摘要： Embodiments of this application provide a transmission control method, an apparatus, and a system, to ensure that a receive end continuously outputs data packets. The method includes: A first communication apparatus obtains a sampling cycle. The sampling cycle is a time interval at which the first communication apparatus samples occupancy of a first buffer. The first buffer is used to store a data packet of a first priority. The first communication apparatus determines occupancy of the first buffer at a first sampling moment based on the sampling cycle. The first communication apparatus determines first duration based on the sampling cycle and the occupancy of the first buffer at the first sampling moment. The first duration is duration for which a second communication apparatus stops send data to the first communication apparatus. The first communication apparatus sends first indication information to the second communication apparatus based on the first duration. The first indication information is used to control the duration for which the second communication apparatus stops send data to the first communication apparatus.

摘要： This application relates to the field of communication technologies, and provides a collective communication method and a communication apparatus, to implement short-distance communication and save communication resources. The method includes: A first terminal device receives at least one second packet from a first network device, where the second packet includes information about a first process and information about a network device corresponding to the first process, the first process is used to execute a first task, and the information about the network device corresponding to the first process is information about a network device to which a terminal device including the first process belongs. The first terminal device determines a third packet based on the at least one second packet, where the third packet includes information about a target network device and information about all first processes that correspond to the target network device and that execute the first task, and the target network device is at least one of network devices corresponding to the first task. The first terminal device sends the third packet to the first network device.

摘要： Embodiments of this application disclose a data processing method and a related device, to improve stability and reliability of data transmission. In embodiments of this application, the method includes: If a target buffer that is corresponding to a target priority and that is on a network device reaches a first threshold, the network device sends a pause message to an upstream device, so that the upstream device stops sending a first data packet corresponding to the target priority. If duration in which the network device stops buffering a second data packet is greater than preset duration, and the target buffer falls back below a second threshold, the network device sends a sending resumption message to the upstream device, so that the upstream device sends a third data packet corresponding to the target priority. The second data packet is a data packet that is buffered after the network device sends the pause message and before the network device sends the sending resumption message and that is corresponding to the target priority.
