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: The present invention discloses a bandwidth adjustment method and a related device, so as to flexibly adjust a bandwidth. A controller obtains behavior characteristic statistics sent by an end cloud node device, and obtains bandwidth resources remaining on a system. The behavior characteristic statistics are a statistical result indicating behavior characteristics of occupying network bandwidth resources by a user when accessing the end cloud node device. The controller determines a bandwidth adjustment amount of the end cloud node device according to the behavior characteristic statistics and bandwidth remaining on the system. The controller sends a bandwidth adjustment instruction to a first network device. The bandwidth adjustment instruction is used to instruct the first network device to adjust, according to the bandwidth adjustment amount, a bandwidth allocated to the end cloud node device by a network device on a transmission link.
