Abstract:
The present invention provides a data transmission method, device, and system, to perform DMA data transmission between an I/O device and multiple host devices. DMA memory addresses of the multiple hosts are mapped, to virtual addresses in a global virtual address space, a DMA memory address and a target host that correspond to the DMA virtual address are determined according to a correspondence among DMA virtual addresses, DMA memory addresses, and hosts; the DMA virtual address in the DMA packet is modified to the DMA memory address mapped to the DMA virtual address; and the modified DMA packet is sent to the target host. DMA data transmission between an I/O device and multiple hosts can be implemented, utilization of the I/O device is improved, and application scenarios of network transmission are expanded.

Claim (Index 15):
The data transmission device according to  claim 14 , wherein the permission information of the DMA packet comprises a type of the DMA packet, a permission identifier of the DMA packet, or an identifier of a host sending the DMA packet.
