Abstract: A data transmission method is provided. The method includes: a network interface card of a source device obtains a first notification message and a second notification message, wherein the first notification message indicates that a first to-be-processed remote direct memory access (RDMA) request exists in a first queue of the source device, the first queue stores a request of a first service application in the source device, the second notification message indicates that a second to-be-processed RDMA request exists in a second queue of the source device, and the second queue stores a request of a second service application in the source device; and the network interface card determines a processing sequence of the first queue and the second queue based on service levels, and sends the first to-be-processed RDMA request and the second to-be-processed RDMA request to a destination device according to the processing sequence.
