Figure 7.1: I-PDU ID Example [SWS_PduR_00161] Upstream requirements: SRS_GTW_06003 ⌈The PDU Router module shall identify a routing path uniquely by the combination of source module I-PDU ID (located in the PDU Router configuration) and destination I-PDU IDs (located in the called destination module configurations). ⌋ [SWS_PduR_00766] Upstream requirements: SRS_GTW_06003 ⌈The PDU Router module shall convert the I-PDU ID to the destination module(s) for both Transmit path and TxConfirmation/RxIndication path.⌋ Example: The Com module transmits an I-PDU to CanIf and LinIf. The PduR_Com Transmit is called. The PDU Router module will convert the source I-PDU ID (PDU Router module configuration) to one I-PDU ID for LinIf (LinIf module configuration) and one I-PDU ID for CanIf (CanIf module configuration). The PduInfoType value received from the Com module is copied to the CanIf and LinIf modules without change. Example: The LinIf will call PduR_LinIfTxConfirmation with an I-PDU ID and, dependent on the success of the transmission, with a result E_OK (successful transmission) or E_NOT_OK (not successful transmission). Then the PDU Router module will convert this I-PDU ID and forward the call to Com using Com_TxConfirmation with the converted I-PDU ID and the received result.
