Patent ID: 8750319

Claim:
A data bridge to control packet transfers between network fabrics of a closed vehicular network carrying data having different priorities, the data bridge comprising: packet ingress circuitry coupled to a first network fabric and a second network fabric, a majority of data carried by the first network having a first priority and a majority of data carried by the second network having a second priority that differs from the first priority; packet egress circuitry coupled to the first network fabric and the second network fabric; processing circuitry coupled to the packet ingress circuitry and the packet egress circuitry; the processing circuitry operable to: determine a status of a vehicle associated with the vehicular network; determine, based on the status of the vehicle, that resource sharing between the first network fabric and the second network fabric is allowed; determine first priority routing of a first packet from the first network fabric to the second network fabric based on packet content type of the first packet and priority conditions of the second network fabric; receive a second packet from the second network fabric that includes a request for a resource of the first network fabric and that is to be delivered from the second network fabric to the first network fabric; determine that the requested resource is available; determine second priority routing of the second packet, based on packet content type of the second packet and priority conditions of the first network fabric; and forward the second packet to the first network fabric.
