\chapter{\label{appendixminus1}Resources and code repositories}
The following sections describe how to acquire the resources
to reproduce the test results. All compilations were made on Ubuntu
16.04 with kernels
\begin{itemize}
\item 4.15.0-54-generic (Supporting Desktop)
\item 4.4.0-143-generic (BMV2 test VM)
\item 4.15.0-55-generic (Desktop with NetFPGA card)

\section{\label{chapterminus1:thesis:general}Master Thesis}
The master thesis including all self developed source code is
available by git via
\begin{verbatim}
git clone git@gitlab.ethz.ch:nicosc/master-thesis.git
git clone https://gitlab.ethz.ch/nsg/student-projects/ma-2019-19_high_speed_nat64_with_p4
\end{verbatim}
It can be browsed online on
\url{https://gitlab.ethz.ch/nicosc/master-thesis} and on
\url{https://gitlab.ethz.ch/nsg/student-projects/ma-2019-19_high_speed_nat64_with_p4}.

\section{\label{chapterminus1:thesis:xilinx}Xilinx Toolchain}
A prerequisite for building the NetFGPA source code is the
installation of
\begin{itemize}
\item \verb=Xilinx_SDNet_2018.2_1005_9=
\item \verb=Xilinx_Vivado_SDK_2018.2_0614_1954=
\end{itemize}
Both tools need to be installed to /opt/Xilinx/, as paths are
hardcoded in various places.

\section{\label{chapterminus1:thesis}NetFGPA support scripts}
To be able to compile P4 source code to the NetFPGA the collection of
scripts, Makefiles and sample code of P4-NetFGPA is required.

The repository \url{git@github.com:NetFPGA/P4-NetFPGA-live.git} needs
to be cloned to ``projects'' subdirectory as ``P4-NetPFGA''
of the user that wants to
compile the source code. Access to the repository is granted after
applying for access as described on
\url{https://github.com/NetFPGA/P4-NetFPGA-public/wiki}.
After that the variable \verb=P4_PROJECT_NAME= in
\texttt{~/projects/P4-NetFPGA/tools/settings.sh} needs to be modified to
read \verb|export P4_PROJECT_NAME=minip4| instead of
\verb|export P4_PROJECT_NAME=switch_calc|.
Sample code for installation:

\begin{verbatim}
  mkdir -p ~/projects
  git clone git@github.com:NetFPGA/P4-NetFPGA-live.git P4-NetFPGA
  sed -i 's/\(P4_PROJECT_NAME=\).*/\1minip4/' ~/projects/P4-NetFPGA/tools/settings.sh
\end{verbatim}
Version \textbf{v1.3.1-46-g97d3aaa} of the P4-NetPFGA repository was
used for creating the bitfiles of this project.
\begin{verbatim}
nico@nsg-System:~/projects/P4-NetFPGA$ git describe --always
v1.3.1-46-g97d3aaa
\end{verbatim}
% ok
% ----------------------------------------------------------------------
\chapter{\label{appendix0}BMV2 environment and tests}
All BMV2 based compilations were made with the following compiler:
\begin{verbatim}
p4@ubuntu:~$ p4c --version
p4c 0.5 (SHA: 5ae30ee)
\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.
% ok

%\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}

\subsection{Test 1: IPv4 egress}
Scenario: simple egress port setting for the IPv4 addresses

Step 1: getting correct values for table entries from python:

\begin{verbatim}
>>> int(ipaddress.IPv4Address(u"10.0.0.42"))
167772202
>>> int(ipaddress.IPv4Address(u"10.0.0.4"))
167772164
>>>

\end{verbatim}

Step 2: setting table netries

\begin{verbatim}

>> table_cam_add_entry realmain_v4_networks_0 realmain.set_egress_port 167772202 => 16 0 0 0 0
fields = [(u'hit', 1), (u'action_run', 3), (u'out_port', 8), (u'out_port', 8), (u'mac_addr', 48), (u'task', 16), (u'table_id', 16)]
action_name = TopPipe.realmain.set_egress_port
field_vals = [1, '16', '0', '0', '0', '0']
CAM_Init_ValidateContext() - done
WROTE 0x44020250 = 0xa00002a

READ  0x44020244 = 0x0001
success
>> table_cam_add_entry realmain_v4_networks_0 realmain.set_egress_port 167772164 => 16 0 0 0 0
fields = [(u'hit', 1), (u'action_run', 3), (u'out_port', 8), (u'out_port', 8), (u'mac_addr', 48), (u'task', 16), (u'table_id', 16)]

READ  0x44020244 = 0x0001
READ  0x44020244 = 0x0001
success
>>
\end{verbatim}

Step 3: setting arp entries

\begin{verbatim}
root@ESPRIMO-P956:~# ip neigh add 10.0.0.6 lladdr f8:f2:1e:09:62:d1 dev enp2s0f0
root@ESPRIMO-P956:~# ip neigh add 10.0.0.4 lladdr f8:f2:1e:09:62:d1 dev enp2s0f0

\end{verbatim}
Step 3: generating test packets, expecting 4 packets to show up on
enp2s0f0:

%\tvb
\begin{verbatim}
nico@ESPRIMO-P956:~$ sudo tcpdump -ni enp2s0f0
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on enp2s0f0, link-type EN10MB (Ethernet), capture size 262144 bytes

10:49:28.200445 IP 10.0.0.42 > 10.0.0.4: ICMP echo request, id 4440, seq 1, length 64
10:49:29.222340 IP 10.0.0.42 > 10.0.0.4: ICMP echo request, id 4440, seq 2, length 64

\end{verbatim}
%\tve

Result: sucess

Sometimes flashing bitfiles to the NetFPGA will fail. A random amount

A successful flashing process also emits a couple of errors, however
the message ``fpga configuration failed. DONE PIN is not HIGH'' and
its succeeding lines are missing, as seen below.

After that in all cases a reboot is required; the PCI rescan in no
tested case showed the nf devices.

\section{\label{chapterB:netpfga-nftraffic}NetFPGA misses packets on nf*}
While the nf devices appear in the operating system, packets emitted
by the netpfga cannot be sniffed on the nf interfaces
directly. Instead one has to sniff packets on a physical network card
that is connected to the specific output port.

\subsection{\label{introduction:taskdescription}The Task}
 - Milestone 1: Stateless NAT64/NAT46 translations in P4
 - Milestone 2: Stateful (dynamic) NAT64/NAT46 translations
 - Milestone 3: Hardware adaption

This thesis is
into 3 milestone
P4 environment
a lot of potential
Programming language in the network
Not only faster, but also more convienient.

**** High speed NAT64 with P4
 Currently there are two main open source NAT64 solution available:
 tayga and jool. The former is a single threaded, cpu bound user
 space solution, the latter a custom Linux kernel module.

 This thesis challenges this status quo by developing a P4 based
 solution supporting all features of jool/tayga and comparing the
 performance, security and adaptivity of the solutions.


Describe your task.


\begin{verbatim}

***** Motivation zeigen
***** IPv6, NetPFGA mehr Möglichketien
***** P4 erwähnen
***** Task gut zu zeigen,  alles erreicht
