scalability of NAT64 on programmable switches. a software emulated switch was created that translates IPv4 to IPv6 and vice versa.
Due to the target independence of P4 the same code can be compiled
for and deployed to on the FPGA hardware platform ``NetFPGA''.
Within the NetFPGA the NAT64 implementation achieves a stable throughput of
9.29 Gigabit/s and allows in network translations without a router.

%% Well this section can be further subdivided into subsection. We present
%% this in subsection \ref{chapter2:essentials:subsections}.
%% \subsection{\label{chapter2:essentials:subsections}Subsections}
%% \paragraph{\label{introduction:essentials:subsections:paragraph}Paragraphs}
%% can be specially referenced as well.
%% Of further importance is the understanding of the following environments:
%% %*** itemized lists
%% \begin{itemize}
%% \item This shows an itemized bullet list
%% \begin{itemize}
%% \item Which can be used for several levels\ldots
%% \end{itemize}
%% \end{itemize}
%% %*** enumerated lists
%% \begin{enumerate}
%% \item The same applies to enumerated lists.
%% \end{enumerate}
%% %** figures
%% \begin{figure}[!hbt]
%% \begin{center}
%% % \includegraphics[width=\textwidth, angle=90]{file_name.eps}
%% \caption{This is a figure to be printed in a float}
%% \label{file_name}
%% \end{center}
%% \end{figure}
%% By figure \ref{file_name}, we show some funny figures.
%% Table with caption and footnotes below the table.
%% \begin{table}[htbp]
%% \begin{center}\begin{minipage}{\textwidth}
%% \begin{tabular}{| c | p{130pt} | l |}
%% \hline
%% Column 1 & Column 2 \newline (additional line) & Column 3 \\

%% Examples of different text sizes:
%% \small Small \\
%% \scriptsize Script size \\
%% \normalsize Normal \\
%% \large Large \\
%% \huge Huge \\
%% \normalsize
%% \CHECK
%% If we reference to another document, we cite the document \cite{Lamport:LaTeX}.
%% %** landscape
%% \NEW
%% \begin{landscape}
%% Of some interest is also the landscape environment:

%% Even though we don't think full listings are useful in documents,
%% you can easily insert complete files by the verbatiminput{}-command.
