A demonstation of a virtual patch between two nodes.
Topology diagram
Steps
Build the project (all examples)
cd packetcord.io
mkdir build
cd build
cmake -DENABLE_XDP_DATAPLANE=ON .. --fresh
make
Start the test deployment
cd ..
cd apps/l2_xdp_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_xdp_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

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_xdp_patch_workers/test_deployment directory, execute:
sudo ./cleanup.sh
