Embodiment
In order more clearly to describe technology contents of the present invention, conduct further description below in conjunction with specific embodiment.
Organization Chart is shown in Fig. 1 and Fig. 3, of the present invention based on cloud computing realize remote dummy desktop show system comprise:
Terminal, selects application request and the desktop decoding data receiving is shown in order to send;
Control workbench, for initialize communications resource;
Authentication server, docks with described terminal in order to the control workbench by described and the user identity that uses terminal is authenticated;
Streaming media server cluster, in order to give described terminal by the desktop Data dissemination the coding receiving from virtual machine;
Application server cluster, calculates and the desktop data after coding is sent to described streaming media server cluster in order to carry out virtual machine operation and data cloud;
Data storage server cluster, in order to store desktop data corresponding to each terminal.
As shown in Figure 2, of the present invention based on cloud computing realize remote dummy desktop show method comprise the following steps:
(1) various terminals arrive job control platform by network insertion.
(2) job control platform is mainly responsible for docking of user and authentication server, and a series of resource of initialization, as the communicating by letter of initialization and Streaming Media, initialization are communicated by letter with rear end virtual machine.
(3) after authentication is passed through, virtual machine receives after stream application, and will open the software carrying, that flows obtains, and comprises that quick screen is re-reading, fast coding, network transmission etc., and opens control information receive path simultaneously.
The re-reading step of screen is as shown in Figure 5 fast:
Owing to will supporting that current screen is encoded into real-time streams, therefore the high performance screen of grabbing is one of key realizing.In the present invention, by multiple combination mode by screen quick obtaining.Common server is by Hook Gdi function and DirectX(Direct extension, the Multimedia Programming interface being created by Microsoft) technology realize screen pixels and obtain.For high performance server, by the characteristic of specific video card, by driving layer to control video memory data.
Fast video coding.After the data acquisition of video memory arrives, common server is by Intel MediaSDK(Intel media software exploitation cover) complete the coding of data.If high definition server, the coding of data is set by driving by being mounted in high-performance video card on server.Coded format is H264.H264 is the high compression digital video coding-coding device standard that the joint video team (JVT, Joint Video Team) that constituted jointly by ITU-T Video coding expert group (VCEG) and ISO/IEC dynamic image expert group (MPEG) proposes.
The application of selecting according to user is offered the corresponding desktop of user by stream media distribution server cluster, and this desktop derives from the data that streaming media server sends in real time; H264 after coding issues user by streaming media server.Streaming media server adopts Darwin's server after optimizing.Support RTSP(Real Time Streaming Protocol, real time streaming transport protocol) spread and put.
Stream media distribution server cluster is mainly responsible for virtual machine desktop Data dissemination to user, after second step, streaming media server will be received the coded data of the original H264 that virtual machine sends in real time endlessly, the real-time desktop data that these data are virtual machine.
(4) user receives the demonstration of decoding after real time data.
(5) user sends to control command in virtual machine by control channel.
(6) control command is directly issued after virtual machine by control channel, and virtual machine generation corresponding actions is carried out the coding of next frame data.
(7) the next frame decoding data that terminal receives after the coding of stream media distribution server cluster distribution shows.
The action of user side directly sends to server by control channel, and server responds corresponding action by coding, as a series of message such as mouse unit, double-click, movement, buttons.
(8) user's data storage writes corresponding position by data storage server simultaneously.
The present invention is based on cloud computing realizes.Whole system is a system based on cloud computing, and cloud computing is based on distributed system architecture of Hadoop() framework and realize.
Virtual employing of the present invention Virtual Machine Model as shown in Figure 4.
Virtual machine directly distributes physics I/O equipment to virtual machine, under this model, the driver of virtual machine inside directly and hardware device direct communication, only needs through on a small quantity, or without VMM(Virtual Machine Manager, virtual machine manager program) management.For the robustness of system; need the virtual support of hardware; use only to the virtual machine of specifying with isolation and protection hardware resource; hardware also needs to possess multiple I/O container subregions simultaneously to be come simultaneously for multiple virtual machine service, and this model has almost been eliminated the demand of moving driver in VMM completely.For example CPU, although CPU is not the I/O equipment of ordinary meaning---and but it is exactly to distribute in this way virtual machine really, and the resource of CPU is also under the management of VMM certainly.
Backstage is by Xen(open source code virtual machine monitor) increase income and revise support hardware virtual, as high performance video card directly obtains actual video card equipment by video card itself virtual on virtual machine.Greatly improve the ability of the processing video image of virtual machine.
The server resource of whole system derives from the performance application server cluster that is deployed in backstage.Application server is divided into multiple, as the common server cluster showing for ordinary desktop, for the high definition game server cluster of high definition game, for the 3D server cluster of 3D special efficacy etc.
On application server, move virtual machine and cloud computing related software, be mainly responsible for the response of the obtaining of support, high speed screen of system, fast coding and control command.Owing to taking as above technology, significantly improve performance and the response speed of whole system.
Adopted in this invention based on cloud computing realize remote dummy desktop show system and method, there is following beneficial effect:
(1) this patent is mainly realized desktop unification and resource-sharing by being deployed in the software in high in the clouds, and by the software in high in the clouds, transfer to backstage high-performance server to complete the work such as playing up of all calculating, storage, picture, the software built-in by server carries out the data after playing up and calculating after high performance Video coding, to send by network.Like this, various terminals (as Android mobile phone, PAD, IPTV, intelligent television etc.) only need to have basic decoding display capabilities and just can know from experience various system applies.
(2) the present invention can increase substantially resource utilization, can allow user experience significantly improve by the coding of the low delay of high-performance.Adopt to concentrate and dispose, reduce and safeguard.Adopt centralized stores, increase safety.
(3) the present invention can be applied to and need to carry out enterprise or the operator of software resource centralized management, the enterprise that cloud computing or virtual demonstration service need to be externally provided or operator, the service provider that need to improve bandwidth availability ratio, cloud desktop services and provide, wander about that play operation provides or cloud storage is applied, and scope is widely used.
In this specification, the present invention is described with reference to its specific embodiment.But, still can make various modifications and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
