Steps

Build the project (all examples)

cd packetcord.io
mkdir build
cd build
cmake -DENABLE_DPDK_DATAPLANE=ON .. --fresh
make

Start the test deployment

cd ..
cd apps/l2_dpdk_patch_workers/test_deployment/
sudo ./deploy.sh

Go to the shell of Patch

docker exec -it patch /bin/sh

Inside the container, run the following commands and leave the shell open:

cd /root
./l2_dpdk_patch_workers_app

Result

Open the shells of Node A and Node B. Try to ping each other (172.16.111.1 and 172.16.111.2).

docker exec -it node_a /bin/sh

docker exec -it node_b /bin/sh

64 bytes from 172.16.111.1: seq=3 ttl=64 time=0.040 ms

Let's also run iperf3 between Node A (server) and Node B (client):

On Node A

iperf3 -s

On Node B

iperf3 -c 172.16.111.1

Destroy the test deployment

Close all container shells. On the host, inside the l2_dpdk_patch_workers/test_deployment directory, execute:

sudo ./cleanup.sh
