Problems while running the program #3

Dear williehwc:

I'm a student from NCTU, Taiwan. My name is Liu. I'm interested in your rtt-p4 code and I have some problem while running the code. I followed the steps but the .csv file didn't show any information.

My command was: VM's terminal: ./controller.py -r > observed_rtts_filename.csv h1's terminal: tcpreplay -x 0.1 -i "h1-eth0" pcaps/s1-eth1_out.pcap

Am I using the wrong pcap file or there's something addtional things I need to do? The VM I use is the image uploaded by the P4 Developers(P4 Tutorial 2018-06-01.ova)

Sorry for my poor English. I appreciate your response.
