# 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.
