Dear All,
I am running apache2 server in one of the mininet host (ip:10.0.0.1) and
trying to streaming the video in the other two other hosts (ip: 10.0.0.3
and 10.0.0.4). All the hosts are connected with a single switch. I want
to have a queue for tcp flows going to 10.0.0.3. The rest I followed the
1st example of QoS chapter of Ryu book. I am using this python code
right now (written by myself) to set the queues however, though the
controller say queue is successful, when I stream the video it doesn't
work. The python file is attached. Thanks for the help.
