NAME

dtpcd - DTPC daemon task for receiving and processing DTPC ADUs in bundles

SYNOPSIS

dtpcd

DESCRIPTION

dtpcd is a background "daemon" task that manages the reception and processing of DTPC
protocol data units. It receives the payloads of bundles destined for the "ipn"-scheme
endpoint whose node number is the number of the local node and whose service number is the
DTPC_RECV_SVC_NBR (129 as of the time of this writeng).

DTPC 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 ADU. Each ADU is parsed into its constituent application data items,
which are then delivered to the applications awaiting them, and when required a DTPC end-
to-end acknowledgment PDU is returned to the DTPC PDU sender.
