Description

      Packet_out is one of the most important content of SDN controller. It is the most frequent message between the controller and the openflow switch.

      This test will create a switch connected to a controller, through the switch, we send different rates of packet_in message to the controller to measure the controller's processing power of packet_in.

      There's two content should measure:

      1、The maximum packet_out rate

      2、The latency of packet_out

      We configure one million packet_in packets on the IxNetwork and send them to the controller through different rates to analyze the packet_out rate and latency.

      The rate is in accordance with the sequence 5000、10000、15000、20000 ... ...
