Abstract

Systems and methods relating to communication within a fabric network are presented. The fabric network includes one or more logical networks that enables devices connected to the fabric to communicate with each other using various profiles known to the devices. A device sending a message may follow a general message format to encode the message so that other devices in the fabric may understand the message regardless of which logical networks the devices are connected to. Within the message format, a payload of data may be included for the receiving device to forward, store, or process the message. The format and the contents of the payload may vary according to a header within the payload that indicates a profile and a message type within the profile. Using the profile and message type, the receiving devices may decode the message to process the message.

Claims

1. An electronic device configured to communicate on a fabric network comprising multiple devices in a home environment, the fabric network comprising multiple logical networks, the electronic device configured to:

generate a message for transmission to another device of the multiple devices in the fabric network, the message including an address of the other device; and

transmit the generated message to a cloud service over a platform layer in the fabric network, the transmission being effective to cause the cloud service to use the address to forward the message to the other device, the electronic device being configured to communicate in a first network of the fabric network using a first communication protocol and the other device being configured to communicate in a second network of the fabric network using a second communication protocol.

2. The electronic device of claim 1, wherein the first network is a Wi-Fi network and the second network is an IEEE 802.15.4 network.

3. The electronic device of claim 2, wherein the message is transmitted via a Wi-Fi router in the first network.

4. The electronic device of claim 1, wherein the other device is one of:

a consumer device, a cloud server, a hazard detector, a security device, a thermostat, or a camera.

5. The electronic device of claim 1, wherein the generated message includes a fabric identifier (ID), the fabric ID comprising a global identifier and a subnet identifier.

6. The electronic device of claim 1, wherein the message is transmitted as one or more Internet Protocol version 6 (IPv6) packets.

7. The electronic device of claim 1, wherein the message is transmitted across multiple networks using a Transmission Control Protocol (TCP) or a User Datagram Protocol (UDP).

8. The electronic device of claim 1, wherein the communication between the electronic device and the other device is unidirectional or bidirectional.

9. The electronic device of claim 1, wherein the electronic device is further configured to receive a response to the transmitted message from the other device.

10. A method of communicating by an electronic device on a fabric network comprising multiple devices in a home environment, the fabric network comprising multiple logical networks, the method comprising:

generating, by the electronic device, a message for transmission to another device of the multiple devices in the fabric network, the message including an address of the other device; and

transmitting the generated message to a cloud service over a platform layer in the fabric network, the transmitting being effective to cause the cloud service to use the address to forward the message to the other device, the electronic device being configured to communicate in a first network of the fabric network using a first communication protocol and the other device being configured to communicate in a second network of the fabric network using a second communication protocol.

11. The method of claim 10, wherein the first network is a Wi-Fi network and the second network is an IEEE 802.15.4 network, and wherein the transmitting the message is via a Wi-Fi router in the first network.

12. The method of claim 10, wherein the generated message includes a fabric identifier (ID), the fabric ID comprising a global identifier and a subnet identifier.

13. The method of claim 10, wherein the message is transmitted as one or more Internet Protocol version 6 (IPv6) packets, and wherein the message is transmitted across multiple networks using a Transmission Control Protocol (TCP) or a User Datagram Protocol (UDP).

14. The method of claim 10, further comprising:

in response to the transmitting the generated message, receiving a response to the transmitted message from the other device.

15. The method of claim 10, wherein the other device is one of:

a consumer device, a cloud server, a hazard detector, a security device, a thermostat, or a camera.

16. The method of claim 10, wherein the communication between the electronic device and the other device is unidirectional or bidirectional.

17. A system comprising:

an electronic device configured to communicate on a fabric network comprising multiple devices in a home environment, the fabric network comprising multiple logical networks, the electronic device configured to;

generate a message for transmission to another device of the multiple devices in the fabric network, the message including an address of the other device;

transmit the generated message to a cloud service over a platform layer in the fabric network, the transmission being effective to cause the cloud service to use the address to forward the message to the other device, the electronic device being configured to communicate in a first network of the fabric network using a first communication protocol;

the other device configured to;

receive the generated message; and

in response to the reception of the message, transmit a response to the electronic device, the other device being configured to communicate in a second network of the fabric network using a second communication protocol.

18. The system of claim 17, wherein the generated message includes a fabric identifier (ID), the fabric ID comprising a global identifier and a subnet identifier, wherein the message is transmitted as one or more Internet Protocol version 6 (IPv6) packets, and wherein the message is transmitted across multiple networks using a Transmission Control Protocol (TCP) or a User Datagram Protocol (UDP).

19. The system of claim 17, wherein the other device is one of:

a consumer device, a cloud server, a hazard detector, a security device, a thermostat, or a camera.

20. The system of claim 17, wherein the first network is a Wi-Fi network and the second network is an IEEE 802.15.4 network.
