How to craft specific packets on the host of Mininet to generate massive Packet-In messages

I am wondering that how to generate massive packet-in messages to the controller to test the response time of SDN controller in the environment of Mininet.

Can you give me some advice on it?

You could use iperf to send packets, like this: 

$ iperf -c -F

You could specify the amount of time:

$IPERF_TIME (-t, --time)

The time in seconds to transmit for. Iperf normally works by repeatedly sending an array of len bytes for time seconds. Default is 10 seconds. See also the -l and -n options.

Here is a nice reference for iperf: https://iperf.fr/.

If you would like to use Scapy, try this:

from scapy.all import IP, TCP, send

data = "University of Network blah blah"
a = IP(dst="129.132.2.21")/TCP()/data
send(a)
