Abstract

Various systems and methods may be used to implement a software defined industrial system. For example, an orchestrated system of distributed nodes may run an application, including modules implemented on the distributed nodes. The orchestrated system may include an orchestration server, a first node executing a first module, and a second node executing a second module. In response to the second node failing, the second module may be redeployed to a replacement node (e.g., the first node or a different node). The replacement mode may be determined by the first node or another node, for example based on connections to or from the second node.

First claim

What is claimed is:

1. An orchestrated system of distributed nodes running an application, the orchestrated system comprising:
a first node executing a first software component with a first output; and
a second node executing a second software component, the second software component using the first output as an input, and providing a second output to a third software component executing on a third node;
wherein, in response to detection of a failure of the second node, the first node and the third node are configured to coordinate to bypass the second node by using input state information stored at the first node and output state information stored at the third node to run the second software component at the first node or the third node.

2. The orchestrated system of claim 1 , wherein the failure of the second node is an error in the second output.

3. The orchestrated system of claim 1 , wherein the third node includes a redundant second software component preconfigured to replace the second node.

4. The orchestrated system of claim 3 , wherein the redundant second software component is virtualized.

5. The orchestrated system of claim 3 , wherein the third node runs a virtualization of the second node, and wherein the redundant second software component is run in the virtualization of the second node.

6. The orchestrated system of claim 1 , wherein the second node i further configured to send parameters and state information about the second software component, to the third node before the failure.

7. The orchestrated system of claim 1 , wherein in response to the third node failing, a redundant node is designated to replace the third node.

8. The orchestrated system of claim 1 , wherein the first node is configured to save a redundant state of the second software component when the first output is generated.

9. The orchestrated system of claim 1 , wherein when coordinating, the first node and the third node are configured to determine a set of nodes connected to the second node.

10. The orchestrated system of claim 1 , wherein the configuration of the first, second, and third software components on the first, second, and third nodes is initially generated by an orchestration server, and wherein the orchestration server is configured to be disconnected from the first node, the second node, and the third node during operation.

11. The orchestrated system of claim 1 , wherein the first node is selected as a leader node using a leader-election algorithm.

12. The orchestrated system of claim 1 , wherein at least one of the first, second, or third nodes is run as a virtual node.

13. At least one non-transitory machine readable medium including instructions for orchestrating a system of distributed nodes running an application, which when executed by processing circuitry, cause the processing circuitry to:
execute a first software component with a first output at a first node;
execute a second software component at a second node, the second software component to use the first output as an input;
provide a second output, generated using the second software component, to a third software component executing on a third node;
in response to detection of a failure of the second node, bypass the second node, based on coordination between the first node and the third node, using input state information stored at the first node and output state information stored at the third node; and
run the second software component at the first node or the third node based on the coordination.

14. The at least one machine readable medium of claim 13 , wherein the failure of the second node is an error in the second output.

15. The at least one machine readable medium of claim 13 , wherein the third node includes a redundant second software component preconfigured to replace the second node.

16. The at least one machine readable medium of claim 15 , wherein the redundant second software component is virtualized.

17. The at least one machine readable medium of claim 15 , wherein the third node runs a virtualization of the second node, and wherein the redundant second software component is run in the virtualization of the second node.

18. The at least one machine readable medium of claim 13 , wherein the second node is further configured to send parameters and state information about the second software component to the third node before the failure.

19. The at least one machine readable medium of claim 13 , wherein in response to the third node failing, a redundant node is designated to replace the third node.

20. The at least one machine readable medium of claim 13 , wherein the first node is configured to save a redundant state of the second software component when the first output is generated.

21. The at least one machine readable medium of claim 13 , wherein the coordination includes a determination of a set of nodes connected to the second node.

22. The at least one machine readable medium of claim 13 , wherein the configuration of the first, second, and third software components on the first, second, and third nodes is initially generated by an orchestration server, and wherein the orchestration server is configured to be disconnected from the first node, the second node, and the third node during operation.

23. The at least one machine readable medium of claim 13 , wherein the first node is selected as a leader node using a leader-election algorithm.

24. The at least one machine readable medium of claim 13 , wherein at least one of the first, second, or third nodes is run as a virtual node.

25. A method of running an application using distributed nodes of an orchestrated system, the method comprising:
executing a first software component on a first node, the first software component having a first output;
executing a second software component on a second node, the second software component using the first output as an input;
providing a second output from the second software component to a third software component executing on a third node;
in response to detection of a failure of the second node, bypassing the second node, based on coordination between the first node and the third node, using input state information stored at the first node and output state information stored at the third node; and

running the second software component at the first node or the third node based on the coordination.
