Abstract: This application provides a network device, including a buffer module, a counting module, a control module, and a sending module. The buffer module includes N queues, configured to buffer M data streams, where N is less than M. The counting module includes M counters, the M counters are in a one-to-one correspondence with the M data streams, and the M counters are configured to count buffer quantities for the M data streams in the N queues. The control module is configured to: when a count value on a first counter exceeds a corresponding threshold, discard a to-be-enqueued data packet of a data stream corresponding to the first counter, or control the sending module to send pause indication information to an upper-level control module. On one hand, resource consumption of the network device can be reduced. On the other hand, buffer pressure of the network device can be released.

Abstract: This application provides a data exchange method and apparatus. The method includes: A source node receives flow indication information from a first switching node, where the flow indication information indicates that congestion occurs in a target data flow, and the first switching node is a node in a switching path of the target data flow. The source node sends multiple pieces of write data information and multiple data blocks of the target data flow to multiple switching nodes, where the multiple pieces of write data information indicate the multiple switching nodes to store the multiple data blocks and stop forwarding the multiple data blocks. The multiple switching nodes store the multiple data blocks. The multiple switching nodes receive multiple pieces of scheduling information from a destination node, where the multiple pieces of scheduling information are used to schedule the multiple data blocks.
