Hi,
For those of you who don't remember, MP-TCP is an extension to TCP that
implements multipath, and can be used both for fast roaming (redundancy)
and for bandwidth aggregation. MP-TCP is able to cross NATs, and it can
reliably detect that TCP extensions are being corrupted by middleboxes and

Now if only thay had gotten the layering right... such a terrible wasted
opportunity.
(SCTP forever!)

In principle, the ISP should assign either a global address, or an address in
the range 100.64.0.0/10 (RFC 6598). This range was deliberately chosen to
not collide with RFC

There's quite a few good ideas in this draft, but the one that I find
intriguing is reporting RTT values in RPM (units of 1/60 Hz) rather than
milliseconds.
I wonder how well this works. I'll experiment with undergrads.
