This use case is composed of three virtual functions (VFs) running in separate Ubuntu Virtual Machines:
- Packet generator: Sends packets to the packet sink through the firewall. This includes a script that periodically generates different volumes of traffic.
- Firewall: Reports the volume of traffic passing though to the ONAP DCAE collector.
- Traffic sink: Displays the traffic volume that lands at the sink
VM using the link http://192.168.20.250:667 through your browser and enable automatic page refresh by clicking the "Off" button. You can see the traffic volume in the charts.
The packet generator contains 10 streams: fw_udp1, fw_udp2, fw_udp3, . . . , fw_udp10. Each stream generates 100 packets every 10 seconds. The /opt/run_traffic_fw_demo.sh script on the packet generator VM starts automatically and alternates high traffic (i.e. 10 active streams at the same time) and low traffic (1 active stream) every 5 minutes.
To enable a stream, include {"id":"fw_udp1", "is-enabled":"true"}
in the pg-stream bracket.
To adjust the traffic volume produced by the packet generator, run the following command in a shell:
curl -X PUT \
-H "Authorization: Basic YWRtaW46YWRtaW4=" \
-H "Content-Type: application/json" \
-H "Cache-Control: no-cache" \
-d '{"pg-streams":{"pg-stream": [{"id":"fw_udp1", "is-enabled":"true"},{"id":"fw_udp2", "is-enabled":"true"},{"id":"fw_udp3", "is-enabled":"true"},{"id":"fw_udp4", "is-enabled":"true"},{"id":"fw_udp5", "is-enabled":"true"}]}}' \
"http://192.168.10.200:8183/restconf/config/sample-plugin:sample-plugin/pg-streams"The command above enables 5 streams.
