There are a variety of possible network layouts for realising
NAT64. In this thesis two different layouts where taken into account:
routed translation and transparent in network translation.

\section{\label{chapter0:bmv2-diff}Diff based checksumming} All BMV2 based compilations were made with the following compiler:
\begin{verbatim} \begin{verbatim}
p4@ubuntu:~$ p4c --version
p4c 0.5 (SHA: 5ae30ee)
\end{verbatim} \end{verbatim}
The installation is based on the vagrant files that were provided in
the
``Advanced Topics in
Communication Networks Fall 2018'' course of
ETHZ (\url{https://adv-net.ethz.ch/2018/}) and contains p4tools as
well as all utilities that came with the vagrant installation.
\section{\label{chapter0:bmv2-diff}Diff based checksumming}
For running the diff based checksum code, the following steps are
necessary:
Compiling the p4 code and starting the switch:
\begin{verbatim}
cd ~/master-thesis/p4app
sudo p4run --config nat64-diff.json
\end{verbatim}
Starting the controller which sets up the required table entries:
\begin{verbatim}
cd ~/master-thesis/p4app
sudo python ./controller.py --mode range_router
\end{verbatim}
