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. |
| Lower layer Communication Interface module acting as a source of the L-SDU. The SrcLo is always one. | |
| Lower layer Communication Interface module acting as a destination of the L-SDU. The DstLo may by one to many. | |
| Lower layer communication interface module. | |
| Upper layer communication Interface module |
