   Ever wondered if there was some tech which could help you move your laptop move from ethernet connection to wireless without applications noticing?
   MPTCP was designed for that, I was having a look how it works, and how usable it is for such purposes.

     @globalc There's also QUIC, entirely application level, no system configuration required.

     ...but great article nevertheless. I didn't know existing apps could be retrofitted to use MPTCP via mptcpize. @globalc

     @globalc Very good article. Middle boxes, particularly NAT gateways, are one of the reasons why we can't simply improve TCP. Even when they don't actively block MPTCP, they forget idle connections after a few minutes, requiring constant traffic to keep them open. This wastes power and data on mobile devices.

     @codewiz Regarding QUIC for this, I agree it can help to switch to other underlying media/change IP without the application level noticing. Still the applications need to learn QUIC for that, and I also think combining throughput of multiple underlying media is not done, MPTCP can do that.
     This is an awesome description of the QUIC concepts: https://www.smashingmagazine.com/2021/08/http3-core-concepts-part1/
