    摘要： The present disclosure relates to a device and method for RDMA. Specifically, the disclosure proposes a network device, which is configured to transmit an outgoing packet to another network device. In particular, the outgoing packet is a QUIC based packet, which comprises a UDP header, a QUIC header and a QUIC payload. In particular, the UDP header of the outgoing packet comprises an indication that indicates that the QUIC payload of the outgoing packet comprises one or more RDMA transactions. Further, the QUIC payload of the outgoing packet comprises the one or more RDMA transactions. In this way, a solution to run RDMA over the QUIC transport protocol without affecting other applications is provided.

    摘要： This application provides a system and a method for accessing a remote resource. The system includes a local node and a remote node. The local node is configured to: determine a resource access request, where the resource access request includes a resource access operation and an address that is of the local node and that is pointed to by the resource access operation; determine an address of a corresponding remote node; send an operation packet to the remote node, where the operation packet includes the resource access operation and the address of the remote node; and receive an operation result packet sent by the remote node, and determine an operation result based on the operation result packet. The remote node is configured to: receive the operation packet; and execute the resource access operation to obtain an operation result, and send an operation result packet to the local node. By using the system and method provided in this application, a memory, a hard disk, and other resources on the remote node can be directly and quickly accessed in a manner of the delivered resource access request, to avoid problems of a large access delay, a cumbersome process, and low processing efficiency.

    摘要： This application provides a data transmission method and system, to improve data transmission efficiency. The data transmission method provided in this application is an implementation method used when a plurality of communications submodules communicate in a parallel manner. A second communications submodule in the plurality of communications submodules sends, to a hardware queue, data that needs to be sent to a first communications submodule. The first communications submodule obtains the data from the hardware queue when a state of writing data into the hardware queue is triggered. The hardware queue may be a hardware queue in a first processor for running the first communications submodule or a hardware queue in a second processor for running the second communications submodule. In the method, the second submodule does not need to send a notification message to the first submodule to indicate that data has been sent, to reduce a delay of communication between the second submodule and the first submodule, thereby improving communication efficiency.
