Claim 15:
16. A method comprising:
receiving, from a source module in a layered communication architecture, a protocol data unit (PDU) and a first PDU identifier assigned to the PDU;
determining, based at least in part on the first PDU identifier and using a first lookup table (LUT) associated with routing the PDU, a destination module for the PDU and a communication bus over which the PDU is transmitted to the destination module;
determining, based at least in part on the first PDU identifier and using a second LUT associated with the destination module, a second PDU identifier for the PDU that is recognizable by the destination module, wherein the first PDU identifier is unique to the source module, and wherein the second PDU identifier is unique to the destination module; and
transmitting the PDU and the second PDU identifier to the destination module.
