Abstract

A data bridge controls packet transfers between network fabrics forming a closed network, such as a vehicular network and a home network. The data bridge includes two or more sets of modules, each of which communicates with a different network fabric. When a packet is to be delivered between network fabrics, a first set of modules, which is used to communicate with a first network fabric, decides whether to accept the packet or discard it. If the packet is accepted, it is delivered to a second set of modules, which is used for communicating with a second network fabric. The second set of modules makes a second, independent decision about whether the packet will be sent to the second network fabric. Each set of modules can base its decision on packet content type, and may discard any packet not to be delivered to the other network.

First claim

What is claimed is:

1. A vehicle data processing system comprising:
a plurality of processing resources within a first vehicle; and
a wireless communications interface within the first vehicle, wherein the plurality of processing resources and the wireless communications interface are configured to:
determine that processing resource offloading of the first vehicle is desired;
detect a proximately located second vehicle for possible processing resource offloading;
wirelessly transmit a process resource offloading request to the second vehicle;
wirelessly receive a process resource offloading response from the second vehicle; and
wirelessly communicate with the second vehicle to receive process resource offloading services from the second vehicle.

2. The vehicle data processing system of claim 1 , wherein the plurality of processing resources and the wireless communications interface are configured to detect the proximately located second vehicle for possible processing resource offloading via monitoring of wireless communications of the second vehicle.

3. The vehicle data processing system of claim 1 , wherein the plurality of processing resources and the wireless communications interface are configured to monitor a quality of wireless communications with the second vehicle to ensure that process resource offloading is supported.

4. The vehicle data processing system of claim 1 , wherein the plurality of processing resources and the wireless communications interface are configured to detect the proximately located second vehicle for possible processing resource offloading based upon a determination that the second vehicle is traveling in proximity to the first vehicle.

5. The vehicle data processing system of claim 1 , wherein the plurality of processing resources and the wireless communications interface are configured to determine that processing resource offloading of the first vehicle is desired based upon first vehicle sensor data that is collected.

6. The vehicle data processing system of claim 1 , further comprising:
a mission critical network fabric within the first vehicle;
a non-mission critical network fabric within the first vehicle; and
at least one packet interface coupled between the wireless communications interface and at least one of the mission critical network fabric and the non-mission critical network fabric.

7. The vehicle data processing system of claim 6 , wherein the at least one packet interface is configured to route data packets based upon their priorities.

8. The vehicle data processing system of claim 7 , wherein the at least one packet interface:
routes mission critical data packets between the wireless communications interface and the mission critical network fabric; and
routes non-mission critical data packets between the wireless communications interface and the non-mission critical network fabric.

9. The vehicle data processing system of claim 1 , further comprising:
a network fabric within the first vehicle; and
at least one packet interface coupled between the wireless communications interface and the network fabric.

10. The vehicle data processing system of claim 9 , wherein the at least one packet interface is configured to route data packets between the wireless communications interface and the network fabric based upon their priorities.

11. The vehicle data processing system of claim 9 , wherein the at least one packet interface:
routes mission critical data packets between the wireless communications interface and the network fabric with a first priority; and
routes non-mission critical data packets between the wireless communications interface and the network fabric with a second priority that is a lesser priority than the first priority.

12. A method for vehicle data processing comprising:
servicing data processing via a plurality of processing resources within a first vehicle;
wirelessly communicating via a wireless communications interface within the first vehicle;
determining that processing resource offloading of the first vehicle is desired;
detecting a proximately located second vehicle for possible processing resource offloading;
wirelessly transmitting a process resource offloading request to the second vehicle via the wireless communications interface;
wirelessly receiving a process resource offloading response from the second vehicle via the wireless communications interface; and
wirelessly communicating with the second vehicle to receive process resource offloading services from the second vehicle.

13. The method of claim 12 , wherein detecting the proximately located second vehicle for possible processing resource offloading comprises monitoring of wireless communications of the second vehicle.

14. The method of claim 12 , further comprising monitoring a quality of wireless communications with the second vehicle to ensure that process resource offloading is supported.

15. The method of claim 12 , further comprising detecting the proximately located second vehicle for possible processing resource offloading based upon a determination that the second vehicle is traveling in proximity to the first vehicle.

16. The method of claim 12 , further comprising determining that processing resource offloading of the first vehicle is desired based upon first vehicle sensor data that is collected.

17. The method of claim 12 , further comprising routing data packets between a mission critical network fabric within the first vehicle and a non-mission critical network fabric within the first vehicle based upon priorities of the data packets.

18. The method of claim 17 , further comprising:
routing mission critical data packets between the wireless communications interface and the mission critical network fabric; and
routing non-mission critical data packets between the wireless communications interface and the non-mission critical data packets.

19. A vehicle data processing system comprising:
a plurality of processing resources within a vehicle; and
a wireless communications interface within the first vehicle, wherein the plurality of processing resources and the wireless communications interface are configured to:
determine that processing resource offloading of the vehicle is desired;
detect an external wireless network for possible processing resource offloading;
wirelessly transmitting a process resource offloading request via the external wireless network;
wirelessly receiving a process resource offloading response from the external wireless network; and
wirelessly communicating with the external wireless network to receive process resource offloading services from a servicing device via the external wireless network.

20. The vehicle data processing system of claim 19 , further comprising:
a mission critical network fabric within the vehicle;
a non-mission critical network fabric within the vehicle; and
at least one packet interface coupled between the wireless communications interface and at least one of the mission critical network fabric and the non-mission critical network fabric that is configured to:
route mission critical data packets between the wireless communications interface and the mission critical network fabric; and
route non-mission critical data packets between the wireless communications interface and the non-mission critical network fabric.
