 analyzed and validated according to the \textit{RFC793} specification. 
 The valid packets are build manually from the \textit{RFC793} specification. 
 Invalid packets are generated from this valid traffic using Bit-Twist. 
 The boundary values for the different parameters (fields in packets) are determined by hand. Automated scripts are used in order to generate packets with some fields replaced with these
 \emph{boundary values}.
