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.
