Hi Daniel,
Our switches supports OpenFlow 1.0, we did not check especially with Open Daylight beside doing some foo-foo tests.
Defense4All redirects traffic to an AMS (Radware’s DefensePro AMS) which cleans the traffic. Do you have the AMS appliance in your setup?
How many hosts do plan to protect agianst the DDOS? This affects the number of flows being monitored by Defense4All .
Do you know where Defense4All collects the flow statistics from? Does it install flows in the physical switches or in the edge (i.e. open vswitch)?
w/o knowing these details it would be hard to predict.
Regards,
Alon
