# 用語(terms)
|Term| Description¥
|:--|:--|
|I- |Relative to upper AUTOSAR Layer (e.g. COM, DCM etc.)
|L-| Relative to the FlexRay Interface module.
|N-| Relative to the FlexRay Transport Protocol Layer. 
|Fr L-SDU |This is the SDU of the FlexRay Interface module. It is similar to Fr N-PDU but from the FlexRay Interface module point of view.
|Fr L-SduId |This is the unique identifier of a Fr-L-SDU within the FlexRay Interface. It is used for referencing L-SDU’s routing properties.
|Fr N-PDU |This is the PDU of the FlexRay Transport Layer. It contains address information, protocol control information and data (the whole Fr N-SDU or a part of it).
|Fr N-SDU |This is the SDU of the FlexRay Transport Layer. In the AUTOSAR architecture, it is a set of data coming from the PDU Router.
|Fr N-SduId |Unique N-SDU identifier within the FlexRay Transport Layer. It is used to reference NSDU’s routing properties.
|I-PDU| This is the PDU of the upper AUTOSAR Layers modules (e.g. COM, DCM etc.). If data transfer via FlexRay Transport Protocol is configured, I-PDU is similar to an FrTp N-SDU.
|PDU |In layered systems, it refers to a data unit that is specified in the protocol of a given layer. This contains user data of that layer (SDU) plus possible protocol control information. Furthermore, the PDU of layer X is the SDU of its lower layer X-1 (i.e. (X)-PDU = (X1)-SDU).
|PduInfoType| This type refers to a structure used to store basic information to process the transmission\reception of a PDU (or a SDU), namely a pointer to its payload in RAM and the corresponding length (in bytes).
|Channel| A channel is a resource of the FrTp module to handle communication links to other communication nodes from FrTp’s point of view (transferring Fr N-PDUs).
|Connection |A connection specifies a communication link between different communication nodes from FrTp’s point of view. A connection defines the sender / receiver relation of communication nodes
|PCI |Protocol Control Information
|e.g. |lat. ‘exempli gratia’ – engl. for example
|i.e.| lat. 'id est' – engl. that is
|CanTp |CAN Transport Protocol
|LinTp |LIN Transport Protocol
|CF |Consecutive Frame Fr N-PDU
|COM |AUTOSAR Communications module
|DCM| Diagnostic Communication Manager module
|DET| Default Error Tracer
|FC |Flow Control Fr N-PDU
|Fr| FlexRay Driver module
|FrIf |FlexRay Interface module
|FrTp| FlexRay Transport Protocol Layer
|PduR| PDU Router
|SF |Start Frame Fr N-PDU
|LF| Last Frame Fr N-PDU
|TP |Transport Protocol Layer
|SDU |In layered systems, this refers to a set of data that is sent by a user of the services of a given layer, and is transmitted to a peer service user, whilst remaining semantically unchanged.
|AUTOSAR |Automotive Open System Architecture
|SWS| Software Specification
|MISRA |Motor Industry Software Reliability Association
|ISO|International Standard Organisation
|ID| Identifier
|OS |Operating System
|MCAL| Microcontroller Abstraction Layer
|CPU |Central Processing Unit
|ROM |Read Only Memory
|RAM |Random Access Memory
|STF |Start Frame (please refer to ISO 10681-2)
|AF |Acknowledge Frame (please refer to ISO 10681-2)
|SN |Sequence Number (please refer to ISO 10681-2)
|FrTp_As |Timer Parameter for a sender. Time for transmission of the FlexRay frame (any N_PDU) on the sender side. (please refer to ISO 10681-2)
|FrTp_Ar |Timer Parameter for a receiver. Time for transmission of the FlexRay frame (any N_PDU) on the receiver side (please refer to ISO 10681-2)
|FrTp_BS |Timer Parameter for a sender. Time until reception of the next FlowControl N_PDU. (please refer to ISO 10681-2)
|FrTp_Br| Timer Parameter for a receiver. Time until transmission of the next FlowControl N_PDU. (please refer to ISO 10681-2)
|FrTp_Cs |Timer Parameter for a sender. Time until transmission of the next ConsecutiveFrame N_PDU/LastFrame N_PDU. (please refer to ISO 10681-2)
|FrTp_Cr |Timer Parameter for a receiver. Time until reception of the next ConsecutiveFrame N_PDU (please refer to ISO 10681-2)
