Description
Technical field
The present invention relates to data communication field, the especially a kind of method and server of transfer of virtual desktop.
Background technique
With the development of virtualization technology, in scene of handling official business or impart knowledge to students, the usage mode of previous more independent PC machine, by
Step is substituted by virtual cloud desktop.By will receive virtual cloud desktop server in computer resource unification, terminal only makees desktop number
According to display and operating interactive, to achieve the purpose that centralized management and save the cost.
Virtualization technology mainly by the resource of a server is fictionalized more logics virtual machine (VM:
virtual machine).Then the desktop of virtual machine is shown by network transmission to terminal, and in terminal.And
Terminal returns the virtual machine in server to the operation of desktop by network transmission.Reach terminal user operating experience and solely
Vertical PC the same effect.
But during actual environment run action, by high resolution pictures, HD video frame number, low-bandwidth environment
Equal constraints.It is difficult to directly accomplish the process experience of not Caton.Such as: the number of the desktop picture sequence generation per second of cloud desktop
It is very huge according to measuring, by taking 21 cun of liquid crystal display as an example (assuming that the desktop resolution ratio of cloud desktop setting is 1920*1080), one
Frame desktop picture data are 1920*1080*24/8/1024/1024=5.93MB, it is assumed that the image sequence per second for generating 15 frames,
The image data amount generated for so 1 second is 5.93*15=88.95MB.In nearly 100 concurrent and practical schools and office ring
It is difficult to reach real 100,000,000 bandwidth in border.
For existing problem, prior art is mainly solved by schemes such as image classification, data compressions,
One, image classification
By the way that different image types to be made to different processing: such as the image of text class by cutting white bottom region with
Character zone separately transmits.Make homochromy block for colored class image to merge, then transmit respectively.For different images type
Judgement relatively depends on image full figure elder generation scanning analysis, low efficiency at present.
Two, data compression
Have the algorithm of some data compressions at present, for example be H.264 suitble to pressure video data, for example LZ is suitble to press textual data
According to JPEG is suitble to press image data, and most of is the compression damaged.
Fig. 1 is the schematic diagram of virtual desktop transmission in the prior art, in conjunction with above-mentioned technical solution, first by the pixel of image
Coding switchs to binary digit, then turns electric pulse by number.Metal or optical fiber can be used to make transmission as cable in implementation process to be situated between
Matter, but source is still binary Digital Transmission.Especially optical fiber, though optical transport is utilized, what is passed is still the pulse of light on and off
Information.
Above-mentioned prior art be still substantially improved on the pixel data of image, and eventually by network bytes or
Pixel is sent.There is operation to be distorted with data portion, it is cost that different type, which makees different experience effects,.And these methods,
For current production to experience as king, acceptance of the users is to be difficult to meet market demands under the leading environment of competition.
