8.2 IPdu Mapping [TPS_SYST_01117] Pdu Gateway support ⌈The IPduMapping arranges those IPdus that are transferred by the Gateway from one PhysicalChannel to the other (or the same) PhysicalChannel in pairs and defines the mapping between them. Each pair consist of a sourceIPdu and a targetIPdu referencing to a PduTriggering.⌋() For FlexRay: If a Pdu is gatewayed to more than one PhysicalChannel of the same CommunicationCluster, all of this gateway relationships shall be specified. Therefore, all affected PduTriggerings shall be referenced in the gateway mappings. [TPS_SYST_01118] Support of Multicast Pdu routing ⌈The 1:n multicast routing is supported with the definition of several IPduMappings where the sourceIPdu refers to the same PduTriggering.⌋() [TPS_SYST_02143] Support of Multisource Pdu routing ⌈The n:1 routing is supported with the definition of several IPduMappings where the targetIPdu refers to the same PduTriggering.⌋() Please note that in case of n:1 routing by a local module (e.g. COM, Dcm) it shall be enforced at run-time that at most one routing path is active (i.e., enabled via PduR_EnableRouting()). In case of n:1 routing by a pure gateway routing (either TP or IF) all routing paths can be active at run time. [TPS_SYST_02207] Routing on the fly ⌈If routing on the fly is not possible in case: • there is more than one destination routing path or • the routing path uses the Interface (IF) API instead of Transport Protocol (TP) API then IPduMapping.pdurTpChunkSize will be ignored in the Ecu configuration.⌋() System Template IPduMapping + pduMaxLength: PositiveInteger [0..1] + pdurTpChunkSize: PositiveInteger [0..1] PduMappingDefaultValue TargetIPduRef DefaultValueElement + elementByteValue: Integer + elementPosition: Integer Identifiable PduTriggering «atpMixed» DocumentationBlock +defaultValue 0..1 +sourceIPdu 1 +introduction 0..1 +defaultValueElement 1..* +targetIPdu 1 +targetIPdu 1 Figure 8.3: I-Pdu Mapping (Fibex4Multiplatform: IPduMapping) Class IPduMapping Package M2::AUTOSARTemplates::SystemTemplate::Fibex::Fibex4Multiplatform Note Arranges those IPdus that are transferred by the gateway from one channel to the other in pairs and defines the mapping between them.
