Query: Identifying Packet Loss and Reordering Packets in Keyed UDP
  Transmissions   The User Datagram Protocol (UDP) and other similar protocols send the
application data from the source machine to the destination machine inside
segments, without foreseeing nor allowing for any type of control on the
transmission or success metrics. These protocols are very convenient for e.g.
real time data transmission. But when the reliability of the transmitted data
is critical, other protocols termed as connection-oriented, allow for full
control of the data transmission process, assuring that the received data is an
exact copy of the transmitted data, e.g. the case of the Transmission Control
Protocol (TCP). To sustain the increased functionality and features of the
connection-oriented protocol, a set of mechanisms is implemented based on some
specific fields of the segment header. These mechanisms result in a significant
overhead in terms of the increased number of transmitted packets. This may
further translate into significant delays, because of the additional number of
switching and routing tasks, and eventually, because of more complex
communications procedures, such as e.g. transmission window resizing, and of
course, acknowledgement and sequence numbers updating. The two extremes of
these communication modalities, one that has no control at all, and the other
one that allows for full control, have resulted in the creation of an
intermediate protocol that allows for a limited degree of knowledge on how
successful a transmission was, and even for an eventual reordering of the
segments that arrive out of sequence. This paper presents simulation results
that confirm the efficiency of the new almost-reliable UDP protocol, termed
Keyed User Datagram Protocol (or KUDP) for transmission of data that includes
the ability to identify which packets were lost and to reorder packets that
were received out-of-sequence, and points future tasks to be pursued in this
research.
