The invention provides a DMA (Direct Memory Access) message transfer method, which can be applied to a network card. The method comprises steps: a control core allocates a split packet buffer area for each data core from a memory; when the network card receives the message, the data core receives a message processing message of a network accelerator, length information of the message is acquired from the message, and if the message length is smaller than a preset message length, the message is stored in the split packet buffer area corresponding to the data core; if the message length is more than or equal to the preset message length, a DMA controller is started to execute DMA operation to transfer the message to a server; if the total length of all messages in the split packet buffer area corresponding to the data core is more than or equal to the preset message length, the DMA controller is started to execute DMA operation to transfer the message to the server; and if the total message length is smaller than the preset message length, no operation is carried out. The DMA operation times can be effectively reduced, the effective utilization rate of the PCIE channel bandwidth is improved, and the packet receiving rate of network card small packets is enhanced.
