Abstract: This application provides a congestion control method, a network device, and a network interface controller. In the congestion control method performed by a first intermediate device, the first intermediate device receives a first data packet sent by a sending device, sends the first data packet to a receiving device along a first path, receives a first acknowledgment packet that is sent by the receiving device and that is used for acknowledging the first data packet, and determines a congestion degree of the first path based on a congestion mark in the first acknowledgment packet. The first intermediate device changes a window value and sends the changed first acknowledgment packet to the sending device. According to a solution provided in this application, a speed of transmitting a data packet is adjusted based on a congestion degree of a communication path and a quantity of bytes of the data packet.
