Run the docker image with p4c compiler and nikss-ctl installed:

docker run -it --privileged --rm -v "$(pwd)":/nikss osinstom/nikss

Whole demo runs inside that container, so every later command must be executed in the container, e.g. prepended with docker container exec -it <container_name>.

Boot up the demo infrastructure:

make start

The above script will create 4 Linux namespaces: switch, client, server1, server2.

Compile the P4 program (replace path to p4c repository):

make compile

Deploy PSA-eBPF program and insert eBPF programs with forwarding rules (no virtual IP yet):

make deploy

Set up rules for load-balancing and server virtual IP address:

make load-balancer

Run HTTP servers, one in every container. Issue these commands, every in separate terminal:

make http-server-1
make http-server-2

Run client, which makes some requests to the server(s) on virtual IP:

make http-client

This should take about 20 second to execute. When client stops, stop servers with Ctrl-C to see number of processed requests per server.

Disaable load-balancer and remove virtual IP:

make stop-load-balancer

Set up a meter rule:

make rate-limiter

Run iperf server on server no. 1:

make iperf-server

Run iperf client and observe results:

make iperf-client

To remove meter rule:

make stop-rate-limiter

Configure traffic manager (tc qdisc) with QoS classes and treatment.

make configure-traffic-manager

Start ping between client and server1:

make ping

Create congestion on the link between client and server1:

make iperf-server
make iperf-client

Set priority for ICMP traffic:

make set-priority

Clear priority for ICMP traffic:

make clear-priority
