简介(Introduction)

PduR模块主要为通信接口模块(如CanIf)，传输协议模块(如CanTp)，诊断服务模块(如Dcm)，通信服务模块(如Com, LdCom)，以及IpduM，SecOc等模块提供基于PDU的路由服务。PduR模块主要实现基于PDU的接收路由(PDU从CanIf→PduR→Com)，发送路由(Com→PduR→CanIf)，网关路由功能(CanIf→PduR→CanIf)。

The PduR module provides PDU-based routing services for communication interface modules (e.g., CanIf), transport protocol modules (e.g., CanTp), diagnostic service modules (e.g., Dcm), communication service modules (e.g., Com, LdCom), as well as modules such as IpduM and SecOc. The PduR module implements PDU-based reception routing (PDU from CanIf→PduR→Com), transmission routing (Com→PduR→CanIf), and gateway routing (CanIf→PduR→CanIf).

PduR模块层次图(PduR Module Hierarchy Diagram)

与PduR模块存在交互的模块可分为三类：1.下层模块(如CanIf, CanTp)；2.上层模块(如Com, Dcm)；3.既是上层又是下层模块(IpduM, SecOC)。 PduR与所有交互模块间实现IF PDU和TP PDU的接收与发送功能。

Modules interacting with the PduR module fall into three categories: 1. Lower-layer modules (e.g., CanIf, CanTp); 2. Upper-layer modules (e.g., Com, Dcm); 3. Modules serving as both upper and lower layers (IpduM, SecOC). The PduR module handles reception and transmission of IF PDUs and TP PDUs with all interacting modules.

功能描述(Functional Description)

特性(Features)

发送路由功能(Transmit Routing Function)

Tx PDU的发送分为两种方式(IF和TP)，在PduR模块实现TP PDU的1:1发送路由，IF PDU的1:N发送路由。通过PduR模块的路由配置可以为上层屏蔽网络细节，上层模块专注于Tx PDU报文数据的封装。

Tx PDU transmission operates in two modes (IF and TP). The PduR module implements 1:1 transmit routing for TP PDUs and 1:N transmit routing for IF PDUs. The PduR routing configuration shields upper layers from network details, allowing upper-layer modules to focus on Tx PDU message data encapsulation.

接收路由功能(Receive Routing Function)

Rx PDU的接收分为两种方式(IF和TP)，在PduR模块实现TP PDU的1:N接收路由，IF PDU的1:N接收路由。当PDU从下层模块接收到，根据PduR配置的路由路径传递到上层模块。上层模块不必关注网络细节，专注于接收PDU的解析。

Rx PDU reception operates in two modes (IF and TP). The PduR module implements 1:N receive routing for TP PDUs and 1:N receive routing for IF PDUs. When a PDU is received from a lower-layer module, it is delivered to upper-layer modules according to the PduR-configured routing path. Upper-layer modules do not need to focus on network details and can concentrate on received PDU parsing.

网关路由功能(Gateway Routing Function)

PDU的网关同样分为IF/TP两种方式，IF网关支持1:N，TP网关也支持1:N，不涉及任何报文数据的变化，收发报文速率保持一致(如果目的端报文长度小于源端报文长度，会进行截断以确保网关功能正常)。 需注意PDU的网关不能IF、TP混用，即接收的IF PDU只能通过发送IF PDU进行转发，接收的TP PDU只能通过发送TP PDU进行转发。

PDU gateway operation is also divided into IF/TP modes. The IF gateway supports 1:N routing, and the TP gateway also supports 1:N routing. This process does not modify message data, and transmission/reception rates remain consistent (if the destination message length is shorter than the source message length, truncation occurs to ensure successful gateway operation). Note that PDU gateways cannot mix IF and TP modes: received IF PDUs can only be forwarded via transmitted IF PDUs, and received TP PDUs can only be forwarded via transmitted TP PDUs.

路由控制功能(Routing Control Function)

PduR的路由控制以RoutingPathGroup为单位进行启用/禁用控制，而PduRRoutingPath通过PduRRoutingPathGroupRef可以关联N个RoutingPathGroup，只要关联的至少一个RoutingPathGroup启用，则对应的PduRDestPdu使能。

PduR routing control enables/disables RoutingPathGroups as units. PduRRoutingPath can associate with N RoutingPathGroups via PduRRoutingPathGroupRef. The corresponding PduRDestPdu is enabled when at least one associated RoutingPathGroup is enabled.

Reentrancy

Reentrant

Parameters

Dir	Name	Description
[in]	id	Identification of the transmitted I-PDU.
[in]	info	Provides the destination buffer (SduDataPtr) and the number of bytes to be copied (SduLength). If not enough transmit data is available, no data is copied by the upper layer module and BUFREQ_E_BUSY is returned. The lower layer module may retry the call. An SduLength of 0 can be used to indicate state changes in the retry parameter or to query the current amount of available data in the upper layer module. In this case, the Sdu DataPtr may be a NULL_PTR.
[in]	retry	This parameter is used to acknowledge transmitted data or to retransmit data after transmission problems. If the retry parameter is a NULL_PTR, it indicates that the transmit data can be removed from the buffer immediately after it has been copied. Otherwise, the retry parameter must point to a valid RetryInfoType element. If TpDataState indicates TP_CONFPENDING, the previously copied data must remain in the TP buffer to be available for error recovery. TP_DATACONF indicates that all data that has been copied before this call is confirmed and can be removed from the TP buffer. Data copied by this API call is excluded and will be confirmed later. TP_DATARETRY indicates that this API call shall copy previously copied data in order to recover from an error. In this case TxTpDataCnt specifies the offset in bytes from the current data copy position.
[out]	availableDataPtr	Indicates the remaining number of bytes that are available in the upper layer module’s Tx buffer. availableDataPtr can be used by TP modules that support dynamic payload lengths (e.g. FrIsoTp) to determine the size of the following CFs.

Return type

配置(Configuration)

发送路由配置(Transmit Routing Configuration)

IF PDU的发送：

IF PDU Transmission:

在PduR添加配置路由PduRRoutingPath，为每一个PduRDestPdu配置一个PduRRoutingPath(IF PDU 1:N路由场景就存在N个PduRRoutingPath，这N个PduRRoutingPath的PduRSrcPduRef相同)。 其中PduRRouteType配置为IF，配置项PduRSrcPduRef关联一个PduRSrcPdu，该PduRSrcPdu通过PduRSrcPduRef关联的PDU(EcuC)与上层模块发送Tx PDU关联， 配置项PduRDestPduRef关联一个PduRDestPdu，该PduRDestPdu通过PduRDestPduRef关联的PDU与下层IF模块关联。 上层模块通过调用PduR_<Up>Transmit或者下层模块通过调用PduR_<Lo>TriggerTransmit(传递到上层)请求PDU的发送， 发送成功后调用上层PduR_<LoTxConfirmation进行发送成功确认。

Configure PduRRoutingPath in PduR, assigning one PduRRoutingPath per PduRDestPdu (IF PDU 1:N routing requires N PduRRoutingPaths sharing the same PduRSrcPduRef). Set PduRRouteType to IF, where PduRSrcPduRef associates with a PduRSrcPdu linked to the upper module’s Tx PDU via PduRSrcPduRef-associated PDU (EcuC). PduRDestPduRef associates with a PduRDestPdu linked to the lower IF module via PduRDestPduRef-associated PDU. Upper modules call PduR_<Up>Transmit or lower modules call PduR_<Lo>TriggerTransmit (forwarded to upper layer) to request PDU transmission. Upon successful transmission, upper layer PduR_<LoTxConfirmation is called for transmission confirmation.

TP PDU的发送：

TP PDU Transmission:

在PduR添加配置路由PduRRoutingPath，为每一个PduRDestPdu配置一个PduRRoutingPath。其中PduRRouteType配置为TP，配置项PduRSrcPduRef关联一个PduRSrcPdu， 该PduRSrcPdu通过PduRSrcPduRef关联的PDU(EcuC)与上层模块发送Tx PDU关联，配置项PduRDestPduRef关联一个PduRDestPdu，该PduRDestPdu通过PduRDestPduRef关联的PDU与下层TP模块关联。 上层模块通过调用PduR_<Up>Transmit请求PDU的发送，下层模块通过调用PduR_<LoTp>CopyTxData(传递到上层)来获取PDU发送数据段， 下层模块通过调用PduR_<LoTp>TxConfirmation(传递到上层)通知上层发送结束(成功/失败)。

Configure PduRRoutingPath in PduR, assigning one PduRRoutingPath per PduRDestPdu. Set PduRRouteType to TP, where PduRSrcPduRef associates with a PduRSrcPdu linked to the upper module’s Tx PDU via PduRSrcPduRef-associated PDU (EcuC). PduRDestPduRef associates with a PduRDestPdu linked to the lower TP module via PduRDestPduRef-associated PDU. Upper modules call PduR_<Up>Transmit to request PDU transmission. Lower modules call PduR_<LoTp>CopyTxData (forwarded to upper layer) to obtain PDU transmission data segments, and call PduR_<LoTp>TxConfirmation (forwarded to upper layer) to notify the upper layer of transmission completion (success/failure).

接收路由配置(Receive Routing Configuration)

IF PDU的接收：

IF PDU Reception:

在PduR添加配置路由PduRRoutingPath，为每一个PduRDestPdu配置一个PduRRoutingPath(1:N路由场景就存在N个PduRRoutingPath，这N个PduRRoutingPath的PduRSrcPduRef相同)。 其中PduRRouteType配置为IF，配置项PduRSrcPduRef关联一个PduRSrcPdu，该PduRSrcPdu通过PduRSrcPduRef关联的PDU(EcuC)与下层IF模块接收Rx PDU关联， 配置项PduRDestPduRef关联一个PduRDestPdu，该PduRDestPdu通过PduRDestPduRef关联的PDU与上层模块关联。下层模块通过调用PduR_<Lo>RxIndication将接收报文传递给上层。

Configure PduRRoutingPath in PduR, assigning one PduRRoutingPath per PduRDestPdu (1:N routing requires N PduRRoutingPaths sharing the same PduRSrcPduRef). Set PduRRouteType to IF, where PduRSrcPduRef associates with a PduRSrcPdu linked to the lower IF module’s Rx PDU via PduRSrcPduRef-associated PDU (EcuC). PduRDestPduRef associates with a PduRDestPdu linked to the upper module via PduRDestPduRef-associated PDU. Lower modules call PduR_<Lo>RxIndication to forward received messages to the upper layer.

TP PDU的接收：

TP PDU Reception:

在PduR添加配置路由PduRRoutingPath，为每一个PduRDestPdu配置一个PduRRoutingPath(1:N路由场景就存在N个PduRRoutingPath，这N个PduRRoutingPath的PduRSrcPduRef相同)。 其中PduRRouteType配置为TP，配置项PduRSrcPduRef关联一个PduRSrcPdu，该PduRSrcPdu通过PduRSrcPduRef关联的PDU(EcuC)与下层TP模块接收Rx PDU关联， 配置项PduRDestPduRef关联一个PduRDestPdu，该PduRDestPdu通过PduRDestPduRef关联的PDU与上层模块关联。调用PduR_<LoTp>StartOfReception， PduR_<LoTp>CopyRxData，PduR_<LoTp>RxIndication完成TP PDU接收流程。

Configure PduRRoutingPath in PduR, assigning one PduRRoutingPath per PduRDestPdu (1:N routing requires N PduRRoutingPaths sharing the same PduRSrcPduRef). Set PduRRouteType to TP, where PduRSrcPduRef associates with a PduRSrcPdu linked to the lower TP module’s Rx PDU via PduRSrcPduRef-associated PDU (EcuC). PduRDestPduRef associates with a PduRDestPdu linked to the upper module via PduRDestPduRef-associated PDU. Call PduR_<LoTp>StartOfReception, PduR_<LoTp>CopyRxData, and PduR_<LoTp>RxIndication to complete the TP PDU reception process.

网关路由配置(Gateway Routing Configuration)

IF PDU的网关：

IF PDU Gateway:

在PduR添加配置路由PduRRoutingPath，为每一个PduRDestPdu配置一个PduRRoutingPath(1:N路由场景就存在N个PduRRoutingPath，这N个PduRRoutingPath的PduRSrcPduRef相同)。其中PduRRouteType配置为IF，配置项PduRSrcPduRef关联一个PduRSrcPdu，该PduRSrcPdu通过PduRSrcPduRef关联的PDU(EcuC)与下层IF模块接收Rx PDU关联，配置项PduRDestPduRef关联一个PduRDestPdu，该PduRDestPdu通过PduRDestPduRef关联的PDU与下层IF模块发送Tx PDU关联，若PduRDestPduRef通过PduRDestPduRef关联的Tx PDU发送方式为TriggerTransmit, 则相应PduRDestPdu的PduRDestPduDataProvision需配置为PDUR_TRIGGERTRANSMIT，反之配置为PDUR_DIRECT。若配置为PDUR_TRIGGERTRANSMIT则必须为该PduRRoutingPath配置queue，以及配置PduRDefaultValueElement来设置PDU初始默认值。配置为PDUR_DIRECT时也可以选择配置queue，以降低丢帧概率。

Configure PduRRoutingPath in PduR, assigning one PduRRoutingPath per PduRDestPdu (1:N routing requires N PduRRoutingPaths sharing the same PduRSrcPduRef). Set PduRRouteType to IF, where PduRSrcPduRef associates with a PduRSrcPdu linked to the lower IF module’s Rx PDU via PduRSrcPduRef-associated PDU (EcuC). PduRDestPduRef associates with a PduRDestPdu linked to the lower IF module’s Tx PDU via PduRDestPduRef-associated PDU. If the Tx PDU transmission mode is TriggerTransmit, configure PduRDestPduDataProvision as PDUR_TRIGGERTRANSMIT; otherwise, configure as PDUR_DIRECT. PDUR_TRIGGERTRANSMIT requires queue configuration for this PduRRoutingPath and PduRDefaultValueElement to set initial PDU default values. PDUR_DIRECT optionally supports queue configuration to reduce frame loss probability.

注意：queue的配置，①需要在相应的PduRRoutingPath中配置非0的PduRQueueDepth值；②添加PduRTxBuffer配置，没有被任何PduRRoutingPath关联的PduRTxBuffer属于Global buffer，存在资源抢占。仅被某一个PduRRoutingPath关联的PduRTxBuffer属于该PduRRoutingPath的Dedicated buffer，该PduRTxBuffer仅可以被该PduRRoutingPath申请；③PduRDestTxBufferRef可以关联最多PduRQueueDepth个PduRTxBuffer，也可以不关联任何PduRTxBuffer。

Note for queue configuration: ① Configure non-zero PduRQueueDepth in the corresponding PduRRoutingPath; ② Add PduRTxBuffer configuration. Unassociated PduRTxBuffers are Global buffers subject to resource contention. PduRTxBuffers associated with only one PduRRoutingPath are Dedicated buffers exclusively available to that path; ③ PduRDestTxBufferRef can associate with up to PduRQueueDepth PduRTxBuffers, or remain unassociated.

TP PDU的网关：

TP PDU Gateway:

在PduR添加配置路由PduRRoutingPath，为每一个PduRDestPdu配置一个PduRRoutingPath(1:N路由场景就存在N个PduRRoutingPath，这N个PduRRoutingPath的PduRSrcPduRef相同)。其中PduRRouteType配置为TP，配置项PduRSrcPduRef关联一个PduRSrcPdu，该PduRSrcPdu通过PduRSrcPduRef关联的PDU(EcuC)与下层TP模块接收Rx PDU关联，配置项PduRDestPduRef关联一个PduRDestPdu，该PduRDestPdu通过PduRDestPduRef关联的PDU与下层TP模块发送Tx PDU关联。若不希望等到全部Rx PDU数据接收完成才开始执行转发，即希望通过”on-the-fly gatewaying”方式进行转发，可通过配置PduRTpThreshold(1:N时只允许最多一个相同PduRSrcPduRef的PduRRoutingPath配置阈值)来实现，当接收数据长度超过该阈值或者接收完成，则触发Tx PDU进行转发。

Configure PduRRoutingPath in PduR, assigning one PduRRoutingPath per PduRDestPdu (1:N routing requires N PduRRoutingPaths sharing the same PduRSrcPduRef). Set PduRRouteType to TP, where PduRSrcPduRef associates with a PduRSrcPdu linked to the lower TP module’s Rx PDU via PduRSrcPduRef-associated PDU (EcuC). PduRDestPduRef associates with a PduRDestPdu linked to the lower TP module’s Tx PDU via PduRDestPduRef-associated PDU. For on-the-fly gatewaying (forwarding before complete reception), configure PduRTpThreshold (only one PduRRoutingPath per PduRSrcPduRef in 1:N routing). Tx PDU forwarding triggers when received data length exceeds this threshold or reception completes.

注意：TP PDU的网关必须配置queue；IF PDU的网关(PduRDestPduDataProvision为PDUR_TRIGGERTRANSMIT的路由必须配置queue；PDUR_DIRECT的路由不需要配queue，如果配置的话可以在一定程度上减少丢帧)

Note: TP PDU gateways require queue configuration; IF PDU gateways with PDUR_TRIGGERTRANSMIT require queues; PDUR_DIRECT routes don’t require queues but can benefit from reduced frame loss if configured.

路由控制配置(Routing Control Configuration)

基于下面原则：(Based on the following principles:)

1. RoutingPathGroup通过配置项PduRIsEnabledAtInit决定初始化之后，该RoutingPathGroup的使能状态

   RoutingPathGroup determines its enable state after initialization through PduRIsEnabledAtInit configuration

2. 所有PduRRoutingPath通过PduRRoutingPathGroupRef会关联0..N个RoutingPathGroup

   All PduRRoutingPaths associate with 0..N RoutingPathGroups via PduRRoutingPathGroupRef

3. 如果该PduRRoutingPath未关联任何RoutingPathGroup 或者 关联的至少一个RoutingPathGroup处于使能状态，则该PduRRoutingPath对应的PduRDestPdu(唯一)为Enable，否则为Disable状态

   PduRDestPdu (unique) is enabled if its PduRRoutingPath is unassociated or associated with at least one enabled RoutingPathGroup; otherwise disabled

4. 运行时，通过调用PduR_EnableRouting/ PduR_DisableRouting来控制RoutingPathGroup的使能状态，从而间接控制PduRDestPdu使能状态

   During runtime, call PduR_EnableRouting/PduR_DisableRouting to control RoutingPathGroup enable states, indirectly controlling PduRDestPdu enable states

5. 未通过PduRRoutingPathGroupRef关联任何RoutingPathGroup的PduRDestPdu初始化之后其状态一直为Enable，不可改变

   PduRDestPdu unassociated with any RoutingPathGroup via PduRRoutingPathGroupRef remains permanently enabled after initialization

多分区控制配置 Multi-Partition(Control Configuration)

如果在工程中EcucPartition存在大于1个的配置，则认为该工程支持多分区/多核。 PduR共有三个独占区保护类型：

Projects with more than one EcucPartition configuration support multi-partition/multi-core. PduR provides three exclusive area protection types:

1. SchM_Enter_PduR_ExclusiveArea_Group是对于Group使能或者禁用的保护，因为一个group下的destpdu均属于一个分区，推荐使用禁中断方式ALL_INTERRUPT_BLOCKING

   SchM_Enter_PduR_ExclusiveArea_Group protects group enable/disable operations. Since destpdus within a group belong to one partition, use ALL_INTERRUPT_BLOCKING

2. SchM_Enter_PduR_ExclusiveArea_Route是对于PduRBuffer申请的保护，

   SchM_Enter_PduR_ExclusiveArea_Route protects PduRBuffer allocation:

   • (推荐)如果所有需要配置PduRBuffer的PduRRoutingPath，均配置了私有buffer，且不存在共用私有buffer，则推荐使用禁中断方式ALL_INTERRUPT_BLOCKING；

     (Recommended) Use ALL_INTERRUPT_BLOCKING if all PduRRoutingPaths requiring PduRBuffer have private buffers without sharing

   • 如果存在共用buffer且会同时申请buffer，则需要配置为OS_SPINLOCK；

     Use OS_SPINLOCK if shared buffers may be allocated concurrently

3. SchM_Enter_PduR_ExclusiveArea_Init是对于初始化时逻辑的保护，推荐使用禁中断方式ALL_INTERRUPT_BLOCKING

   SchM_Enter_PduR_ExclusiveArea_Init protects initialization logic; use ALL_INTERRUPT_BLOCKING
