the question of the performance of ccp-bbr in Pantheon

[jialianchen]

Hello,I want to test the performance of ccp-bbr in Pantheon.but i meet some question.
i open the ccp-bbr using sudo ./target/debug/bbr --ipc netlink,
and use the ccp.py in pantheon/src/wrappers

#!/usr/bin/env python

from subprocess import check_call

import arg_parser


def main():
    args = arg_parser.receiver_first()

    if args.option == 'deps':
        print 'iperf'
        return

    if args.option == 'receiver':
        
        cmd = ['iperf', '-s', '-p', args.port]
        check_call(cmd)
        return

    if args.option == 'sender':
        cmd = ['iperf', '-c', args.ip, '-p', args.port,'-i','1','-Z','ccp',
               '-t', '75']
        check_call(cmd)
        return


if __name__ == '__main__':
    main()

i test the local mode in Pantheon,but i get confused output.
pantheon_report.pdf

and it is my output in terminal.

I wonder what should i do if i want to test the algorithm in Pantheon.
thanks for your help!

Hi,
It seems you are using linux 4.15 with pantheon. I would suggest using the latest version of ccp-kernel and a newer Linux, e.g. 5.4.

Also, the master branch of pantheon doesn't have any ccp.py in src/wrappers/ (https://github.com/StanfordSNR/pantheon/tree/master/src/wrappers). Are you working off a fork of the repo, or is this code you added or something? Could you point us to the ccp.py you're referring to?

Either way, ccp seems to be running properly, so it seems the issue is more with the bbr algorithm performing poorly.

Can you tell us more about what you're trying to do? What are you using pantheon for in particular? What link is this?
