I need person that know SDN and use mininet and Ryu.

In SDNs I use mininet and create different topologies such as a tree, fat tree, linear, and others, connecting them with the Ryu controller to monitor flows. The switch I used is OVSK and the links are TC link with bw=0.01MBps, delay=1s, loss=50-90%, queue size=5-100packets, and use_htp=True. Also, change the used queue and Qos by “ovs-vsctl — set Port s1-eth1 qos=@newqos …..”. But when returning to the monitored flow I found that collision and Tx/Rx drop/error were always zero and did not change.
The traffic generates using continuous ping, Iperf3, and python server and clients script.
I need a dataset like the attached image that contains non-zero values for collisions and Tx/Rx drop/error monitored by the Ryu controller.
I pay for the dataset and method.
I will provide the Ryu script that monitors the flow to help you.
