2019-08-04 09:37:06 +00:00
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.

2019-08-04 09:37:06 +00:00
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

All BMV2 based compilations were made with the following compiler:
\begin{verbatim}
p4@ubuntu:~$ p4c --version
p4c 0.5 (SHA: 5ae30ee)

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.

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.

\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
