Generating PCAP and Flows

OF_BRIDGE="tcp:67.17.206.196:9933"
OVERHEAD=4
OF_INTF="eth2"
ACTION="output:4"

a. Download scripts

https://github.com/jab1982/openflow-accuracy-measurement.git

b. Generating 500 flows with 500 packets each. All flows are considered “generic” (no input port) and the only action is to forward to port 4 (sink server)

python tracegen.py -t -4 -m 500 -n 500 --actions $ACTION -o sink_output.pcap

c. Validating results

ovs-ofctl -OOpenFlow13 add-flows $OF_BRIDGE sink_output.pcap.flows

tcpreplay -i $OF_INTF -p 10000 sink_output.pcap

ovs-ofctl -OOpenFlow13 dump-flows $OF_BRIDGE > sink_output.pcap.dump-flows-of13

python validate.py -t sink_output.pcap.truth -m sink_output.pcap.dump-flows-of13 -b $OVERHEAD

ovs-ofctl -OOpenFlow13 del-flows $OF_BRIDGE
