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} .
2019-08-19 23:29:26 +00:00
After that the variable \texttt { P4\_ PROJECT\_ NAME} in
2019-08-04 10:58:17 +00:00
\texttt { ~/projects/P4-NetFPGA/tools/settings.sh} needs to be modified to
2019-08-19 23:29:26 +00:00
read \texttt { export P4\_ PROJECT\_ NAME=minip4}
instead of \texttt { export P4\_ PROJECT\_ NAME=switch\_ calc} .

\section { \label { appendix:netfpga:compile} P4/NetFGPA compilation process}
After having setup the compile host as described above, the script
\texttt { bin/do-all-steps.sh} that is included in the thesis' git
repository. With a NetFPGA card installed in the host, this script
will compile the P4 source code to PX and in a second step to HDL and
then upload the resulting bitstream to the NetFPGA. The compilation
process will log its output to the directory
\texttt { \~ /master-thesis/netpfga/log/} .

\subsection { Test 1: IPv4 Egress}
In this test we test whether setting the output port based on the
IPv4 address.
First we get the integer values of the IPv4 addresses in python:
2019-07-31 08:50:30 +00:00
\begin { verbatim}
>>> int(ipaddress.IPv4Address(u"10.0.0.42"))
167772202
>>> int(ipaddress.IPv4Address(u"10.0.0.4"))
167772164
>>>
\end { verbatim}
2019-08-19 23:29:26 +00:00
After that we set the table table entries for the NetFPGA.
2019-08-21 14:22:47 +00:00
\begin { tiny} \begin { verbatim}
2019-07-31 08:50:30 +00:00

2019-08-19 23:29:26 +00:00
On the host we setup the ARP entries:
2019-08-21 14:22:47 +00:00
\begin { tiny} \begin { verbatim}
2019-07-31 08:50:30 +00:00

2019-08-21 14:22:47 +00:00
\end { tiny}
2019-08-19 23:29:26 +00:00
And then we generate test packets and expect 4 packets to show up on
enp2s0f0.
The following \texttt { tcpdump} output shows the expected packets
arriving on enp2s0f0:
2019-08-21 14:22:47 +00:00

\subsection { Test 2: IPv6 egress}
2019-08-19 23:29:26 +00:00
This test shows how setting the egress port based on the IPv6 address
works with the NetPFGA. Similar to the previous test, we first the
the Integer values of the IPv6 addresses:
2019-07-31 09:30:56 +00:00
\begin { verbatim}
>>> int(ipaddress.IPv6Address(u"2001:db8:42::4"))

2019-08-19 23:29:26 +00:00
After that we set the table entries:

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.
2019-08-19 23:29:26 +00:00
After that in all cases a reboot is required; the PCI rescan in none
of our test cases re enabled the nf devices.

\section { \label { benchmark:tayga} Tayga}
Tayga is installed from the regular package database:
\begin { verbatim}
ii tayga 0.9.2-6 amd64 userspace stateless NAT64
\end { verbatim}
We prepare the networking as follows:
\begin { verbatim}
[15:12] nsg-System:~# ip addr add 10.0.0.77/24 dev eth1
[15:12] nsg-System:~# ip l s eth1 up
nico@ESPRIMO-P956:~$ ~ / master - thesis / bin / init _ ipv 4 _ esprimo.sh

#!/bin/sh
2019-08-13 10:56:15 +00:00
2019-08-19 23:29:26 +00:00
sudo ip addr add 10.0.0.42/24 dev enp2s0f0
sudo ip link set enp2s0f0 up
2019-08-13 10:56:15 +00:00
2019-08-19 23:29:26 +00:00
nico@ESPRIMO-P956:~$ sudo ip route add 10 . 0 . 1 . 0 / 24 via 10 . 0 . 0 . 77
\end { verbatim}
And verify that networking works:
\begin { verbatim}
[15:12] nsg-System:~# ping 10.0.0.42

\end { verbatim}
2019-08-19 23:29:26 +00:00
We also setup the IPv6 networking:
2019-08-21 14:22:47 +00:00
\begin { tiny} \begin { verbatim}

2019-08-21 14:22:47 +00:00
\end { tiny}
2019-08-19 23:29:26 +00:00
And verify that IPv6 networking works:
2019-08-13 10:56:15 +00:00
\begin { verbatim}
2019-08-19 23:29:26 +00:00

2019-08-13 10:56:15 +00:00
\end { verbatim}
2019-08-19 23:29:26 +00:00
We enable IPv6 and IPv4 forwarding:
\begin { verbatim}
[15:16] nsg-System:~# sysctl -w net.ipv6.conf.all.forwarding=1
net.ipv6.conf.all.forwarding = 1
2019-08-13 10:56:15 +00:00
2019-08-19 23:29:26 +00:00
[15:20] nsg-System:~# sysctl -w net.ipv4.ip_ forward=1
net.ipv4.ip_ forward = 1
\end { verbatim}
And we test NAT64 with tayga:

\section { \label { benchmark:jool} Jool}
We install Jool 4.0.1 from source from
\url { https://www.jool.mx/en/download.html} as follows:
2019-08-21 14:22:47 +00:00
\begin { tiny}
2019-08-19 23:29:26 +00:00

nico@nsg-System:~/jool-4.0.1$ sudo make install
\end { verbatim}
2019-08-21 14:22:47 +00:00
\end { tiny}
2019-08-19 23:29:26 +00:00
We enable forwarding:
\begin { verbatim}
sysctl -w net.ipv4.conf.all.forwarding=1
sysctl -w net.ipv6.conf.all.forwarding=1
\end { verbatim}
We configure jool to map the network prefixes and setup iptables to
redirect the traffic into the jool instance:
2019-08-21 14:22:47 +00:00
\begin { tiny}
2019-08-19 23:29:26 +00:00

2019-08-21 14:22:47 +00:00
\end { tiny}
2019-08-19 23:29:26 +00:00
Afterwards we test NAT64:
