Demonstrations of mptcpify, the Linux eBPF/bcc version.


mptcpify forces the application to use to MPTCP instead of TCP.

mptcpify has been verified with iperf3 and rsync[TCP module]. It can be used
for incresing the speed of transferring data with rsync.

The MPTCP configuration is decribed in
https://www.mptcp.dev/pm.html

USAGE message:

usage: sudo python ./mptcpify.py [-h] [-t TARGETS]

mptcpify try to force applications to use MPTCP instead of TCP

options:
  -h, --help            show this help message and exit
  -t TARGETS, --targets TARGETS
                        use ',' for multi targets, eg: 'iperf3,rsync'. Without '-t', it can works on all applications by default.

Here are some example output.

1、curl
	$ curl https://check.mptcp.dev
	You are not using MPTCP.

	$ sudo python3 mptcpify.py -t curl &
	$ curl https://check.mptcp.dev
	You are using MPTCP.

2、iperf3
	'iperf.sh' can be obtained through th link below:
	https://github.com/Dwyane-Yan/bcc_test_iperf/blob/main/iperf.sh

	$ sudo ./iperf.sh
	[ ID] Interval Transfer Bitrate
	[ 5] 0.00-1.00 sec 11.4 MBytes 95.3 Mbits/sec

	$ sudo python3 mptcpify.py -t iperf3
	$ sudo ./iperf.sh
	[ ID] Interval Transfer Bitrate
	[ 5] 0.00-1.00 sec 87.0 MBytes 729 Mbits/sec
