Dear MPTCP enthusiasts, as one of the authors of https://datatracker.ietf.org/doc/draft-amend-tcpm-mptcp-robe/, I kindly request feedback from you, in particular however from the RFC6824/8684 authors and MPTCP implementers. With MPTCP RobE (Robust Establishment) we address the lack of MPTCP to reliably setup a MPTCP session, when the selected path for the initial session setup is malfunctioned. The MPTCP RFCs does not give any guidelines for this particular problem and it is left to the implementer to take care. For that we propose and compare different strategies in the draft document, separated by their demand on MPTCP protocol changes. Apart from that our claim is, that with these proposals compared to MPTCP, no additional security flaws are raised and any potential computational overhead is minimized. As we have presented at IETF 108 our progress (https://www.ietf.org/proceedings/108/slides/slides-108-tcpm-draft-amend-tcpm-mptcp-robe-00-00) in terms of the draft document, but moreover results from a mobile phone prototype over commercial Wi-Fi and cellular access, we aim for adoption at TCPM as soon as possible. In that sense it would be very valuable to get your feedback, so that we can incorporate this in our considerations. If you like to directly contribute to the draft document you will find the source at https://github.com/markusa/ietf-mptcp-robe. Br Markus
