3. Terms
 AUTOSAR: AUTomotive Open System Architecture
 SDU: Service Data Unit
 PCI: Protocol Control Information
 PDU: Protocol Data Unit
 I-PDUs: Interaction Layer Protocol Data Units
 IpduM: I-PDU Multiplexer

4. AUTOSAR Static architecture

5. Communication stack
 BUS: to be replaced by “LIN,
CAN, flex-ray or ethernet”

6. Communication stack
 Sections A, B and C
 “A” for transmission/reception
 “B” for Buses’ status.
 “C” for the NW status.
 The interface layer
 Drivers abstraction layer
 TP: package segmentation
 PDUR: routing on different buses
 COM: signal cyclicity

7. CAN STACK

9. PDUR: PDU ROUTER
PDU Router:
PDU Router is a module responsible for routing the PDU to the respective Bus Specific
Interface modules.Above the PduR module all the PDUs are protocol independent, and
below PduR all the PDUs are routed to the protocol specific modules. PduR is also
responsible for PDU level gatewaying i.e. transmitting the received PDU from one Bus
Specific Interface module to other Bus Specific Interface module.
Gatewaying can also be done when a PDU is to be routed from one controller to another
over the same protocol.
