MPTCP - Linux Kernel MultiPath TCP project

http://www.multipath-tcp.org/

MultiPath TCP (MPTCP) is an effort towards enabling the simultaneous use of several IP-addresses/interfaces by a modification of TCP that presents a regular TCP interface to applications, while in fact spreading data across several subflows. Benefits of this include better resource utilization, better throughput and smoother reaction to failures. Slides - explaining MultiPath TCP - are available in.pdf and.pptx format. You can also have a look at our Google Techtalk about MPTCP, or the MultiPath TCP tutorial given by Olivier Bonaventure at the IETF87.

The IP Networking Lab is implementing MPTCP in the Linux Kernel and hosting it on this website for users, testers and developers.

For questions, feedback,... please contact us at the mptcp-dev Mailing-List

If you use the implementation in scientific papers, please indicate in the paper the version of the implementation that you use and cite it as :

C. Paasch,S. Barre, et al., Multipath TCP in the Linux Kernel, available from http://www.multipath-tcp.org

Stable Release

MultiPath TCP v0.90 is available on ourrelease page.

Commercial support for Multipath TCP

Sébastien Barré and Gregory Detal, two of the keycontributors to the Multipath TCP implementation in the Linux kernel,are creating a company that will develop innovative products based onthis technology.

If you are working on a commercial application on top of Multipath TCPand need commercial-grade support, new features or backport toprevious kernel releases, just contactGregory Detal and Sébastien Barré directly to discuss with them about the services that they can offer.

The fastest TCP connection with Multipath TCP

Breaking the record of the fastest TCP connection - have a look here how we can achieve 51.8 Gbit/second with Multipath TCP.

Apple's iOS7 supports Multipath TCP for its traffic generated by Siri. Congratulations to Apple for pushing the first wide-spread deployment of MPTCP.

Citrix's Netscaler as well as theF5 BIG-IP also support Multipath TCP!

Linux Kernel MultiPath TCP in action

We did a little demo of MultiPath TCP used over Ethernet/WiFi/3G on our Linux Kernel implementation.

We start an ssh-session with X-redirection and launch xscreensaver demo on the distant MPTCP-capable server.

We then turn off Ethernet and WiFi and thanks to MultiPath TCP the ssh-session is able to handover the traffic to 3G without interrupting the user-experience.Without our MPTCP Linux Kernel the session would simply stop working and the user would need to restart the ssh-session.

In the video you see a trafficmonitor on the right, displaying the instantaneous amount of traffic going over each interface. Top is Ethernet, middle is WiFi and bottom is 3G.
