Distributed resource model
A distributed resource model is described that maintains traits of resources in a distributed computing system. The traits include properties, commands, and events that, along with protocols operating in the distributed computing system, provide real-time access to the traits of resources in the distributed computing system, as well as real-time command of controls for the resources. Controllers manage and publish the traits of resources and provide various types of functionality, such as arbitration, complexity management, fan-out of capabilities, coordination, adaptation, and resource proxying.
1. A method to distribute traits of a resource by a controller at a host device resource in a home area network, the method comprising:
subscribing to a trait of the resource included in the home area network, by the controller at the host device resource;
receiving, from the resource, properties of the subscribed trait;
based on the receiving the properties of the trait, modifying a controller trait; and
publishing the controller trait.
2. The method of claim 1 , further comprising:
in response to the publishing the controller trait, receiving, by the controller, a command for the controller; and
publishing an other command based on the received command for the controller, the other command being a command of the resource.
3. The method of claim 2 , wherein the resource subscribes to the other command of the controller, and wherein the subscription to the other command enables the resource to receive the other command from the controller.
4. The method of claim 1 , wherein the controller trait includes the trait of the resource and an additional trait of the resource.
5. The method of claim 1 , wherein the controller trait includes the properties of the subscribed trait and a property of the controller.
6. The method of claim 1 , wherein the resource is a device that sleeps periodically, wherein the device does not communicate in the home area network during the sleep periods, and wherein the controller responds on behalf of the resource during the sleep periods.
7. The method of claim 1 , wherein the host device resource is a mesh network device, a hub device, or a border router.
8. An electronic device implemented as a hub device, the electronic device comprising:
a mesh network interface for communication in a home area network; and
a memory and processing system to implement an application for a controller that is configured to:
subscribe to a trait of a resource included in the home area network;
receive, from the resource, properties of the subscribed trait;
based on the received properties of the trait, modify a controller trait; and
publish the controller trait.
9. The electronic device of claim 8 , wherein the controller application is configured to:
in response to the publication of the controller trait, receive a command for the controller; and
publish an other control command based on the received command for the controller, the other control command being a command of the resource.
10. The electronic device of claim 9 , wherein the resource subscribes to the other command of the controller, and wherein the subscription to the other command enables the resource to receive the other command from the controller.
11. The electronic device of claim 8 , wherein the controller trait includes the trait of the resource and properties of the controller.
12. The electronic device of claim 8 , wherein the hub device is a mesh network router, a border router, a smart thermostat, or a security hub.
13. The electronic device of claim 8 , wherein the controller application is configured to:
advertise that the hub device is capable of hosting the controller for the trait of a resource; and
instantiate the controller for the trait of the resource.
14. The electronic device of claim 8 , wherein the controller trait includes the properties of the subscribed trait and a property of the controller.
15. The electronic device of claim 8 , wherein the resource is a device that sleeps periodically, wherein the device does not communicate in the home area network during the sleep periods, and wherein the controller responds on behalf of the resource during the sleep periods.
16. A non-transitory computer-readable storage medium comprising instructions for a controller at a hub, the instructions executable by one or more processors, to configure the hub to:
subscribe to a trait of a resource included in a home area network;
receive, from the resource, properties of the subscribed trait;
based on the received properties of the trait, modify a controller trait; and
publish the controller trait.
17. The non-transitory computer-readable storage medium of claim 16 , the instructions further executable to configure the hub to:
advertise that the hub is capable of hosting the controller for the trait of a resource; and
instantiate the controller for the trait of the resource.
18. The non-transitory computer-readable storage medium of claim 16 , the instructions further executable to configure the hub to:
in response to the publication of the controller trait, receive a command for the controller; and
publish an other control command based on the received command for the controller, the other control command being a command of the resource.
19. The non-transitory computer-readable storage medium of claim 18 , wherein the resource subscribes to the other command of the controller, and wherein the subscription to the other command enables the resource to receive the other command from the controller.
20. The non-transitory computer-readable storage medium of claim 16 , wherein the controller trait includes the properties of the subscribed trait and a property of the controller.
