\subsection{Testing of SUT}
The SUT is a series of services for other computer programs with no end-user
\item Bits flipped in \emph{payload}
\begin{enumerate}
\item Correct payload
- \item Payload with even number of bits flipped
+ \item Payload with bit flips
\item Payload with odd number of bits flipped
\end{enumerate}
\item Correct or Incorrect \emph{checksum}
\item Packets received in or out of order, or missing packets
\end{enumerate}
+These partitions were chosen since they correspond to key parts of the TCP
+specification.
+
+TCP segments are send over a TCP connection from a \emph{source} to a \emph{destination port}. Therefore segments which are received which have a
+source or destination port set to an incorrect value should not be regarded
+as segments belonging to the connection.
+
+TCP uses a \emph{checksum} to catch any error introduced in headers, when this
+checksum does not match the actual computed checksum the packet should be
+disregarded.
+
+The TCP checksum is also an inherently weak one, as it is simply the
+bitwise negation of the addition in ones complement arithmetic
+of all 16 bit words in the header and data of the segment (excluding the
+header). Therefore any bit error where the ones complement value of one word
+increases by one, and the value of another decreases by one, is undetected.
+The SUT should exhibit the same behavior and accept packets where these type
+of bit error occur.

\textbf{hier iets over waarom deze partities relevant zijn! Waarom odd en
even number of bits flipped bijv interessant?}
