Yeah. They were doing experiments with LTE, which has pretty horrendous latency. (As in driving around Cambridge with an LTE modem and collecting packet traces.) (Dave -- they were doing *experiments*. Networking academics doing actual experiments, imagine that.) > I would have been much happier had the work continued (has it?) Keith got a position (no suprise there, he's very good), so he's very busy with teaching and setting up his research team. But I see he's published a related paper at SIGCOMM last year: Anirudh Sivaraman, Keith Winstein, Pratiksha Thaker, Hari Balakrishnan. An experimental study of the learnability of congestion control.
