Steps to reproduce measurements
The setup and experiment execution for the worst-case measurements of DPDK-l2fwd (HW/VM) evaluation is part of the description for Table II.
Steps to reproduce figures
Raw data
Pcaps (DPDK-l2fwd (HW), DPDK-l2fwd (VM))
Evaluation execution
Setup evaluator
# install dependencies
apt install postgresql postgresql-client parallel python3-pip texlive-full zstd
python3 -m pip install pypacker
