Abstract

Redundant links in a network of devices are established. A plurality of devices in the network is configured for communicating data through primary links coupling devices of said plurality of devices. A designated device is configured to receive device data from the plurality of devices. The designated device is further configured to identify a set of devices from the plurality of devices that is operable to establish redundant links in the network. The designated device is further configured to determine configuration data for each device in the set of devices. The designated device is further configured to send the configuration data to the set of devices. The configuration data is operable to establish redundant links for devices in the set of devices in case of a primary link failure.

Claims

1. A system comprising:

a plurality of devices in a network configured for communicating data through primary links coupling devices of the plurality of devices; and

a designated device configured to receive device data from the plurality of devices, wherein the designated device is further configured to identify a set of devices from the plurality of devices that is operable to establish redundant links in the network, wherein the designated device is further configured to determine configuration data for each device in the set of devices, wherein the designated device is further configured to send the configuration data to the set of devices, wherein the configuration data is operable to establish redundant links for devices in the set of devices in case of a primary link failure.

2. The system as described in claim 1, wherein the designated device is further configured to update the set of devices and the associated configuration data in response to a change to the network, wherein the change is an addition of a device to the network or a removal of a device from the network.

3. The system as described in claim 1, wherein the primary link failure causes the set of devices to establish the redundant links for the devices in the set of devices according to the determined configuration data.

4. The system as described in claim 1, wherein the device data comprises device identification, communication capabilities of devices in the plurality of devices, and geolocation of devices in the plurality of devices.

5. The system as described in claim 1, wherein the redundant links are arranged according to a mesh topology.

6. A system comprising:

a plurality of devices forming a communication network, wherein devices of the plurality of devices are networked via their respective primary link; and

a first device of the plurality of devices coupled to a second device of the plurality of device, wherein the first device and the second device are configured to establish a redundant link coupling the first device to the second device to maintain communication between the first device and the second device in presence of a failure associated with communication through the primary link coupling the first device to the second device.

7. The system as described in claim 6 further comprising a designated device configured to determine configuration data for the first and second devices and to send the configuration data to the first and second devices to establish the redundant link responsive to the failure associated with communication through the primary link coupling the first device to the second device.

8. The system as described in claim 6, wherein the first and second devices are further configured to share device data with each other to determine configuration data associated therewith to establish the redundant link responsive to the failure associated with communication through the primary link coupling the first device to the second device.

9. The system as described in claim 8, wherein the device data comprises device identification, communication capabilities of the first and second devices, and geolocation of the first and second devices.

10. The system as described in claim 6 further comprising a third device being added to the communication network, wherein the third device is configured to communicate device data associated therewith with the first device through a primary link of the third device.

11. The system as described in claim 6 further comprising a third device being added to the communication network, wherein the third device is configured to communicate device data associated therewith with the first device through a redundant link of the third device.

12. The system as described in claim 6 further comprising a third device in communication with the first and the second devices, wherein the first device, the second device, and the third device form a set of devices, wherein remaining devices of the formed set of devices maintain communication when one device in the set of devices is removed.

13. The system as described in claim 6, wherein the first device comprises a first communication interface of a first type and a second communication interface of a second type, wherein the second device comprises a first communication interface of the first type and a second communication interface of the second type, wherein the first and second devices communicate through the primary link via their respective first communication interface, and wherein the first and second devices communicate through the redundant link via their respective second communication interface.

14. The system as described in claim 13, wherein the first type is based on a wired link and wherein the second type is based on a wireless link.

15. A system comprising:

a first device comprising a first communicating interface and a second communicating interface; and

a second device comprising a first communicating interface and a second communicating interface, wherein the first communicating interface of the second device is coupled to the first communicating interface of the first device via a primary link, wherein the first device and the second device are configured to communicate respective device data associated therewith with one another, and wherein the respective device data associated therewith is used by the first device and by the second device to configure communication between the first device and the second device through their respective second communicating interface via a redundant link in response to a failure associated with communication via the primary link.

16. The system as described in claim 15, wherein the respective device data associated with the first and second devices are shared between the first and second devices through a broadcast protocol.

17. The system as described in claim 15, wherein the first communication interfaces of the first and second devices are of a first type, wherein the second communication interfaces of the first and second devices are of a second type.

18. The system as described in claim 17, wherein the first type is based on a wired link and wherein the second type is based on a wireless link.

19. The system as described in claim 17, wherein the second type is a radio frequency (RF) interface.

20. The system as described in claim 17, wherein the second type is a Bluetooth interface.

21. The system as described in claim 15, wherein the respective device data is communicated through an extension of a link layer discovery protocol (LLDP).
