autosar - 是否需要将 ContainerIPDU 映射到 arxml 中的框架

Question

是否需要将 Container I PDU 映射到框架？

还需要在任何物理通道上为 ContainerIPDU 创建 IPDUTriggering。

ContainerIPDU中的所有引用PDUTriggerings是否必须来自同一个物理通道？

谢谢。

Depends, yes, no :)

As ContainerIPdu is just a specific kind of IPdu, it needs to be mapped to a Frame if the underlying CommunicationCluster requires a mapping to Frames (which is not the case for Ethernet).

For the same reason, a PduTriggering that refers to the ContainerIPdu needs to be aggregated by all PhysicalChannels on which the ContainerIPdu is supposed to be transmitted.

It is not required that the PduTriggerings that refer to the contained IPdus of a ContainerIPdu belong to the same PhysicalChannel that owns the PduTriggering that refers to the ContainerIPdu itself. But for the actual transport of a contained IPdu on a given PhysicalChannel the latter needs to own PduTriggerings that refer to the respective contained IPdus.
