If my designated controller succeeded to ping between two hosts, is it possible to make TCP connection between them via Mininet? I did mininet>h0 ping h4 successfully but pinging is just ICMP packets not TCP!!
Thank you
If the ping was ok you can try iperf which will test bandwidth over TCP (read here https://github.com/mininet/mininet/wiki/Bufferbloat#part-3-streaming-video---sketch-the-tcp-cwnd-and-buffer-occupancy) You could also try to setup a simple http server on mininet on some host which will stand over TCP.
mininet> h1 python -m SimpleHTTPServer 80 &
mininet> h2 wget -O - h1
Both of the above should work and give you TCP connections
