Trying to run the example provided in: https://doc.dpdk.org/guides/sample_app_ug/skeleton.html

The functionality is pretty straightforward → it pairs the port in such a way that the data from port 1 is transmitted to port 2, and from port 2 is transmitted to port 1. If there are port 3 and 4, it will manage the exchange of data between them.

But to achieve this, we need to bind ports to DPDK.

Creating the experiment profile

Used the 3-node-setup-using-docker as a reference and created this experiment profile of small-lan nodes running Ubuntu 22.04.

profile urn: https://www.cloudlab.us/p/d303a9844401debd1bacbf0f797c14a560d937ea

Instantiated the profile on c220g2

Setting up DPDK

ref: Installing DPDK and running the helloworld application

  1. ssh'd into the node
  2. sudo apt-get update
  3. Installed required packages
sudo apt-get install python3-pip build-essential libnuma-dev pkgconf meson ninja-build python3-pyelftools
  1. Check number of nodes and allocate hugepages
lscpu | grep "NUMA node(s)"

ls /sys/devices/system/node/  | grep node
