Steps to reproduce measurements

The setup and experiment execution for the worst-case measurements of DPDK-l2fwd (HW/VM), Snort-fwd (HW/VM), and Snort-filter (HW/VM) evaluation is part of the description for Figures 3, 5, and 6. The respective explanation for the RT kernel can be found here

Steps to reproduce figures

Raw data

Pcaps (DPDK-l2fwd (HW), DPDK-l2fwd (VM), Snort-fwd (HW), Snort-fwd (VM), Snort-filter (HW), Snort-filter (VM))

Evaluation execution

Setup evaluator 

# install dependencies
apt install postgresql postgresql-client parallel python3-pip texlive-full zstd
python3 -m pip install pypacker

Generate figures 

git clone https://github.com/gallenmu/hipnet21 /root/hipnet21

#decompress pcaps
cd /root/hipnet21
for i in $(find . -iname *.zst); do zstd --rm -d $i; done;

#create figures
# MPATH = dpdk-l2fwd | snort-fwd | snort-filter
# MODE = vm | hw
# RATE = 10000, 20000 ... 120000
