Re: 923 Mbps across the Ocean ...

Hello;

There was a 1.5 Gigabit per second uncompressed HDTV stream that was sent
U Washington to DC.

http://www.washington.edu/hdtv/next-gen.html

True, that was sent RTP over UDP, but if I was
going to send that data rate over a _dedicated_ link, I would use UDP. The
very high bit rate applications I have been involved with could all tolerate
some loss, and for the others, a little FEC could go a long way.

What kind of production environment needs a single TCP stream of data
at 1 gigabit/s over a 150ms latency link?

Just the fact that you need a ~20 megabyte TCP window size to achieve this
(feel free to correct me if I'm wrong here) seems kind of unusal to me.
