Help us measure MPTCP over the public Internet
We have started to analyse the MPTCP packets received on http://www.multipath-tcp.org and would like to have more data on the behavior of MPTCP over the public Internet. We’ve seen some unexpected results by looking at these packets. For example, some MPTCP connections announce up to 14 different addresses. We would like to better understand all the factors that influence the performance of MPTCP over the public Internet.
To collect more MPTCP packets, we have installed a new measurement server. The server is currently connected at 100 Mbps and we have enabled the echo and discard services. We would appreciate if all MPTCP users could help us to improve our understanding of the operation of MPTCP in the global Internet by generating MPTCP traffic towards this server. The results of this analysis will, of course, be released as technical report.
If you use MPTCP on Linux or (even better) on any other OS, preferably on a physical host that has two or more interfaces (or at least an IPv4 and IPv6 address), could you perform the following tests :
dd if=/dev/zero bs=1M count=10 | nc discard.multipath-tcp.org 9
This command will send 10 Mbytes of zeros to our server.
dd if=/dev/zero bs=1M count=10 | nc echo.multipath-tcp.org 7 >> /dev/null
This command will send 10 Mbytes of zeros to our server and it will return them by to you
Feel free to increase the number of blocks for larger transfers. If you use MPTCP on a mobile device, we’d be very interested in measurements from different locations. If you have access to another MPTCP implementation, we’d love to receive measurements packets from non-Linux hosts.
