Introduction

The official source code of the paper Scaling Open vSwitch with a Computational Cache (USENIX NSDI, 2022).

This repo contains:

Reproducing the results

Connect two machines back-to-back using DPDK supported NICs. The machines should also be connected to a shared LAN (e.g., via another NIC). This is essential for running the scripts. The System Under Test (SUT) machine must have an Intel CPU that supports both the AVX and POPCNT extensions. You must have a Linux OS with root permissions in both machines for building the environment. Contact me for a link to the ruleset artifacts, or create one of your own using these tools.

SUT machine

Run sudo ./build-sut.sh. This script downloads the relevant DPDK and OVS versions, installs libnuevomatchup, patches and compiles OVS, and installs it.

Load Generator (LGEN) machine

Run sudo ./build-lgen.sh. This scripts downloads our custom made packet generator.

Running the experiments

Run sudo ./scripts/run-experiments.sh sut on the SUT machine. The script will wait for instructions from the LGEN machine.

Run sudo ./scripts/run-experiments.sh lgen NAME on the LGEN machine, where NAME is the experiment name to run, such as thr-caida-3m.
