Claims

1. A vehicle communication network comprising:

a plurality of network elements;

a plurality of communication links joining the network elements in a point-to-point configuration, at least a portion of the plurality of communication links being specified in accordance with a shared-access bus protocol; and

the plurality of communication links being arranged to communicate data packets between the network elements, wherein the shared-access bus protocol comprises of one of CAN, LIN, J1850, TTP, Flexray and MOST bus protocols.

2. The vehicle communication network of claim 1, wherein the network elements are operative to control communication of the data packets on the communication links.

3. The vehicle communication network of claim 1, wherein the shared-access bus protocol comprises at least two different shared-access bus protocols and wherein the communication links are specified in accordance with at least one of the two different shared-access bus protocols.

4. The vehicle communication network of claim 1 further comprising a system manager.

5. The vehicle communication network of claim 1, wherein each of the plurality of communication links is one of a bi-directional and a uni-directional link.

6. The vehicle communication network of claim 1, wherein the communication links and network elements are configured as a switch fabric.

7. The vehicle communication network of claim 1, wherein the communication links and network elements are configurable to provide a plurality of communication paths between a first network element and a second network element via one or more communication links and one or more intermediary network elements.

8. A communication system comprising:

a vehicle having disposed therein a plurality of network elements;

a plurality of communication links joining the network elements in a point-to-point configuration, at least a portion of the plurality of communication links being specified in accordance with a shared-access bus protocol;

at least one of the network elements being coupled to a device, system, sub-system, sensor or actuator of the vehicle; and

the plurality of communication links being arranged to communicate data packets between the network elements, wherein the shared-access bus protocol comprises one of TTP, CAN, LIN, Flexray, J1850 and MOST bus protocols.

9. The communication system of claim 8, wherein the network elements are operative to control communication of the data packets on the communication links.

10. The communication system of claim 8, wherein the shared-access bus protocol comprises at least two different shared-access bus protocols and wherein the communication links are specified in accordance with at least one of the two different shared-access bus protocols.

11. The communication system of claim 8, further comprising a system manager.

12. The communication system of claim 8, wherein the communication links and network elements are configured as a switch fabric.

13. The communication system of claim 8, wherein the communication links and network element are configurable to provide a plurality of communication paths between a first network element and a second network element via one or more communication links and one or more intermediary network elements.

14. A method of providing communications within a vehicle comprising:

providing within the vehicle a plurality of network elements;

communicatively coupling the plurality of network elements using a plurality of communication links, at least a portion of which are shared access communication links comprising one of TTP, CAN, LIN, Flexray, J1850 and MOST bus protocols;

configuring a data packet for communication between the network elements, and

communicating the data packet between the network elements using the communication links.

15. The method of claim 14, further comprising coupling at least one of the network elements to one of a device, system, sub-system, sensor or actuator of the vehicle.

16. The method of claim 14, wherein the step of communicating the data packet between the network elements comprising communicating the data packet on one of a plurality of communication paths comprising communication links and network elements between a first network element and a second network element.

17. A vehicle communication network comprising:

a plurality of network elements;

a plurality of communication links joining the network elements in a point-to-point configuration, the plurality of communication links being arranged to communicate data packets between the network elements;

wherein a first network element and a second network element are coupled with a communication link using a first network protocol, the second network element coupled to another network element different from the first network element with a communication link using a second network protocol, and the first network element coupled to another network element different from the second network element with a communication link using a third network protocol.

18. The vehicle communication network of claim 17, wherein the second and third network protocol is selected from the set of protocols consisting of CAN, LIN, J1850, TTP, Flexray and MOST bus protocols.

19. The vehicle communication network of claim 17, wherein the another network element coupled to the first element and the another network element coupled to the second network element are the same network element.

20. The vehicle communication network of claim 19, wherein at least one of the first, second, and third network protocols are specified in accordance with a shared-access bus protocol.

21. The vehicle communication network of claim 19, wherein at least one of the first, second, and third network protocols is not a shared-access bus protocol.

22. The vehicle communication network of claim 19, wherein at least one of the protocols comprises one of CAN, LIN, J1850, TTP, Flexray and MOST bus protocols.

23. The vehicle communication network of claim 17, wherein at least a portion of the network is an asynchronous network.

24. The vehicle communication network of claim 17, wherein the data packets are communicated discretely while in transit.

25. The method of claim 14, wherein communicating the data packet comprises communicating the packet between the network elements asynchronously.

26. The method of claim 14, wherein communicating the data packet comprises communicating the data packet discretely while in transit.
