I have used all opendaylight, floodlight and POX controllers one by one in my SDN ring topology which is created by mininet, but I am not able to use traceroute command and trace the paths where the ping packets transferred.
In this article
SDN Traceroute: Tracing SDN Forwarding Without Changing Network Behavior
it is said that they have created a method to traceroute the SDN, but it is so hard to apply.
any other suggestion?
