Functions of VIU, ECU, VCU, TSN endpoint, and TSN bridge.

Unit	Function
Vehicle interface unit (VIU)	VIU as a zone gateway to provide a translation from the specific network interfaces of the nodes to the core network
ECU	ECU is highly specialized for controlling its specific device
Vehicle computation unit (VCU)	The VCU coordinates fundamental capabilities to provide vehicle-level behavior
TSN endpoint	The TSN endpoint usually as ECU or processor in the core network can also translate traffic from CAN/LIN bus to Ethernet
TSN bridge	The TSN bridge is in the VIU or VCU connected with a controller
