May 2017 – Multipath news May 09 2017 Information 0 comments Welcome to this second issue of Multipath News. Feel free to send suggestions or any feedback to multipath-news@tessares.net or through our online form. IETF MPTCP mailing list The IETF mailing list has been pretty active during April 2017. The first important message was posted by Christoph Paasch. In this message, he summarises how he has implemented the new handshake proposed for RFC6824bis. This is an important milestone since this confirms that the new design proposed by Christoph works as expected. Sayee Kompalli Chakravartula started several discussion threads on how to reduce some of the perceived overhead with Multipath TCP. Multipath TCP covers each data with a DSS option, even if there is only one subflow. Sayer argues that the DSS option consumes some space in the header and explores techniques to avoid sending DSS options when there is a single subflow. However, the presence of various types of middleboxes makes this problem more difficult than it could appear at first glance has explained by Olivier Bonaventure. Then, most of the bandwidth on the MPTCP mailing list has been consumed by various discussions on a consensus call that was initiated by the chairs . Various arguments have been raised by people in favour or against pursuing such work within the MPTCP mailing list. The mptcp-dev mailing list The mptcp-dev mailing list has been much quieter with only 24 emails exchanged during April 2017 . François Finfe has reported problems with the retransmission of some RST segments that include the MP_FASTCLOSE option. He fixed this bug later. Scientific publications The US Department of Energy recently issued its Network2025 report from its Feb 2016 workshop. This report provides a roadmap of key networking issues for the short (1-3 yrs), medium (4-6 yrs), and long term (10-12 yrs). It notes that multipath transport protocols, such as MPTCP, could play an important role to support very high speed transmissions over heterogeneous paths. Michele Polese et al. use simulations to analyse in « TCP in 5G mmWave Networks: Link Level Retransmissions and MP-TCP » the interactions between Multipath TCP and the techniques that are considered in the physical and MAC layers for the mmWave communications that will be included in future 5G networks. Feng Zhou et al. use measurements over the Nornet network to analyse in « The Performance Impact of Buffer Sizes for Multi-Path TCP in Internet Setups » how buffer sizes affect the performance of Multipath TCP. Their main conclusions are that MPTCP provides robust performance and can achieve performance advantages over TCP. Furthermore, buffer requirements remain reasonably small and the performance is independent of the path chosen for the initial subflow. Mathieu Coudron and Stefano Secci propose in « An implementation of multipath TCP in ns3 » a new simulation model for the ns-3 simulator. Older ns-3 models such as [Chinani+2011] or [Kheirkhah2015] have been used for some papers. This new ns-3 model is compared with the Multipath TCP implementation in the Linux kernel. Hopefully, this model will be officially included in a future release of ns-3. Ho-Dac-Duy Nguyen et al. discuss in « Can MPTCP Secure Internet Communications from Man-in-the-Middle Attacks? » whether by creating disjoint inter domain paths that would be used with Multipath TCP it would be possible to counter some man-in-the-middle attacks.
