DATA FORWARDING METHOD, DEVICE AND SYSTEM

A kind of data forwarding method, apparatus and system technical field

The present invention relates to communication technique field, more particularly to a kind of data forwarding method, apparatus and system.Background technology

Virtualization technology（Virtualization the multiple virtual machines of generation) are simulated on a physical computer using software engineering（Virtual Machine, abbreviation VM), each VM can as physical computer installation operation system, application software is installed, various programs are run.Multiple VM can be run on a physical computer simultaneously, and other side is not perceived from each other, is isolated from each other, can only be communicated with one another by network, the same just as two physical computers.Multiple VM performance summation is no more than the physical computer where it.

In virtualization technology, multiple VM software is simulated on a physical computer virtual monitor device（Virtual Machine Monitor, abbreviation VMM).Because the property that virtual technology introduces the application program of operation in this intermediate layer of VMM, VM is different, the performance loss brought is virtualized also different.The application program of a large amount of CPU computings is carried out, its run time behaviour loss in VM is smaller.A large amount of input/output are carried out with the external world（Input/Output, abbreviation I/O) communication application program（Such as network communication or disk read-write）, its in VM run time behaviour loss it is larger.Because virtualization technology can bring more preferable integrated cost advantage, wireless telecommunications industry starts to use virtualization technology on a large scale.But in wireless telecommunications system, application program generally requires to carry out substantial amounts of network communication, there is substantial amounts of data throughput, therefore runnability of the application program in VM can decline to a great extent.

It is the cooperation using standard Virtual I/O communication mechanisms by communication two ends inside and outside VM in the prior art, the exchange of data is realized with efficient interface, the simulation process for simplifying virtual hardware reduces the loss of I/O processes.But although this scheme reduces loss, but it is lost still very big.Quote single I/O virtualizations again in the prior art（Single Root I/O Virtualization, abbreviation SR-IOV) hardware leads directly to technology by physical computer On hardware directly give VM using rather than by VMM fictionalize Lai virtual hardware.Driver in this technology in VM can directly drive physical network card, carry out transmitting-receiving package operation.VM has directly bypassed VMM pilot process using physical hardware so that performance loss minimizes.But it is due to that VM needs to perceive different physical hardwares, for the different corresponding drivers of hardware installation, VM is also required to together change when HardwareUpgring or change, exploitation, maintenance, deployment to VM etc. produce considerable influence, so that operating efficiency is reduced, practical operation is got up also cumbersome.The content of the invention
