Abstract: A network congestion notification method and network node are provided in a network system. The network node receives a remote direct memory access (RDMA) packet, where the RDMA packet carries a source queue pair number corresponding to a transmit end and a destination queue pair number corresponding to a receive end. The network node generates a congestion notification packet when detecting network congestion, where a destination queue pair number of the congestion notification packet is the source queue pair number. Then the network node sends the congestion notification packet to the transmit end so that the transmit end may decrease a sending rate of a data flow to which the first data packet belongs.

Abstract: A method for accessing a memory of a multi-core system, a related apparatus, a system, and a storage medium involve obtaining data from a system memory according to a prefetch instruction, and sending a message to a core that carries the to-be-accessed data. Each segment of data is stored in an intra-core cache based on the prefetch instruction.

Abstract: A data transmission method includes receiving, by a first terminal, a first notification message, where the first notification message notifies the first terminal that a target bicycle is in an available state. The method further includes sending, by the first terminal, a mode setting instruction to a second terminal after receiving the first notification message, where the mode setting instruction instructs the second terminal to enter a riding model. The method further includes receiving, by the second terminal, the mode setting instruction from the first terminal, and entering the riding mode.

Abstract: This disclosure relates to the field of data communication, and provides a network congestion notification method, an agent node, and a computer device. When receiving a first data packet, an agent node adds a source queue pair number to a first data packet to obtain a second data packet, and sends the second data packet to a receive end by using a network node. In a process of forwarding the second data packet, if the network node detects network congestion, the network node generates a first congestion notification packet carrying the source queue pair number, and sends the first congestion notification packet to the agent node. Further, the agent node sends the first congestion notification packet to a transmit end, so that the transmit end decreases a sending rate of a data flow to which the first data packet belongs.

Abstract: The present invention discloses a packet transmission method and user equipment. The method includes: transmitting, by a sending node, multiple packets to a receiving node; receiving multiple acknowledgement packets from the receiving node; after determining, based on the received multiple acknowledgement packets, that a first packet is lost, retransmitting the first packet; and if it is detected that the retransmitted packet is lost, continuously retransmitting, by the sending node, the first packet to the receiving node in a preset time interval for at least twice. According to the solutions of the present invention, the retransmitted packet can be detected and recovered in time after the retransmitted packet is lost, thereby reducing a quantity of times of timeout retransmission, improving a transmission rate, moreover, reducing a packet loss probability of a retransmitted packet, and further reducing a probability of timeout retransmission.
