Abstract

In embodiments of mesh network commissioning, a commissioning device of a mesh network can determine steering data for the mesh network, where the steering data is an indication of a device identifier associated with a device that is allowed to join the mesh network. The commissioning device can then propagate the steering data from the commissioning device for the mesh network to one or more routers in the mesh network, and the steering data indicates that a commissioner is active on the mesh network. The commissioning device propagating the steering data enables the one or more routers to transmit the steering data in a beacon message, and the steering data is effective to enable the device associated with the device identifier to identify that the device is allowed to join the mesh network.

Claims

1. A method of identifying devices that are allowed to join a mesh network, the method comprising:

determining steering data for the mesh network, the steering data comprising an indication of a device identifier associated with a device that is allowed to join the mesh network; and

propagating the steering data from a commissioning device for the mesh network to one or more routers in the mesh network, said propagating enabling the one or more routers to transmit the steering data in a beacon message, the steering data effective to enable the device associated with the device identifier to identify that the device is allowed to join the mesh network.

2. The method as recited in claim 1, wherein the steering data comprises a 16 bit Cyclic Redundancy Check (CRC16) of the device identifier.

3. The method as recited in claim 1, wherein the device identifier is an IEEE 64-bit Extended Unique Identifier (EUI-64).

4. The method as recited in claim 1, wherein said determining the steering data for the mesh network further comprises determining the steering data for additional device identifiers associated with additional devices that are allowed to join the mesh network.

5. The method as recited in claim 1, wherein said propagating the steering data is effective to enable the device to distinguish the mesh network from other networks.

6. The method as recited in claim 5, wherein the other networks are IEEE 802.15.4 networks.

7. The method as recited in claim 1, wherein the steering data indicates that a commissioner is active on the mesh network.

8. A mesh network device implemented as a commissioning device, the mesh network device comprising:

a mesh network interface configured for communication in a mesh network;

a memory and processor system to implement a commissioning application that is configured to;

determine steering data for the mesh network, the steering data comprising an indication of a device identifier associated with a device that is allowed to join the mesh network; and

propagate the steering data from a commissioning device for the mesh network to one or more routers in the mesh network, the propagation being enabling the one or more routers to transmit the steering data in a beacon message, the steering data being effective to enable the device associated with the device identifier to identify that the device is allowed to join the mesh network.

9. The mesh network device as recited in claim 8, wherein the steering data comprises a 16 bit Cyclic Redundancy Check (CRC16) of the device identifier.

10. The mesh network device as recited in claim 8, wherein the device identifier is an IEEE 64-bit Extended Unique Identifier (EUI-64).

11. The mesh network device as recited in claim 8, wherein the commissioning application, to determine the steering data for the mesh network, is configured to determine the steering data for additional device identifiers associated with additional devices that are allowed to join the mesh network.

12. The mesh network device as recited in claim 8, wherein the steering data is usable by the device to distinguish the mesh network from other networks.

13. The mesh network device as recited in claim 12, wherein the other networks are IEEE 802.15.4 networks.

14. The mesh network device as recited in claim 8, wherein the steering data indicates that a commissioner is active on the mesh network.

15. A mesh network system, comprising:

a joining device configured to request joining a mesh network; and

a commissioning device of the mesh network, the commissioning device configured to;

determine steering data for the mesh network, the steering data comprising an indication of a device identifier associated with a device that is allowed to join the mesh network; and

propagate the steering data from a commissioning device for the mesh network to one or more routers in the mesh network, the propagation being enabling the one or more routers to transmit the steering data in a beacon message, the steering data being effective to enable the device associated with the device identifier to identify that the device is allowed to join the mesh network.

16. The mesh network system as recited in claim 15, wherein the steering data comprises a 16 bit Cyclic Redundancy Check (CRC16) of the device identifier.

17. The mesh network system as recited in claim 15, wherein the device identifier is an IEEE 64-bit Extended Unique Identifier (EUI-64).

18. The mesh network system as recited in claim 15, wherein the commissioning device, to determine the steering data for the mesh network, is configured to determine the steering data for additional device identifiers associated with additional devices that are allowed to join the mesh network.

19. The mesh network system as recited in claim 15, wherein the steering data enables the device to distinguish the mesh network from other networks.
