用語(terms)
| Term | Description |
|---|---|
| contained I-PDU | I-PDU being transported inside a Container I-PDU |
| Container I-PDU | I-PDU serving as the Container collecting several I-PDUs to be transported together (e.g. in one frame) |
| dynamic part | According to the value of the selector field some parts of the I-PDU have a different layout. These parts of the I-PDU that can contain different signals are called dynamic part. The dynamic part must not necessarily be contiguous. |
| Multi-PDU-to-Container Mapping | Multi-PDU-to-Container Mapping means using the same Container I-PDU with more than one contained I-PDU. To be able to recognize each I-PDU at reception a header containing an ID and the length is placed in front of each contained I-PDU. |
| multiplexed I-PDU I-PDU | multiplexing means using the same PCI of an I-PDU with more than one unique layout of its SDU. A selector field is a part of the SDU of the multiplexed I-PDU. It is used to distinguish the different layouts of the multiplexed I-PDUs from each other |
| PCI | "Protocol Control Information" A description can be found in AUTOSAR_EXP_LayeredSoftwareArchitecture [3]. |
| PDU | "Protocol Data Unit" A description can be found in AUTOSAR_EXP_LayeredSoftwareArchitecture [3]. |
| PduR | Module that transfers I-PDUs from one module to another module. The I-PDU Router can be utilized for gateway operations and for internal routing purposes. |
| SDU | "Service Data Unit" A description can be found in AUTOSAR_EXP_LayeredSoftwareArchitecture [3]. |
| selector field | The selector field is part of a multiplexed I-PDU. It consists of contiguous bits. The value of the selector field selects the layout of the multiplexed part of the I-PDU. |
| static part | Some parts/signals of the I-PDU may be the same regardless of the selector field. Such a part is called static part. The static part must not necessarily be contiguous. |
