Abstract: A data packet detection method, a device, and a system are disclosed. The method includes: receiving first control information sent by a controller; receiving a first data packet sent by a previous-hop network device of a first network device, where the first data packet includes first detection information, and the first detection information includes a first detection node identifier, a first sequence number, and first collection information; determining, based on the first collection information, first collected data corresponding to the first collection information, and updating the first detection node identifier; and sending, to a next-hop network device of the first network device, the first data packet carrying the updated first detection information. This implements information telemetry on a data packet on a transmission path.

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 the 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.
