 \subsection{\GAST}
 
+Since \GAST requires a input enabled model, the actual specification is a bit different compared to the other tools.
+Luckily \GAST is capable of generating a graphical representation of the model from source.

+Because of the input enabled model it was necessary to include the \emph{ConnectionError} state. 
+All inputs (packets sent from \emph{SUT}) which the original TCP specification 
+deems illegal in a given state are redirected 
+to this state which is also defined as one of the final states together with \emph{Closed}.
+When \GAST will end up in this state the SUT is reset and a new path is tried.
+
+Because of time constraints we decided to allow \GAST to evaluate $9000$ paths.
+None of the paths where rejected by \GAST. The output generated by \GAST is listed below.
