System and method for managing power of remote and virtual desktops

1. A method for managing power of remote and virtual desktops comprising:

determining, by a processor, a frame rate output from a server of content displayed at a client device;

determining, by the processor, whether the frame rate is greater than a predetermined threshold value;

determining, by the processor, whether the frame rate has remained constant within a predetermined threshold difference for a period of time;

when the frame rate is greater than the predetermined threshold value and when the frame rate has remained constant, activating, by the processor, a poll mode at the client device, wherein in the poll mode the client device polls the server at a frequency specified by the server for updates to the content displayed at the client device, otherwise:

activating, by the processor, a push mode at the client device to preserve power at the server wherein in the push mode the client device sends a request to the server to schedule a refresh of the content displayed at the client device; and

executing, by the processor, reception of content for display at the client device from the server according to the activated mode.

2. The method of claim 1 , further comprising:

determining that the server is inactive; and

activating a poll mode for the client device.

3. The method of claim 2 , wherein the content is video output of operations performed on the server.

4. The method of claim 3 , wherein the operations comprise a remote desktop session hosted by the server, and wherein the server is a guest computer, a remote application server (RAS), or a virtual machine.

5. The method of claim 4 , further comprising:

determining that the poll mode is activated for a predetermined period of time; and

pausing one or more applications executing on the remote desktop session, wherein the server is the remote application server (RAS).

6. The method of claim 4 , wherein the remote desktop session is paused.

7. The method of claim 2 , wherein the server is a guest computer, and the guest computer screen has dimmed.

8. The method of claim 7 , further comprising:

enabling dimming of a display of the guest computer; and

shifting time of a guest dimming event to a nearest predefined moment.

9. The method of claim 1 , wherein the push mode further comprises:

writing frames of the content to a shared memory; and

performing an inter-process communication (IPC) call for server to check and schedule a refresh of a display of the client.

10. The method of claim 1 , wherein the poll mode further comprises:

checking a shared memory at a predetermined frequency; and

refreshing a display of the client if the shared memory has changed.

11. A system for managing power of remote and virtual desktops comprising:

a hardware processor configured to:

determine a frame rate output from a server of content displayed at a client device;

determine whether the frame rate is greater than a predetermined threshold value;

determine whether the frame rate has remained constant within a predetermined threshold difference for a period of time;

when the frame rate is greater than the predetermined threshold value and when the frame rate has remained constant, activate a poll mode at the client device, wherein in the poll mode the client device polls the server at a frequency specified by the server for updates to the content displayed at the client device, otherwise:

activate a push mode at the client device to preserve power at the server wherein in the push mode the client device sends a request to the server to schedule a refresh of the content displayed at the client device; and

execute reception of content for display at the client device from the server according to the activated mode.

12. The system of claim 11 , wherein the hardware processor is further configured to:

determine that the server is inactive; and

activate a poll mode for the client device.

13. The system of claim 12 , wherein the content is video output of operations performed on the server.

14. The system of claim 13 , wherein the operations comprise a remote desktop session hosted by the server, and wherein the server is a guest computer, a remote application server (RAS), or a virtual machine.

15. The system of claim 14 , wherein the hardware processor is further configured to:

determine that the poll mode is activated for a predetermined period of time; and

pause one or more applications executing on the remote desktop session, wherein the server is the remote application server (RAS).

16. The system of claim 14 , wherein the remote desktop session is paused.

17. The system of claim 12 , wherein the server is a guest computer, and the guest computer screen has dimmed.

18. The system of claim 17 , wherein the hardware processor is further configured to:

enable dimming of a display of the guest computer; and

shift time of a guest dimming event to a nearest predefined moment.

19. The system of claim 11 , wherein the push mode further comprises:

write frames of the content to a shared memory; and

perform an inter-process communication (IPC) call for server to check and schedule a refresh of a display of the client.

20. The system of claim 11 , wherein the poll mode further comprises:

checking a shared memory at a predetermined frequency; and

refreshing a display of the client if the shared memory has changed.

21. A non-transitory computer-readable medium, storing instructions thereon for managing power of remote and virtual desktops, the instructions comprising:

determining a frame rate output from a server of content displayed at a client device;

determining whether the frame rate is greater than a predetermined threshold value;

determining whether the frame rate has remained constant within a predetermined threshold difference for a period of time;

when the frame rate is greater than the predetermined threshold value and when the frame rate has remained constant, activating a poll mode at the client device, wherein in the poll mode the client device polls the server at a frequency specified by the server for updates to the content displayed at the client device, otherwise:

activating a push mode at the client device to preserve power at the server wherein in the push mode the client device sends a request to the server to schedule a refresh of the content displayed at the client device; and

executing reception of content for display at the client device from the server according to the activated mode.
