Could this be applied within a NATed network without cooperation of the server outside the NAT? That way you could at least move your laptop back and forth between wired and wireless connections inside the office or home without breaking all your sessions.
- songgao 12y agoYes! The design of MPTCP specifically takes that into considerations since most of hosts are behind a NAT. It basically initiates may normal TCP connections as subflows. All the middle-boxes would see normal TCP connections while the two MPTCP-aware endpoints split/aggregate traffic using multiple subflows.

- Scramblejams 12y agoSo you need an MPTCP-aware endpoint at the other end of the connection? I was imagining something that could be implemented unilaterally by a savvy home/office user just to ease the disruptions of switching between wired and wifi connections inside a NAT.
- songgao 12y agohmm.. well I think you can always use some sort of proxy, like VPN or an application proxy. edit: typo
