Cool.

Bit of a misleading headline:

What exactly is misleading given there are several common algorithms used (cubic by Linux and compound by windows) and the gains are at least an aggregate 2x improvement on key performance metrics.

One thing I do see is that it hasn't yet been tested on real networks, only synthetic networks. It will be interesting to see if it provides real gains across the range of conditions, particularly in hyper optimized data centers.

Looks very interesting.

So we if we imagine this gains traction, could a mobile device use a different transport protocol for different network situations? Such as a phone going from 3G to 4G to wifi?

I guess the problem is the other end would have to adapt too?

Also if you are going to add new protocols, then would be not be better to add more message oriented protocols, rather than stream oriented? As many applications (twitter, payment instruction, email send) are message oriented.
