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 9):
The data transmission method according to  claim 7 , wherein after determining the target host and the target DMA memory address and prior to modifying the DMA packet, the method further comprises:\n determining, according to permission information of the DMA packet and a permission requirement of the target host, that a DMA operation on the target host is permitted.
