I am developing an algorithm to solve the rule placement problem in SDN , and I want to compare my algorithm with already-proposed . In order to do that, I want to conduct a simulation for geting rules placement as dataset(extract and reuse of rules as dataset than analzying them with an algorithm ) from tableflow in mininet . However, I am not sure which simulation environment to use . Any help and i will be appreciated.
You can use the mininet network emulator to create a topology based on OpenVSwitch. Then you can select from amongst popular SDN controllers such as POX, Ryu, Floodlight, OpenDaylight, ONOS etc.
Some controllers like ONOS have APIs you can use to query the flow-table state at the controller, while in others (like POX), you will have to write your own module.
However, the ovs-ofctl commands of OpenVSwitch, like dump-flows can be used to query the flow-table at the switches. You can find the documentation of ovs-ofctl here.
