Abstract

Provided is a machine-implemented method of operating a device, comprising entering the device into a membership relation with a first self-organizing subnet at a first rank in a hierarchy of subnets of the network; receiving at the device a message from a second device making known parameters of a second subnet at a second rank in the hierarchy of subnets of the network; and responsive to receipt of the message, sending a message from the first device making known parameters of the first subnet at the first rank to the second device to render the subnet at the second rank operable to merge with the subnet at the first rank.

First claim

1 . A machine-implemented method for operating a device, comprising:
entering said device into a membership relation with a first self-organizing subnet at a first rank in a hierarchy of subnets of said network; receiving at said device a message from a second device making known parameters of a second subnet at a second rank in said hierarchy of subnets of said network; and responsive to receipt of said message, sending a message from said first device making known parameters of said first subnet at said first rank to said second device to render said subnet at said second rank operable to merge with said subnet at said first rank.

2 . The machine-implemented method according to claim 1 , said entering said device into a membership relation with a self-organizing subnet comprising attaching said device to a Thread partition of a mesh network.

3 . The machine-implemented method according to claim 1 , said second device making known parameters of said subnet comprising operating according to an advertising protocol of a Thread partition.

4 . The machine-implemented method according to claim 1 , said making known parameters of said subnet at said first rank comprising operating according to an advertising protocol of a Thread partition.

5 . The machine-implemented method according to claim 1 , said hierarchy of subnets being formed from at least a first rank and a second rank, where a subnet at said first rank comprises a leader device having higher-ranking partition information than a leader of a subnet at said second rank.

6 . The machine-implemented method according to claim 1 , said hierarchy of subnets being formed from at least a first rank and a second rank, where a subnet at said first rank has a preponderance of member devices over a subnet at said second rank.

7 . An electronic device comprising logic to:
enter into a membership relation with a first self-organizing subnet at a first rank in a hierarchy of subnets of said network; receive a message from a second device making known parameters of a second subnet at a second rank in said hierarchy of subnets of said network; and responsive to receipt of said message, send a message making known parameters of said first subnet at said first rank to said second device to render said subnet at said second rank operable to merge with said subnet at said first rank.

8 . The electronic device according to claim 7 , said logic to enter said device into a membership relation with a self-organizing subnet comprising logic to attach said device to a Thread partition of a mesh network.

9 . The electronic device according to claim 7 , said second device logic to make known parameters of said subnet comprising logic to operate according to an advertising protocol of a Thread partition.

10 . The electronic device according to claim 7 , said logic to make known parameters of said subnet at said first rank comprising logic to operate according to an advertising protocol of a Thread partition.

11 . The electronic device according to claim 7 , said hierarchy of subnets being formed from at least a first rank and a second rank, where a subnet at said first rank comprises a leader device having higher-ranking partition information than a leader of a subnet at said second rank.

12 . The electronic device according to claim 7 , said hierarchy of subnets being formed from at least a first rank and a second rank, where a subnet at said first rank has a preponderance of member devices over a subnet at said second rank.

13 . A computer program product tangibly embodied in a non-transient computer readable medium having computer readable program code embodied thereon, said computer readable program code being operable, when loaded into a computer and executed thereon, to cause said computer to:
enter into a membership relation with a first self-organizing subnet at a first rank in a hierarchy of subnets of said network; receive a message from a second device making known parameters of a second subnet at a second rank in said hierarchy of subnets of said network; and responsive to receipt of said message, send a message making known parameters of said first subnet at said first rank to said second device to render said subnet at said second rank operable to merge with said subnet at said first rank.

14 . The computer program product according to claim 13 , said entering said device into a membership relation with a self-organizing subnet comprising attaching said device to a Thread partition of a mesh network.

15 . The computer program product according to claim 13 , said second device making known parameters of said subnet comprising operating according to an advertising protocol of a Thread partition.

16 . The computer program product according to claim 13 , said making known parameters of said subnet at said first rank comprising operating according to an advertising protocol of a Thread partition.

17 . The computer program product according to claim 13 , said hierarchy of subnets being formed from at least a first rank and a second rank, where a subnet at said first rank comprises a leader device having higher-ranking partition information than a leader of a subnet at said second rank.

18 . The computer program product according to claim 13 , said hierarchy of subnets being formed from at least a first rank and a second rank, where a subnet at said first rank has a preponderance of member devices over a subnet at said second rank.
