Abstract: A data transmission method implemented by a network device, where the data transmission method includes receiving a first data packet sent by a transmit end, buffering the first data packet to a low-priority queue when the first data packet is sent by the transmit end during a first round-trip time (RTT) of a data transmission phase between the transmit end and a receive end, receiving a second data packet from the transmit end, buffering the second data packet to a high-priority queue when the second data packet is not sent by the transmit end during the first RTT, and forwarding the second data packet in the high-priority queue before the first data packet in the low-priority queue.

Abstract: A first node obtains a corresponding physical address based on a first virtual address in a first request. The first request may be sent by an application in the first node, and is used to request to read data of a second node or request to write data to the second node. Then, the first node sends a second request corresponding to the first request to the second node based on a first mapping relationship. Because the bus address indicates a virtual address corresponding to an instance of the second node, when the virtual address may be accessed by the first node based on the first request, the virtual address may be accessed by the second node, or may be accessed by another node based on a request, to implement address sharing in data access.

Abstract: A congestion control method and apparatus, a device, and a storage medium, where the congestion control method includes sending first data packets to a receive end, where a quantity of the first data packets is the first value, receiving a plurality of second data packets corresponding to all or a portion of the first data packets, where the second packets include one or more third data packets and one or more fourth data packets, and adjusting, by a transmit end, a congestion window based on the second data packets to adjust a value of the congestion window to a second value.

Abstract: A communication method includes obtaining, by a source remote direct memory access (RDMA) network interface card (RNIC), to-be-transmitted data sent by a source virtual RNIC (vRNIC), obtaining, by the source RNIC, identity indication information of a destination vRNIC and packet forwarding information, and encapsulating, by the source RNIC, the to-be-transmitted data to obtain a target packet, and sending the target packet to a destination RNIC, where the destination vRNIC is a vRNIC running on the destination RNIC.

Abstract: A network device calculates an idle forwarding capability of a target egress queue or a target egress port on the network device, where the idle forwarding capability represents a difference between an upper limit of a data forwarding amount of the target egress queue or the target egress port and a current actual forwarding amount. Then, the network device obtains a first packet carrying an adjustment request, and when the first packet does not have a preset mark, the network device obtains a decision result based on the idle forwarding capability and the adjustment request.
