#P4RCProbe ![P4RCProbe]
We present the platform-independent and flexible SDN Controller Analysis Tool P4RCProbe, an extension of OFCProce, on this website. It features a scalable and modular architecture that allows a granular and deep analysis of the controllers behaviors and characteristics. OpenFlow and P4Runtime controllers can be pushed to their limit and the bottlenecks can be investigated. The tool allows the emulation of virtual switches that each provide sophisticated statistics about the controller behavior.
- Download and install Maven
- Make sure that your Maven setup allows new repositories
- Execute
mvn packageto download dependencies and compile OFCProbe. - The result can be found in
target/p4rcprobe-*.one-jar.jar. - Command:
java -jar target/p4rcprobe-*.one-jar.jar demo.ini
- Java 7
- OpenFlow or P4Runtime (Only ONOS) Controller
- Preferably a Linux System (Shell Scripts + Screen Usage in Scripts provided)
- Passwordless SSH-Connection between OF Controller Host and P4RCProbe Host for User openflow
- Optional: SNMP Server on Controller Host (for CPU and RAM Utilization of OF Controller Host)

Example for NormalDistribution, mean = 10, stdev=5:
- trafficGenConfig.iatType = 1
- trafficGenConfig.iatDistribution = Normal
- trafficGenConfig.iatDistributionParamter1 = 10
- trafficGenConfig.iatDistributionParamter2 = 5
- Set config.checkForIndividualSwitchSettings = true in config.ini on OFCProbeHost
- Check ofSwitch.ini and change it
- Allows to change IAT, fillThreshold, start- and stopDelay, PCAP file and Distribution Settings
- If pcapFile Options is set, this specific ofSwitch will only send OF_PACKET_INs with Payloads sequentially taken from that PCAP File (File will be looped)
