Data output, instance 2
The data integrity of each individual UDP datagram is ensured with the UDP checksum.
The UDP neither ensures the arrival, nor the sequence, nor protection from duplicates.
Therefore each UDP datagram is complemented with an additional 24-byte header for
data output see table 1, page 14. Using the information in this header, the receiver
can recognize duplicates and the loss of datagrams, redo the sequence and re-combine
the (possibly fragmented) instances of the data output. As UDP does not offer the
opportunity to re-request lost datagrams, receivers must be able to deal with data loss.
