Multi-level video processing within a vehicular communication network

1. A system for controlling power distribution within a vehicular communication network, comprising:

a power source equipment comprising a first port in communication with a network node module of a device, and a Power over Ethernet (POE) management module;

wherein the POE management module is configured to:

enable POE to the device via the first port,

monitor a current draw of the device,

determine whether the current draw of the device exceeds a threshold,

disable POE to the device, responsive to determining that the current draw exceeds the threshold, and

subsequently re-enable POE to the device in a retry mechanism.

2. The system of claim 1 , wherein the POE management module is further configured to, after re-enabling POE to the device in the retry mechanism:

monitor the current draw of the device,

determine whether the current draw of the device exceeds the threshold, and

re-disable POE to the device, responsive to determining that the current draw exceeds the threshold.

3. The system of claim 2 , wherein the POE management module is further configured to flag the device as damaged, responsive to determining that the current draw exceeds the threshold after repeating the retry mechanism a predetermined number of times.

4. The system of claim 1 , wherein the POE management module is further configured to:

determine that the device should be reset,

transmit a command to reset the device via the first port, responsive to the determination that the device should be reset,

disable POE to the device, and

subsequently re-enable POE to the device after a predetermined time period.

5. The system of claim 1 , wherein the POE management module is further configured to:

determine that a network link to the device should be reset,

transmit a command to reset the network link to the device, responsive to the determination that the network link should be reset,

disable POE to the device, and

subsequently re-enable POE to the device after a predetermined time period.

6. The system of claim 5 , wherein the command to reset the network link comprises a layer 2 control protocol.

7. The system of claim 1 , wherein the device comprises a network node providing communications for a plurality of additional devices.

8. A system for controlling power distribution within a vehicular communication network, comprising:

a power source equipment comprising a first port in communication with a network node module of a device, and a Power over Ethernet (POE) management module;

wherein the POE management module is configured to:

enable POE to the device via the first port,

monitor a current draw of the device,

determine whether the current draw of the device exceeds a threshold, and

transmit a request for information to the device, responsive to determining that the current draw exceeds the threshold.

9. The system of claim 8 , wherein the POE management module is further configured to disable POE to the device, responsive to determining that the current draw exceeds the threshold and that a favorable response to the request for information was not received from the device within a predetermined time period.

10. A method for controlling power distribution within a vehicular communication network, comprising:

enabling, by a Power over Ethernet (POE) management module of power source equipment comprising a first port in communication with a network node module of a device, POE to the device via the first port,

monitoring, by the POE management module, a current draw of the device,

determining, by the POE management module, whether the current draw of the device exceeds a threshold,

disabling, by the POE management module, POE to the device, responsive to determining that the current draw exceeds the threshold, and

subsequently re-enabling POE to the device in a retry mechanism.

11. The method of claim 10 , further comprising, after re-enabling POE to the device in the retry mechanism:

monitoring the current draw of the device,

determining whether the current draw of the device exceeds the threshold, and

re-disabling POE to the device, responsive to determining that the current draw exceeds the threshold.

12. The method of claim 11 , further comprising flagging the device as damaged, responsive to determining that the current draw exceeds the threshold after repeating the retry mechanism a predetermined number of times.

13. The method of claim 10 , further comprising:

determining that the device should be reset,

transmitting a command to reset the device via the first port, responsive to the determination that the device should be reset,

disabling POE to the device, and

subsequently re-enabling POE to the device after a predetermined time period.

14. The method of claim 10 , further comprising:

determining that a network link to the device should be reset,

transmitting a command to reset the network link to the device, responsive to the determination that the network link should be reset,

disabling POE to the device, and

subsequently re-enabling POE to the device after a predetermined time period.

15. The method of claim 14 , wherein the command to reset the network link comprises a layer 2 control protocol.

16. The method of claim 10 , wherein the device comprises a network node providing communications for a plurality of additional devices.

17. The method of claim 16 , further comprising transmitting a request for information to the device, responsive to determining that the current draw exceeds the threshold.

18. The method of claim 17 , further comprising disabling POE to the device, responsive to determining that the current draw exceeds the threshold and that a favorable response to the request for information was not received from the device within a predetermined time period.
