Abstract

Various embodiments are described wherein a set of devices are configured to be a logical mesh network. Each device has a logical mesh network address. Further, the set of logical mesh network addresses form a sequence from a first address to a last address, and intermediate addresses having both a preceding and a next address. The devices store forwarding information used to determine how to forward a received logical mesh network packet. Other embodiments are described and claimed.

Claims

1. An apparatus comprising:

logic, at least a portion of which is implemented in hardware or firmware, the logic to comprise a logical connection manager for a first device to manage logical connections with a set of devices, the logical connection manager to comprise;

addressing logic to determine a sequential current logical mesh network (LMN) address in a set of sequential LMN addresses corresponding to the set of devices;

a master interface to connect to a slave interface of a second device within the set of devices, the second device having a sequentially next LMN address; and

a slave interface to connect to a master interface of a third device within the set of devices, the third device having a sequentially previous LMN address.

2. The apparatus of claim 1, the logical connection manager to comprise packet processing logic to determine a destination address of a received LMN packet.

3. The apparatus of claim 2, the packet processing logic to send the received packet to an application layer by a network layer of the first device when the destination address of the received LMN packet is the current LMN address of the first device.

4. The apparatus of claim of claim 3, the packet processing logic to forward the received LMN packet when the destination address is different than the current LMN address of the first device.

5. The apparatus of claim 4, the first device to comprise a host with a power state, the packet processing logic to forward the received LMN packet without causing the power state of the host to change.

6. The apparatus of claim 4, the packet processing logic to forward the received LMN packet based on forwarding information stored in a forwarding information of the first device.

7. The apparatus of claim 6, the forwarding information to comprise an entry for each corresponding device in the set of devices, each entry indexed by the sequential LMN address of the corresponding device.

8. The apparatus of claim 7, the corresponding forwarding information entry to indicate which of the master interface or slave interface of the first device to use to forward the received LMN packet.

9. A non-transitory machine readable storage medium comprising a set of instructions which when executed enable a first device in a set of a devices to:

determine a sequential current logical mesh network (LMN) address in a set of sequential LMN addresses corresponding to the set of devices;

connect by a master interface, to a slave interface of a second device within the set of devices, the second device having a sequentially next LMN address; and

connect by a slave interface, to a master interface of a third device within the set of devices, the third device having a sequentially previous LMN address.

10. The non-transitory machine readable storage medium of claim 9 comprising instructions which when executed enable the first device to determine a destination address of a received LMN packet.

11. The non-transitory machine readable storage medium of claim 10 comprising instructions which when executed enable the first device to send the received packet to an application layer by a network layer of the first device when the destination address of the received LMN packet is the current LMN address of the first device.

12. The non-transitory machine readable storage medium of claim 11 comprising instructions which when executed enable the first device to forward the received LMN packet when the destination address is different than the current LMN address of the first device.

13. The non-transitory machine readable storage medium of claim 12 comprising instructions which when executed enable the first device to forward the received LMN packet without causing a change to a host power state of the first device.

14. The non-transitory machine readable storage medium of claim 12 comprising instructions which when executed enable the first device to forward the received LMN packet based on forwarding information stored in a forwarding information of the first device.

15. The non-transitory machine readable storage medium of claim 14 wherein the forwarding information is to comprise an entry for each corresponding device in the set of devices, each entry indexed by the sequential LMN address of the corresponding device.

16. The non-transitory machine readable storage medium of claim 15 comprising instructions which when executed enable the first device to forward the received LMN packet addressed to the corresponding device with the corresponding indexed sequential LMN address of that entry.

17. A machine-implemented method for a first device in a set of devices, comprising:

determining a sequential current logical mesh network (LMN) address in a set of sequential LMN addresses corresponding to the set of devices;

connecting, by a master interface, to a slave interface of a second device within the set of devices, the second device having a sequentially next LMN address; and

connecting, by a slave interface, to a master interface of a third device within the set of devices, the third device having a sequentially previous LMN address.

18. The machine-implemented method of claim 17 comprising:

determining a destination address of a received LMN packet.

19. The machine-implemented method of claim 18 comprising:

sending the received LMN packet to an application layer by a network layer of the first device when the destination address of the received LMN packet is the current LMN address of the first device.

20. The machine-implemented method of claim 19 comprising:

forwarding the received LMN packet when the destination address is different than the current LMN address of the first device.

21. The machine-implemented method of claim 20 comprising:

forwarding the received LMN packet without causing a change to host power state of the first device.

22. The machine-implemented method of claim 20 comprising:

forwarding the received LMN packet based on forwarding information stored in a forwarding information of the first device.

23. The machine-implemented method of claim 22 wherein the forwarding information is to comprise an entry for each corresponding device in the set of devices, each entry indexed by the sequential LMN address of the corresponding device.

24. The machine-implemented method of claim 23 comprising:

indicating, by the corresponding entry in the forwarding information, which of the master interface or slave interface of the first device to use to forward the received LMN packet.
