Performance enhancement in virtual desktop infrastructure (VDI)
View Patent ↗In one embodiment, a method displays images from a remote desktop of a desktop GUI on a client device. The method receives a plurality of image blocks for a frame update of an image of the desktop GUI being displayed on the client device. The remote desktop is being run on a host. The client device determines that one or more missing image blocks have not been received for the frame update and determines if the frame update should be performed without the one or more missing image blocks. If the frame update of the desktop GUI should be performed without the one or more missing image blocks, the client device performs the frame update of the desktop GUI using the plurality of image blocks without using the one or more missing image blocks.

determining whether amount of the missing image information is below a threshold; and
rendering the frame update without the missing image information if the amount of the missing information is below the threshold.
6. The computing device of claim 5 , wherein determining whether the frame update corresponds to the sequence of frames of the fleeting duration further comprises:
pausing the rendering of the frame update and requesting the missing image information from the remote host server if the amount of the missing information is above the threshold.
7. The computing device of claim 1 , wherein determining whether the frame update corresponds to the sequence of frames of the fleeting duration further comprises:
determining that the frame update is part of a sequence of high frequency screen updates wherein a frame that is to be updated by the frame update is likely to be replaced by a subsequent frame update within a predetermined period of time.
8. A computer implemented method for performing a frame update of a graphical user interface (GUI), the method comprising:
receiving, over a network from a remote host server, a plurality of packets containing image information for the frame update of the graphical user interface (GUI) to be displayed by a client device;
detecting that one or more packets in the plurality of packets were lost during transmission of the plurality of packets from the remote host server;
determining whether the frame update corresponds to a sequence of frames of a fleeting duration; and
in response to determining that the frame update corresponds to the sequence of frames of the fleeting duration, rendering the frame update that is missing at least a portion of the image information contained in the one or more packets that were lost during the transmission.
9. The computer implemented method of claim 8 , wherein rendering the frame update that is missing at least a portion of the image information contained in the one or more packets that were lost further comprises at least one of:
extrapolating the missing image information from the received image information contained in the received plurality of packets;
inserting image information into the frame update to reduce noticeability of the missing image information; or
leaving image information from a previous frame unchanged during the frame update.
10. The computer implemented method of claim 8 , wherein detecting that the one or more packets were lost further comprises:
waiting for a predetermined period of time to determine whether the one or more packets were delayed or lost; and
determining that the one or more packets were lost after the predetermined period of time has passed.
11. The computer implemented method of claim 8 , wherein detecting that the one or more packets were lost further comprises:
reading one or more sequence identifiers contained in the plurality of packets; and
determining that the one or more packets were lost based on the sequence identifiers.
12. The computer implemented method of claim 8 , wherein render the frame update that is missing at least a portion of the image information further comprises:
determining whether amount of the missing image information is below a threshold; and
rendering the frame update without the missing image information if the amount of the missing information is below the threshold.
13. The computer implemented method of claim 12 , wherein determining whether the frame update corresponds to the sequence of frames of the fleeting duration further comprises:
pausing the rendering of the frame update and requesting the missing image information from the remote host server if the amount of the missing information is above the threshold.
14. The computer implemented method of claim 8 , wherein determining whether the frame update corresponds to the sequence of frames of the fleeting duration further comprises:
determining that the frame update is part of a sequence of high frequency screen updates wherein a frame that is to be updated by the frame update is likely to be replaced by a subsequent frame update within a predetermined period of time.
15. A non-transitory computer readable storage medium storing a set of instructions executed by one or more processors to cause the one or more processors to perform a set of operations, comprising:
receiving, over a network from a remote host server, a plurality of packets containing image information for the frame update of the graphical user interface (GUI) to be displayed by a client device;
detecting that one or more packets in the plurality of packets were lost during transmission of the plurality of packets from the remote host server;
determining whether the frame update corresponds to a sequence of frames of a fleeting duration; and
in response to determining that the frame update corresponds to the sequence of frames of the fleeting duration, rendering the frame update that is missing at least a portion of the image information contained in the one or more packets that were lost during the transmission.
16. The non-transitory computer readable storage medium of claim 15 , wherein rendering the frame update that is missing at least a portion of the image information contained in the one or more packets that were lost further comprises at least one of:
