   1 \subsection{Objectives}
   2 %1, 2
   3 The objective of this document is to provide an approach for testing a
   4 particular implementation of \textit{Transmission Control Protocol} (TCP). TCP
   5 is a host-to-host protocol that provides a reliable communication.
   6
   7 This testing approach can be used by either an internal test team or an
   8 independent testing team. The test effort's goal is to become confident about
   9 the conformance of the implementation to the specification created by
  10 \textit{The Internet Engineering Task Force}
  11 (IETF)\footnote{\url{http://www.ietf.org}} as document
  12 \textit{RFC793}~\cite{rfc793}.

  14 \subsection{SUT}
  15 %3,4
  16 The \textit{System under test} (SUT) is a
  17 Java\footnote{\url{http://www.java.com}} TCP driven echo server that executed
  18 on a virtualized Ubuntu system\footnote{\url{http://www.ubuntu.com}} running on
  19 the Linux kernel\footnote{\url{http://www.kernel.org}} version $3.13$. To test
  20 the error behaviour custom iptables output policies have to be
  21 set Listing~\ref{listing:iptables}. This is needen because the OS by default
  22 closes all connections from unknown sources and the manually created TCP
  23 connections used in testing the implementation are unknown to the OS.
