As shown in Figure 1, the virtual desktop system 1 of the specific cloud system and so on of such as enterprise comprises server 11 and at least one terminal device 12.Such as, in virtual desktop system 1, server 11 is connected with terminal device 12 by network wired or wireless arbitrarily.Particularly, when the dedicated network (e.g., LAN) that terminal device 12 is positioned at enterprise is interior, terminal device 12 is connected with server 11 by dedicated network.In addition, time outside the dedicated network that terminal device 12 is positioned at enterprise, terminal device 12 can access the dedicated network of enterprise by the external network of internet and so on, to be connected with server 11.Because above-mentioned connected mode is known to those skilled in the art, be therefore omitted here the description configured with the connection of server 11 about terminal device 12.In addition, according to embodiments of the invention, server 11 stores the multiple virtual desktop agreement of such as standard RDP, expansion RDP, IC standard A agreement or expansion ICA agreement and so on.

According to exemplary embodiment of the present invention, server 11 can comprise the high-performance server of any type, personal computer or work station.

In addition, terminal device 12 can comprise personal computer, notebook, mobile phone, personal digital assistant, thin terminal (thin client) etc.

When user uses terminal device 12 to carry out work or other task, server 11 sets up virtual machine or session on the server for terminal device 12, to provide virtual desktop serve to terminal device 12.Compared with prior art, when providing virtual desktop serve to terminal device 12, server 11 also according to obtaining the information relevant with the type of terminal device 12, and selects the virtual desktop agreement of mating with terminal device 12 from stored multiple virtual desktop agreement according to this information.After have selected the virtual desktop agreement of mating with terminal device 12, server 11 is according to this virtual desktop agreement, process to produce virtual desktop data for the data that terminal device 12 produces to virtual machine or session, and these virtual desktop data are sent to terminal device 12 by server 11.

By above-mentioned configuration, major part process (e.g., task or computing) all completes at server end, and the data produced are sent to terminal device 12.Therefore, user feels all right similarly is that terminal device 12 " in this locality " performs work or task.In this case, when not affecting user's use sense and being subject to, do not need the equipment (e.g., thin terminal) that performance is very high to be used as terminal device 12, thus reduce the cost of whole virtual desktop system 1.In addition, compared with prior art, in virtual desktop system, also select the virtual desktop agreement of mating with terminal device 12 based on the information that the type of terminal device 12 is relevant, and utilize this virtual desktop agreement to produce the virtual desktop data being applicable to this terminal device 12.Like this, virtual desktop system 1 can support the terminal device 12 of number of different types, and can provide the virtual desktop data of the disposal ability being applicable to this terminal device neatly based on the type of terminal device 12 or performance.

Below by the operation performed by the structure of the server 11 shown in detailed description Fig. 1 and server 11.Fig. 2 is the schematic block diagram of the structure of the server 11 shown in schematic thinking 1.

As shown in Figure 2, server 11 comprises interface unit 111, memory cell 112 and processing unit 113.Interface unit 111 and memory cell 112 are connected with processing unit 113.

According to one embodiment of present invention, interface unit 111 can be made up of arbitrary wired or wireless interface or communication module.Such as, interface unit 111 can be lan interfaces, wireless module etc.Here, interface unit 111 for setting up the connection with terminal device 12, and can send data to terminal device 12, and can receive data from terminal device 12.

Memory cell 112 can be made up of the nonvolatile memory of such as hard disk, solid state hard disc, storage card and so on, and for storing multiple virtual desktop agreement.Here, such as, virtual desktop agreement comprises at least one (will be discussed in more detail below) in standard RDP, expansion RDP, IC standard A agreement or expansion ICA agreement, PCoIP agreement.

Processing unit 113 can be made up of central processing unit (CPU), microprocessor, DSP etc., and can set up virtual machine or session according to the request of terminal device 12, thus provides virtual desktop serve to terminal device 12.

In addition, according to embodiments of the invention, processing unit 113 can also obtain the information relevant with the type of terminal device 12, and from multiple virtual desktop agreement, select the virtual desktop agreement of mating with terminal device 12 according to this information.Then, processing unit 12 is based on selected virtual desktop agreement, session or described virtual machine are processed to produce the virtual desktop data being applicable to terminal device 12 for the data that terminal device 12 produces, and by interface unit 111, these virtual desktop data can be sent to terminal device 12.

There is provided according to the server 11 of the embodiment of the present invention operation performed during virtual desktop serve to terminal device 12 below by detailed description.

According to embodiments of the invention, when user uses terminal device 12 to use virtual desktop serve, terminal device 12 establishes a communications link to server 11 request, and sets up the communication connection of terminal device 12 and server 11 based on the request of terminal device 12.Particularly, when terminal device 12 (e.g., thin terminal, personal computer, notebook etc.) is positioned at the dedicated network of company, terminal device 12 directly can set up the communication connection with server 11.In addition, when the dedicated network that terminal device 12 is positioned at company is outer, terminal device 12 can set up the communication connection with server 11 by using VPN (VPN) software via the dedicated network of internet and company, and can by open server 11 predetermined port (as, 80 ports) and predetermined service function (e.g., the direct access function of Microsoft) realize the communication connection of terminal device 12 and server 11.Because the configuration of above-mentioned communication connection and process are known to those skilled in the art, be therefore omitted here their detailed description.

After the communication connection of setting up terminal device 12 and server 11, the processing unit 113 of server 11, based on the request of terminal device 12, sets up virtual machine or session for terminal device 12.

Particularly, when setting up session for terminal device 12, the memory cell 112 of server 11 stores the user profile corresponding with the user of terminal device 12 usually, and when setting up session according to the request of terminal device 12, set up the session corresponding with terminal device 12 based on user profile.Such as, in the operating system of server 11 (e.g., Windows Server 2008), multiple session can be set up for multiple terminal device 12 and provide virtual desktop serve to multiple terminal device 12.Because the many underlying operating system processes in the operating system of server 11 are shared by multiple terminal device 12, the expense therefore setting up multiple session in the operating system of server 11 is lower.But because the user of multiple terminal device 12 shares an operating system, therefore the application of multiple user is installed in this operating system, thus operating system may be caused to become too fat to move.

In addition, based on the configuration of server 11, virtual machine can also be set up for terminal device 12.In this case, the memory cell 112 of server 11 stores the image file corresponding with the user of terminal device 12 usually, and when setting up session according to the request of terminal device 12, set up the virtual machine corresponding with terminal device 12 based on user profile.Server 11 can be set up multiple virtual machine for multiple terminal device 12 and provide virtual desktop serve to multiple terminal device 12.In this case, each virtual machine on server 11 runs a complete operating system independently, and the system supervisor (Hypervisor) according to configuration on server 11 distributes the server resource shared by each virtual machine (e.g., CPU/RAM resource).The usual expense of virtual machine mode is very large, and therefore server 11 can not support too much terminal device 12 (user).

When server 11 sets up virtual machine for terminal device 12, because each virtual machine on server 11 runs a complete operating system independently, be therefore equivalent to run multiple complete operating system on the server 11 simultaneously.In this case, because each operating system can also set up session for different terminal devices 12, therefore each virtual machine can also set up session for different terminal devices 12.Such as, as required multiple terminal device 12 can be divided into many groups, each group comprises at least one terminal device 12, and wherein server 11 sets up multiple virtual machine for many group terminal devices 12, and sets up at least one session at least one terminal device 12 in group in virtual machine.

Session is used to be with the advantage of the mixed architecture of virtual machine: with set up the pattern of independently virtual machine for terminal device 12 compared with, the quantity of virtual machine greatly reduces, thus decrease taking system resource, and server 11 can support more user.In addition, with set up the pattern of independently virtual machine for terminal device 12 compared with, can only for set up applications on the virtual machine often organizing user, thus avoid and in an operating system, multiple utility program was installed and the situation causing operating system too too fat to move.Therefore, according to above-mentioned configuration, the mixed architecture setting up session and virtual machine for terminal device 12 can utilize the limited system resources of server 11 as much as possible for terminal device 12 provides virtual desktop serve.

After the processing unit 113 of server 11 sets up virtual machine or session for terminal device 12, virtual machine on server 11 or session based on the user of terminal device 12 operation (as, opening document, invokes application etc.) carry out predetermined process, and produce result.Here, because the virtual machine set up for the user of terminal device 12 or session may need to call or run application, therefore various application program can also be stored in server 11.In addition, server 11 can also be connected to obtain various application program from application server when needed with the application server (not shown) storing application program specially.The run duration of virtual machine or session is being set up for terminal device 12, the processing unit 113 of server 11 carries out predetermined process to produce virtual desktop data based on predetermined virtual desktop agreement to the result that virtual machine or session produce, and these virtual desktop data are sent to terminal device 12.Therefore, although the major part process performed based on the operation of the user of terminal device 12 (as, computing) all carry out at server end, but because virtual desktop data are sent to terminal device 12, therefore user sensuously remains and processes the operation of user or the task of distribution by terminal device 12 " in this locality ".

How specific descriptions server 11 is selected virtual desktop agreement below, and produce the process of virtual desktop data based on predetermined virtual desktop agreement.

Particularly, during the communication connection of setting up terminal device 12 and server 11, or before server 11 will start to process for the data that terminal device 12 produces virtual machine or session based on predetermined virtual desktop agreement, the processing unit 113 of server 11 can send request for obtaining the information relevant with the type of terminal device 12 by interface unit 111 to terminal device 12, and terminal device 12 sends the information relevant with its type according to the request from server 11 to server 11.Such as, the information relevant with the type of terminal device 12 can include, but is not limited to terminal device 12 graphics capability (as, 2D/3D acceleration capacity), the hardware decode performance of terminal device (as, image or video decode performance), at least one in the central processing unit performance (e.g., CPU frequency) of terminal, the virtual desktop protocol type of terminal device support and the operating system supported.

After the processing unit 113 of server 11 obtains the information relevant with the type of terminal device 12, processing unit 113, based on the information relevant with the type of terminal device 12, selects the virtual desktop agreement being applicable to terminal device 12 from the multiple virtual desktop agreement being stored in memory cell 112.Here, multiple virtual desktop agreement comprises at least one in (but being not limited to) standard RDP, expansion RDP, IC standard A agreement or expansion ICA agreement and PCoIP agreement.

Particularly, processing unit 113 is with reference to the information relevant with the type of terminal device 12, and namely processing unit 113 determines any virtual desktop agreement being used as being applicable to terminal device 12 of selecting in multiple virtual desktop agreement with reference to information such as the hardware decode performance of the graphics capability of terminal device 12, terminal device, the central processing unit performance of terminal, the virtual desktop protocol type of terminal device support and the operating systems supported.

Such as, when processing unit 113 is by referring to the information relevant with the type of terminal device 12, learn terminal device 12 have very strong hardware graphics disposal ability (as, there is personal computer or the notebook of display card) time, processing unit 113 RDP of choice criteria or the ICA agreement of standard can process data that session or virtual machine produce for terminal device 12 to produce virtual desktop data, and these virtual desktop data are sent to terminal device 12.According to the specification of RDP or ICA agreement, standard RDP or ICA agreement do not process in a large number to the data that session or described virtual machine produce.That is, the primitive data (original desktop data) that session or described virtual machine produce is sent to terminal device 12 by interface unit 111 based on standard RDP or ICA agreement by processing unit.In this case, because terminal device 12 needs the primitive data produced session or described virtual machine to carry out the predetermined process of such as graphics process and so on to produce the view data that will be presented on terminal device 12, therefore data produced based on standard RDP or the session of ICA protocol processes or described virtual machine at the processing unit 113 of server 11 when sending it to terminal device 12, need terminal device 12 possess certain graphics capability to produce to be presented at image on terminal device 12 (as, desktop, video image, Application Program Interface, game picture etc.).Therefore, at processing unit 113 by referring to the information relevant with the type of terminal device 12, when learning that terminal device 12 has very strong hardware graphics disposal ability, processing unit 113 adopts standard RDP or ICA agreement to be used as being applicable to the virtual desktop agreement of terminal device 12.

In addition, such as, when processing unit 113 is by referring to the information relevant with the type of terminal device 12, when learning that the central processing unit performance of terminal device 12 is very strong, processing unit 113 also can the RDP of choice criteria or the ICA agreement of standard process data that session or described virtual machine produce for terminal device 12 with produce virtual desktop data (as, primitive data), and based on above-mentioned agreement, these virtual desktop data are sent to terminal device 12.This is because the central processing unit performance of terminal device 12 is very strong, therefore terminal device 12 can utilize central processing unit, in pure software mode, predetermined graphics process is carried out to produce the image (e.g., desktop) that will be presented on terminal device 12 to the data sent from server 11.In this case, the processing unit 113 of server 11 also can adopt standard RDP or ICA agreement to be used as being applicable to the virtual desktop agreement of terminal device 12.

In addition, at processing unit 113 by referring to the information relevant with the type of terminal device 12, when learning that terminal device 12 does not possess very strong GPU or central processing unit, or terminal device 12 have stronger image decoding unit (as, Video Decoder) when, because terminal device 12 is comparatively slow to primitive data process by its performance limit, therefore cause to show image (e.g., desktop) in real time on terminal device 12.In this case, processing unit 113 can select to expand RDP or expansion ICA agreement to the data processing session or described virtual machine and produce for terminal device 12 to produce virtual desktop data, and based on above-mentioned agreement, these virtual desktop data is sent to terminal device 12.

Here, it should be noted that, according to the specification of RDP or ICA agreement, in RDP or I CA agreement, reserved multiple passage, and allow user to carry out self-defined to multiple passages reserved in RDP or ICA agreement.Therefore, the self-defined customized extension RDP of coming or ICA agreement can be carried out to support the data content that customizes and form to multiple passages reserved in RDP or ICA agreement as required.Such as, multiple passages reserved in RDP or ICA agreement carry out self-defined come after customized extension RDP or ICA agreement, the data with custom formats can be transmitted in the self-defining data channel of expansion RDP or ICA agreement, and not transmit data in former data channel in expansion RDP or ICA agreement.In addition, the data of the form of customization can also be transmitted in the self-defining data channel of expansion RDP or ICA agreement, and transmit remaining data in former data channel in expansion RDP or ICA agreement.

Particularly, such as, at processing unit 113 by referring to the information relevant with the type of terminal device 12, learn that terminal device 12 does not possess very strong graphics capability, but have stronger hardware video or image decoding ability (as, there is hardware video decoder module) time, processing unit 113 can select expansion RDP or expansion ICA agreement, process the data of session or virtual machine generation to produce virtual desktop data based on determined expansion RDP or expansion ICA agreement, and based on above-mentioned agreement, these virtual desktop data are sent to terminal device 12.In this case, the data that session or virtual machine produce based on determined expansion RDP or expansion ICA agreement, can be converted to data bitmap (virtual desktop data) according to (such as) JPEG/MPEG or self-defining algorithm by processing unit 113.Then, produced data bitmap (virtual desktop data) is sent to terminal device 12 by interface unit 111 based on above-mentioned agreement by processing unit 113.Now, because terminal device 12 has stronger hardware video or image decoding ability, even if the therefore graphics capability of terminal device 12 or the poor-performing of central processing unit, terminal device 12 also can be decoded to the data bitmap that server 11 sends glibly, and the image (e.g., desktop) that will show on terminal device 12 is produced based on this data bitmap.

In addition, the present invention is not limited thereto, at processing unit 113 by referring to the information relevant with the type of terminal device 12, learn that terminal device 12 has certain graphics capability, and when having stronger hardware video or image decoding ability, processing unit 113 can select the expansion RDP or the expansion ICA agreement that are applicable to this terminal device 12.In this case, processing unit 113 can based on determined expansion RDP or expansion ICA agreement, according to (such as) JPEG/MPEG or self-defining algorithm, a part of data that session or virtual machine produce are converted to data bitmap (virtual desktop data), and retain a part of primitive data (remaining virtual desktop data).Then, produced data bitmap (virtual desktop data) and remaining primitive data (remaining virtual desktop data), based on determined expansion RDP or ICA agreement, are sent to terminal device 12 by interface unit 111 by processing unit 113.Now, due to terminal device 12, there is stronger hardware video or image decoding ability and there is certain graphics capability, therefore terminal device 12 can be decoded to the data bitmap from server 11 by hardware decode module, and the primitive data from server 11 is processed by GPU or with software mode by CPU, thus the image (e.g., desktop) that will show on terminal device 12 can be produced based on data bitmap and primitive data.

By above-mentioned configuration, in the virtual desktop system 1 of such as cloud system and so on, by obtaining the information relevant with the type of terminal device 12, from multiple virtual desktop agreement, a virtual desktop agreement of mating with terminal device is selected based on this information, and produce based on this virtual desktop agreement and be applicable to this terminal device 12 (namely, with the Performance Match of terminal device 12) virtual desktop data, to show image (e.g., desktop) on terminal device 12.By the way, virtual desktop system 1 can support number of different types terminal device 12 (as, PC, notebook, thin terminal, mobile phone etc.), and the virtual desktop data of the disposal ability being applicable to this terminal device can be provided neatly based on the type of terminal device or performance, thus improve the usage degree of user and experience sense is subject to.
