用語(terms)

Term	Description
Upper Layer Modules(Up)	Modules above the PDU Router. This layer usually includes Com and Diagnostic Communication Manager (Dcm).
Lower Layer Modules(Lo)	Modules below the PDU Router. This layer may include CAN, LIN, FlexRay, Ethernet Communication Interface modules and the respective TP modules.
PDU Router	Module that transfers I-PDUs from one module to another module. The PDU Router module can be utilized for gateway operations and for internal routing purposes.
on-the-fly gatewaying	Gateway capability; routing between two TP modules where forwarding of data is started (when a specified threshold is reached) before all data have been received. If larger amount of data is transported between two interfaces it is desirable to be able to start the transmission on the destination network before receiving all data from the source network. This saves memory and time.
multicast operation	Simultaneous transmission of PDUs to a group of receivers, i.e. 1:n routing.
data provision	Provision of data to interface modules. (a) direct data provision: data to be transmitted are provided directly at the transmit request. The destination Communication Interface may behave in two ways, either copy the data directly or defer the copy to a trigger transmit. (b) trigger transmit data provision: data to be transmitted are not provided at the transmit request, but will be retrieved by the Communication Interface module via a callback function.
last-is-best buffering	Buffering strategy where the latest value overwrites the last value.
FIFO buffering	Buffer concept, which uses first in first out strategy.
I-PDU ID	I-PDU Identifier.
I-PDU	Interaction Layer PDU. An I-PDU consists of data (buffer), length and I-PDU ID. The PDU Router will mainly route I-PDUs (exception is on-the-fly gatewaying).
N-PDU	Network Layer PDU. Used by Transport Protocol modules to fragment an I-PDU.
L-PDU	Data Link Layer PDU. One or more I-PDUs are packed into one L-PDU. The L-PDU is busspecific, e.g. CAN frame.
SF	Single Frame, Transport Protocol term.
FF	First Frame, Transport Protocol term.
CF	Consecutive Frame, Transport Protocol term.
PDU	Protocol Data Unit.
BSW	Basic Software.
	Lower layer Communication Interface module acting as a source of the I-PDU. The SrcLo is always one.
	Lower layer Communication Interface module acting as a destination of the I-PDU. The DstLo may by one to many.
	Lower layer Transport Protocol module acting as a source of the I-PDU. The SrcLoTp is always one.
	Lower layer Transport Protocol module acting as a destination of the I-PDU. The DstLoTp may by one to many.
	Lower layer communication interface module.
	Upper layer Communication Interface and/or Transport Protocol module.
	Lower layer Transport Protocol module.
	Any type of module <...>.
