Figure 2-6: Pipe Diagram—Extended Procedure<br />
This subsection contains sequence diagrams that illustrate how the protocol uses data<br />
transmission <strong>and</strong> protocol control PDUs to implement the various options available in the<br />
unreliable <strong>and</strong> reliable services. Table 2-2 defines the abbreviations used in the figures for<br />
various PDU types; the protocol definition in reference [1] defines the meaning <strong>and</strong> format of<br />
these PDUs in detail. In each file delivery operation, the sequence of events between the file<br />
sender <strong>and</strong> the file receiver is as shown.<br />
