New Nuts-n-bolts Talk paper accepted. Christoph Paasch, Mat Martineau, Peter Krystad and Matthieu Baerts have been working very hard on kernel Multipath TCP(RFC 6824) support. There have been difficulties in the past in upstreaming this implementation due to its invasive architecture; however, the authors feel that they have better understanding since the last time they showed up at netdev conf 0.1: The current MPTCP implementation has moved from it researchy origins and is already used by millions of devices in production environments. The protocol standardization is also now complete. For these reasons the authors feel that experience has gained them a lot of insight and they are ready to move forward with upstreaming. In this talk, the authors will do a gentle introduction of Multipath TCP and mention some uses cases already in production. They will discuss the challenges faced - both resolved and ongoing. More importantly they will be looking for feedback on how to best revamp the current implementation for upstreaming purposes.
