Claim 18:
19. An apparatus comprising:
a processor;
memory in electronic communication with the processor; and
instructions stored in the memory, the instructions being executable by the processor to:
receive a message over a communication busy using a device driver associated with the communication bus, wherein the message comprises a protocol data unit (PDU);
detect, using a controller module associated with the communication bus, a message identifier included in the message;
determine, at an interface module of a same type as the communication bus, based at least in part on receiving the message identifier from the controller module and using a lookup table (LUT) of a same type as the controller module, a first PDU identifier for the PDU that is unique to the interface module; and
transmit, by the interface module, the PDU and the first PDU identifier to a router module included in a first layer of a layered communication architecture.
