\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
|
|
\end{itemize}
|
|
|
|
\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
|
|
\end{verbatim}
|
|
|
|
It can be browsed online on \url{https://gitlab.ethz.ch/nicosc/master-thesis}.

\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}
|
|
|
|
% ----------------------------------------------------------------------
|
|
\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.
|
|
|
|
\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}

Majority of the log files are stored inside the source code directory

stored at ``netpfga/logs''. It follows a selection of log files
|
|
|
|
\section{\label{chapterB:netpfga-flasherror}NetFPGA Flash Errors}
|
|
Sometimes flashing bitfiles to the NetFPGA will fail. A random amount
|
|
of reboots (1 to 3) and a random amount of reflashing will fix this
|
|
problem.
|
|
|
|
Below can be found the log output from the flashing process.

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.

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.

\begin{verbatim}
|
|
checking for library containing argp_parse... none required

|
checking for pkg-config... /usr/bin/pkg-config

configure: error: Package requirements (xtables) were not met:

|
|
|
|
Consider adjusting the PKG_CONFIG_PATH environment variable if you
|
|
installed software in a non-standard prefix.
|
|
|
|
Alternatively, you may set the environment variables XTABLES_CFLAGS
|
|
and XTABLES_LIBS to avoid the need to call pkg-config.
|
|
See the pkg-config man page for more details.

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.
