Abstract: This application describes examples of a data processing method and apparatus. In one example, 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 a duration in which the network device stops buffering a second data packet is greater than a 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.

Abstract: 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.
