Abstract: A data transmission method includes encapsulating, by a first device, first target data into N remote direct memory access (RDMA) packets according to an RDMA protocol, sequentially sending, by the first device, the N RDMA packets to the second device according to a packet sequence number (PSN) sequence of the N RDMA packets, where each of the N RDMA packets carries a first data write address, and the first data write address is an address for writing data in each of the N RDMA packets into the second device such that the second device directly obtains the first data write address in each RDMA packet from the RDMA packet, and writes the target data into storage space corresponding to the first data write address.

Abstract: In a packet transmission method and an apparatus for implementing the method, packets in different groups have different source port information, and a header carried in each packet carries a write address of the packet in a memory in a destination server. In this way, the to-be-sent packets are forwarded on different paths.

Abstract: A method includes that an electronic device displays a first interface after detecting a first operation performed by a user on the electronic device. The first interface includes a first element and a second element. The electronic device displays at least one transition interface and then displays a second interface after detecting a second operation performed by the user on the first interface. The second interface includes the second element and a third element, the transition interface includes the second element, and the second element does not include an element in a status bar on the first interface, the transition interface, or the second interface.

Abstract: The present invention discloses a method and a device for generating a CNM, so as to improve a processing rate of a congestion problem. The method includes: monitoring a data volume of an output queue at a congestion point CP; monitoring a rate of a data stream corresponding to at least one congestion reaction point RP connected to the CP, and when the data volume of the output queue at the CP reaches a congestion threshold, obtaining identification information of a data stream that currently has a highest rate; generating a CNM for the data stream having the identification information, and sending the CNM to an RP corresponding to the identification information, so that the RP reduces, according to the CNM, the rate of the data stream corresponding to the RP.
