Abstract

Systems and methods for increasing robustness of a system with a remote server are provided. Some methods can include a first system remotely controlling a second system, detecting a failure in the first system or in a communication link between the first system and the second system, and temporarily removing control of the second system from the first system.

First claim

What is claimed is:

1. A method comprising: a first system of a first type remotely controlling a second system of a second type by controlling or retrieving data from the second system or by making control or processing decisions for the second system, the first type being different from the second type; the second system detecting a failure in the first system or in a communication link between the first system and the second system; and the second system temporarily removing control of the second system from the first system, wherein temporarily removing control of the second system from the first system includes: copying control logic in the first system to the second system; and enabling a copy of the control logic in the second system to locally control the second system.

2. The method of claim 1 wherein the first system remotely controlling the second system includes the first system executing control logic for the second system.

3. The method of claim 1 wherein detecting the failure in the first system or in the communication between the first system and the second system includes detecting a lack of communication from the first system for a predetermined period of time.

4. The method of claim 1 wherein temporarily removing control of the second system from the first system includes:
providing fallback logic in the second system; and
enabling the fallback logic in the second system to locally control the second system.

5. The method of claim 1 wherein temporarily removing control of the second system from the first system includes:
providing a peripheral device in the second system;
providing fallback logic in the peripheral device; and
enabling the fallback logic in the peripheral device to control the peripheral device.

6. The method of claim 1 further comprising the first system providing a notification of the failure in the first system or in the communication link between the first system and the second system.

7. The method of claim 1 wherein temporarily removing control of the second system from the first system includes:
the second system receiving input;
caching the received input during the failure in the first system or in the communication link between the first system and the second system; and
upon a reconnection between the first system and the second system, the second system transmitting the cached input to the first system.

8. The method of claim 1 further comprising:
providing a secondary device with an internal processing unit; and
enabling the internal processing unit to replace at least some functions executed by the first system.

9. The method of claim 1 wherein temporarily removing control of the second system from the first system includes enabling a differential data exchange between the first system and the second system.

10. The method of claim 9 wherein enabling the differential data exchange between the first system and the second system includes transmitting only changes in a state of data between the first system and the second system.

11. The method of claim 1 wherein temporarily removing control of the second system from the first system includes the second system caching user interface input.

12. The method of claim 1 wherein temporarily removing control of the second system from the first system includes:
providing a backup communication path between the first system and the second system; and
the first system communicating with the second system via the backup communication path.

13. The method of claim 12 wherein a first technology supports the communication link, wherein a second technology supports the backup communication path, and wherein the first technology is dissimilar from the second technology.

14. The method of claim 1 wherein temporarily removing control of the second system from the first system includes:
providing a backup first system with backup control logic, the backup control logic being a duplicate of control logic in the first system; and
enabling the backup control logic in the backup first system to control the second system.

15. A system comprising:
a first system of a first type;
a second system of a second type remotely located from the first system, the first type being different from the second type; and
a communication link connecting the first system and the second system,
wherein the first system executes control logic to remotely control the second system by controlling or retrieving data from the second system or by making control or processing decisions for the second system,
wherein, upon the second system detecting a failure in the first system or in the communication link, the second system temporarily removes control of the second system from the first system,
wherein the second system includes a copy of the control logic in the first system copied from the first system, and
wherein, upon the failure in the first system or in the communication link, the second system enables the copy of the control logic in the second system to locally control the second system.

16. The system of claim 15 wherein the second system includes fallback logic, and wherein, upon the failure in the first system or in the communication link, the second system enables the fallback logic in the second system to locally control the second system.

17. The system of claim 15 further comprising a backup communication path connecting the first system and the second system, wherein, upon the failure in the first system or in the communication link, the first system communicates with the second system via the backup communication path.

18. The system of claim 15 further comprising a backup first system, wherein the backup first system includes backup control logic, the backup control logic being a duplicate of the control logic in the first system, and wherein, upon the failure in the first system or in the communication link, the backup control logic is enabled to control the second system.
