Flow_mod is one of the most important business packets. The controller send various flows to openflow switches by flow_mod, and the switch determines how to process the received service packets based on these flows.
This test will create a switch connected to a controller, through the switch, we send different rates of packet_in message to the controller, and the controller will feedback with flow_mod.
There's two content should measure:
1、The maximum flow_mod rate
2、The latency of flow_mod
We configure one hundred thousand packet_in packets on the IxNetwork and send them to the controller through different rates to analyze the flow_mod rate and latency.
The rate is in accordance with the sequence 1000、2000、3000、4000 ... ...
