Description
Technical field
The present invention relates to a kind of remote desktop figure accelerated method, belong to technical field of virtualization.
Background technology
In recent years, with cloud computing and the fast development of virtualization, the application of cloud desktop is also more and more extensive.Cloud desktop can
So that data space, management service are distributed to operator in the way of providing desktop, be adapted to provide for thin client, flat board,
The simple portable equipment such as mobile phone, can also be supplied to traditional PC to use.For company, can be realized using cloud desktop makes
All data are all in cloud platform, it is ensured that information security.All application programs and data, can be by attendants all in cloud platform
Unified maintenance and management, reduces maintenance and management expense.Cloud desktop application thin client is more more energy efficient than traditional PC, and relatively
The maximum benefit of conventional desktop is to realize rapid deployment, need to only match somebody with somebody display, keyboard, mouse, plug netting twine and can be achieved with normally
Office.
For cloud desktop, the fluency of desktop determines to be directed to figure acceleration side in the experience of user, current cloud desktop
Face implementation method has the following two kinds：One is the method by compression, contracts and then is decompressed at client ends in server side pressures
And show, another is to install high performance video cards at server ends, is directly mapped to virtual machine, is then directly shown by client
Show.Calculating and display performance of the first method to client ends are required, and are had necessarily for the limited client of computing capability
Pressure.Second method Consumer's Experience is best, but cost is too high.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of remote desktop figure accelerated method；
Summary of the invention：
Different figure accelerated modes is used for different clients, the present invention there are two kinds of accelerated modes, one kind is pair
In the not high client of performance, by virtual desktop after figure is rendered, recompression transmission, the data of transmission are to be changed on desktop
Part, part is not changed without transmission.Second is that, for the preferable client of display performance, will directly be rendered without figure
Initial data be transferred to client, client oneself is rendered to be shown again, for reduce bandwidth occupancy, be equally that will change portion
Divide after being compressed and transmit.
The technical scheme is that：
A kind of remote desktop figure accelerated method, including：For the not high client of video card capabilities, by the change of virtual desktop
The compression after figure is rendered of dynamic part is transferred to client；For the high client of video card capabilities, by all of virtual desktop
Initial data is transferred to client, to reduce bandwidth occupancy, the variation in all initial data by client by virtual desktop
Part renders by figure and shown.
The present invention uses different Graph Acceleration Technologies for different clients, can effectively lift user's desktop experience
Degree, compatible a variety of client platforms improve the Experience Degree of user.
According to currently preferred, the remote desktop figure accelerated method also includes the computational of detection client successively
Energy and display performance, including:
(1) the calculating performance of client is detected, including：In client initialization, the embedded compression of one section of operation is conciliate
Test program is pressed, run time is counted, if run time, which is less than, calculates performance threshold, judges that the client calculates performance and expired
Foot is required；Otherwise, then judge that the client calculates performance and is unsatisfactory for requiring；The span for calculating performance threshold is 0-1s；Meter
Performance threshold is calculated according to actual test, the general client for calculating performance within 1S, which is met, to be required, the client more than 1S is not
Meet and require.
(2) detected that client is calculated after performance, detected the display performance of the client, including：Perform one section it is embedded
Display card test program, the display card test program includes reading core frequency, video memory bit wide, video memory capacity, if core frequency is big
It is more than 128bit in 900MHz, video memory bit wide and video memory capacity is more than 1GB, then judges the client video card as high performance video cards,
Meet and oneself carry out the requirement that figure is rendered, otherwise, then judge the client video card as low performance video card, be unsatisfactory for oneself and carry out
The requirement that figure is rendered.
According to currently preferred, the remote desktop figure accelerated method also includes synchronous judging the computational of client
Energy and display performance, including：The calculating performance of the client of test, display performance are passed into service end, service end can be carried out
Correlation computations and judgement, integrate the judge to client, and evaluation result is passed into client, and evaluation result includes video card
Energy is high, video card capabilities are not high, and client sets corresponding mark to evaluation result.Extended meeting determines how to handle according to mark afterwards
The data that service end is sended over.
According to currently preferred, for the not high client of video card capabilities, service end is extracted empty after figure is rendered
Intend the data of desktop, and contrasted with previous frame data, difference section is taken out, using graphics compression algorithm by difference section
Be compressed, and by the data transfer after compression to client, client compressed after data after, first decompressed, then
It is a frame data by the data convert after decompression, is directly displayed by client on desktop.
The advantage designed herein is, reduces video card render process, improves user experience.
According to currently preferred, for the high client of video card capabilities, the data of service end extraction virtual desktop, the number
According to being the initial data that is rendered without figure, and contrasted, difference section is taken out, using graphics compression with previous frame data
Difference section is compressed by algorithm, and by the data transfer after compression to client, client is obtained after data, is first solved
Pressure, then by the data convert after decompression be a frame data, and be directly passed to video card, then by video card render automatically after be shown to table
On face.
Beneficial effects of the present invention are：
1st, the present invention uses different Graph Acceleration Technologies for different clients, can effectively lift user's desktop body
Degree of testing, compatible a variety of client platforms.
2nd, the present invention can significantly reduce the requirement to the network bandwidth using the graphics compression algorithm of optimization, improve network
The utilization rate of resource.
3rd, the present invention is for the not high client of display performance, and speed-raising is obvious, can be obviously improved desktop response speed.
