Bridge routing module
First Claim
1. A bridge-routing module to be incorporated into a closed network fabric, the bridge-routing module comprising:
- a plurality of interface circuits configured to be coupled to at least one of a switch module and another bridge-routing module via the closed network fabric;
an ingress circuit coupled to receive packets from the closed network fabric via at least one of the plurality of interface circuits;
an egress circuit coupled to transmit packets to the closed network fabric via at least one of the plurality of interface circuits; and
memory configured to store information associating packet content types with packet routing parameters; and
processing circuitry configured to;
analyze a packet to identify a packet content type and to determine if the packet is a mission critical packet;
when the packet is a mission critical packet and the packet is received from a packet source, add an indication to a header of the packet to identify the packet as a mission critical packet;
determine a packet routing parameter of the packet routing parameters based, at least in part, on the packet content type; and
control ingress or egress of the packet in accordance with the packet routing parameter.

Abstract
A bridge routing module can be incorporated into a closed network fabric, such as a vehicular network. The bridge routing module includes an interface circuit to be coupled to other elements of the closed network fabric, for example other bridge routing modules or switch modules. The bridge routing module includes memory to store information associating packet content types with packet routing parameters, among other things. A processing module included in the bridge routing module analyzes packets to identify the type of content carried by the packets, and determines packet routing parameters based on the packet'"'"'s content type. Ingress and egress of the packet are controlled in accordance with the packet routing parameters determined by the processing module.
