It receives the payloads of bundles destined for the \*(L"ipn\*(R"\-scheme endpoint whose node number is the number of the local node and whose service number is the \s-1DTPC_RECV_SVC_NBR \&\s0(129 as of the time of this writeng). .PP \&\s-1DTPC\s0 protocol data units are of two types: application data units (ADUs, i.e., aggregations of application data items) and acknowledgments. Each acknowledgment is interpreted as authorization to release the buffer space occupied by the node's local copy of the acknowledged \s-1ADU. \s0 Each \s-1ADU\s0 is parsed into its constituent application data items, which are then delivered to the applications awaiting them, and when required a \s-1DTPC\s0 end-to-end acknowledgment \s-1PDU\s0 is returned to the \s-1DTPC PDU\s0 sender. .SH "EXIT STATUS" .IX Header "EXIT STATUS" .ie n .IP "0" 4 .el .IP "\f(CW0\fR" 4 .IX Item "0" \&\fBdtpcd\fR terminated normally, for reasons noted in the \fBion.log\fR file.
