iPerf Benchmark

You can use iperf to benchmark the TCP and UDP functionality of the network stack.

TCP

Coming soon.

UDP

Assuming the default configuration the IP address of the FPGA is 10.1.212.209. On how to change the IP address of the FPGA look here.

Make sure the IP address of your testing machine is in the same subnet as the FPGA, e.g. 10.1.212.*

On the testing machine:

Download iperf 2.0.10 (you have to use this version):

wget https://netcologne.dl.sourceforge.net/project/iperf2/iperf-2.0.10.tar.gz

Unpack it:

tar xvf iperf-2.0.10.tar.gz
cd iperf-2.0.10
mkdir build && cd build
../configure
make
cd src

Load the bitstream to the FPGA.

Then on the testing machine run:

ping 10.1.212.209

You should receive ping messages from the fpga.

Then on the testing machine run:

./iperf -u -B 10.10.1.1 -s

On the FPGA board press one of the following buttons:

  • south: for a bandwidth of 1Gbps
  • center: for a bandwidth of 5Gbps
  • north: for a bandwdith of 10Gbps

Below some example measurements using two different machines. As you can see the machine is not capable to consume the data fast enough and since this runs over UDP some of the packets are dropped.

The 3 measurements are button south, center, and north.
