# Terms
|Short Name(Abbreviation / Acronym)|Description|
|:--|:--|
PDU|Protocol Data Unit.
I-PDU|Interaction Layer PDU. An I-PDU consists of data (buffer), length and I-PDU ID.
I-PDU ID|I-PDU Identifier.
L-PDU|Data Link Layer PDU. One or more I-PDUs are packed into one L-PDU. The L-PDU is bus specific, e.g. Ethernet frame.
L-PDU ID|L-PDU Identifier.
SDU|Service Data Unit.
L-SDU|Data link layer service data unit. An L-SDU consists of data(buffer), length, L-SDU ID and may L-PDU specific information transported via meta data.
L-SDU ID|L-SDU identifier
L-SDU Router|Module that transfers L-SDUs from one module to another module. The L-SDU Router module can be utilized for internal routing purposes.
Upper Layer Modules (Up)|Modules above the L-SDU Router. This layer usually includes IEEE1722Tp.
Lower Layer Modules (Lo)|Modules below the L-SDU Router. This layer includes the Ethernet Communication Interface module.
<SrcLo>|Lower layer Communication Interface module acting as a source of the L-SDU. The SrcLo is always one.
<DstLo>|Lower layer Communication Interface module acting as a destination of the L-SDU. The DstLo may by one to many.
<Lo>|Lower layer communication interface module.
<Up>|Upper layer communication Interface module
