[0052] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0053] See also Figure 1 The following embodiments use the above-mentioned terminal as the execution subject, and apply the method provided by the embodiment of the present disclosure to the terminal for specific description. The method for integrating TCI and VDI virtual desktops provided by the embodiment of the present disclosure includes the following steps 101 to 103:

[0054] Step 101, obtaining a TCI desktop startup instruction, and detecting whether the file version corresponding to the local differential desktop is the latest version on the server side according to the TCI desktop startup instruction;

[0055] In this step, the terminal enters the physical machine operating system Host OS after startup, and after obtaining the user-selected startup TCI desktop instruction, the physical machine operating system Host OS will first check whether the local differential desktop file version is the latest version on the server.

[0056] Step 102: If the file version corresponding to the local differential desktop is the latest version, a current operation differential file is created based on the local differential desktop, and the current operation differential file is loaded into the desktop;

[0057] In this step, if the terminal side and the server side versions are the same, a differential file for this operation is created directly based on the differential desktop, and the file is loaded into the desktop.

[0058] Step 103, obtain the TCI desktop closing instruction, and close the TCI desktop according to the TCI desktop closing instruction, merge the current operation differential file into the local differential desktop file, delete the current operation differential file, and increase the local differential desktop version by 1.

[0059] In this step, after receiving the user's instruction to close the TCI desktop, the TCI agent module triggers the restart of the terminal to enter the physical machine operating system Host OS, and then starts the synchronization of the current running differential file in the physical machine operating system Host OS and merges the local running differential file into the differential desktop file. After the merge is completed, the local running differential file is deleted and the differential desktop file version is increased by 1, and finally the terminal is closed.

[0060] In one embodiment, the method comprises:

[0061] If the file version corresponding to the local differential desktop is not the latest version, comparing the file version corresponding to the local differential desktop with the file version corresponding to the differential desktop on the server side;

[0062] If the file version corresponding to the differential desktop on the server side is newer than the file version corresponding to the local differential desktop, the file version corresponding to the local differential desktop is updated to be the same as the file version corresponding to the differential desktop on the server side.

[0063] In this embodiment, if the file version corresponding to the differential desktop on the server side is newer than the file version corresponding to the local differential desktop, the differential desktop file on the terminal side and the differential desktop file on the server side are compared, and then the differential data is synchronized to the terminal side, and the differential desktop file and version on the terminal side are updated.

[0064] In one embodiment, the method comprises:

[0065] If the file version corresponding to the local differential desktop is newer than the file version corresponding to the differential desktop on the server, obtain the terminal idle instruction sent by the server and the current file version corresponding to the differential desktop on the server;

[0066] The local CPU and the current network load are monitored, and when the local CPU and the current network load are both below a preset threshold, the file version corresponding to the local differential desktop is synchronized to the server.

[0067] In this embodiment, if the file version corresponding to the local differential desktop is newer than the file version corresponding to the differential desktop on the server side, the server notifies the terminal to report the current version of the differential desktop data when it is idle. The terminal enters the desktop according to the process of step 103, and notifies the TCI agent module to monitor the local CPU and network load. If the load meets the requirement of being lower than the threshold, the differential desktop file on the terminal side is compared with the differential desktop file on the server side, and then the differential data is synchronized to the server.

[0068] Optionally, before obtaining the instruction to start the TCI desktop, the method includes:

[0069] The terminal downloads the public image and the local differential desktop from the server; wherein the local differential desktop is created by the server based on the public image.

[0070] In this embodiment, the server creates a public image and creates a personal differential desktop based on the public image. After the fat terminal is initialized, it downloads the public image and the personal differential desktop. If multiple people share the terminal, a public image and a differential desktop for each person are saved. Figure 2 Create chained differentials, so new users only need to download their personal differential desktop when using the terminal for the first time.

[0071] In the method, terminal and server for the integrated use of TCI and VDI virtual desktops provided by the embodiments of the present disclosure, a public unified image is used to chain the establishment of a private desktop personality difference and a temporary data difference, and the server and the terminal jointly process the differential data, thereby realizing the integration of TCI and VDI desktops and supporting TCI desktop roaming, so that the same desktop can be compatible with the advantages of two architecture desktops, allowing users to flexibly choose to use according to their actual needs and scenarios, and switch at any time. At the same time, the remote desktop on the server side only needs to run when the user needs to use the VDI desktop (start as needed), saving overall deployment and operation costs.

[0072] Figure 3 It is a logical diagram of the proximal use of the TCI desktop in a method for integrated use of TCI and VDI virtual desktops provided by an embodiment of the present disclosure.

[0073] See also Figure 4 The following embodiments use the above server as the execution subject, and apply the method provided by the embodiment of the present disclosure to the server for specific description. The method for integrating TCI and VDI virtual desktops provided by the embodiment of the present disclosure includes the following steps 401 to 403:

[0074] Step 401: Receive a VDI desktop connection instruction sent by a target terminal, and detect whether there is a terminal using a cloud desktop locally;

[0075] In this step, the terminal accesses the cloud desktop on the server side, and the server checks whether there is a fat terminal being used locally on the desktop.

[0076] Step 402: If no terminal is using the cloud desktop locally, a current operation differential file is created based on the differential desktop, and the current operation differential file is loaded to start the VDI desktop, and the VDI desktop is returned to the target terminal;

[0077] In this step, if no fat terminal is being used locally, a differential file for this operation is created based on the differential desktop, and the file is loaded to start the desktop, and the VDI desktop is returned to the terminal.

[0078] Step 403: Obtain the VDI desktop closing instruction sent by the target terminal, and close the VDI desktop according to the VDI desktop instruction, merge the current operation differential file into the local differential desktop file, delete the current operation differential file, and increase the local differential desktop version by 1.

[0079] In this step, after receiving the running differential file, the server will also merge the running differential file into the differential desktop file. After the Merge is completed, the running differential file is deleted and the differential desktop file version is increased by 1. That is, when the user ends the desktop use, the terminal notifies the server to close the desktop. The server closes the desktop and merges the running differential file into the differential desktop file. After the Merge is completed, the running differential file is deleted and the differential desktop file version is increased by 1.

[0080] In one embodiment, the method further comprises:

[0081] If a terminal is using the cloud desktop locally, a request message is sent to the terminal currently in use, wherein the request message is used to request the terminal currently in use to release the cloud desktop and synchronize data;

[0082] Instruct the currently used terminal to close the cloud desktop according to the request information, start the synchronization processing of the differential file of this operation, merge the differential file of this operation into the local differential desktop file, delete the differential file of this operation, and increase the local differential desktop version by 1.

[0083] In this embodiment, if a fat terminal is being used locally (the policy allows the use right to be preempted by default, and if not, the desktop connection is denied), the server requests the terminal being used locally to release the desktop and synchronize data.

[0084] After receiving the request, the terminal shuts down the desktop first, then starts the synchronization of the differential file for this operation. After the synchronization is completed, the local differential file is merged into the differential desktop file. After the merge is completed, the local differential file is deleted and the differential desktop file version is increased by 1.
