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 2):
The computer system according to  claim 1 , wherein the DMA memory addresses of each host are divided into DMA memory address intervals, the global virtual address space comprises multiple non-overlapping virtual address intervals, and each DMA memory address interval of said each host corresponds to one and only one of the virtual address intervals in the global virtual address space, and wherein the operation of determining comprises:\n identifying a target DMA memory address interval mapped to a virtual address interval to which the target DMA virtual address belongs; and identifying the target host and the target DMA memory address based on the target DMA memory address interval.
