Simple Scheduler Example

This example runs three dataplane nodes with protocol = "quic" and scheduler_type = "fifo" from examples/simple-scheduler/controller-config.toml. The included helper scripts start three UDP iperf3 server ports on node3 and launch three matching clients on node1.

From the repository root:

cd examples/simple-scheduler
docker compose build
docker compose up

In a second terminal, start the three iperf3 servers on node3:

cd examples/simple-scheduler
docker exec -it node3 /bin/bash -lc "/var/node/iperf3_s.sh"

In a third terminal, start the three clients on node1:

cd examples/simple-scheduler
docker exec -it node1 /bin/bash -lc "/var/nextmini/iperf3_c.sh"

Verify that node3 is listening on all three UDP ports:

docker exec node3 ss -lun | rg "5201|5202|5203"

You can also confirm all dataplane nodes connected:

docker exec postgres psql -U pgusr -d nextmini -c "SELECT COUNT(*) AS nodes_connected FROM nodes;"

The expected count is 3.

Shut down the example:

docker compose down
