I haven't heard about that demo, but as I understand it, NLR gives you as many
lambdas as you like (or can pay for) at 10 Gbps apiece. So if they did 17.7
peak on what appears to have been a single lambda, I would think more is
feasible?

Subject: [FRIAM] Hi-speed transfer demo
Of interest. Yes, it was "lab" conditions, but on a pretty good-sized lab
bench. But hasn't someone recently mentioned a demo of 40Gbps through Lambda
Rail?
Researchers Set Record For Network Data Transfers
A team of university computer scientists, network engineers, and physicists
from the California Institute of Technology and the University of Michigan,
with partners at the University of Florida and Vanderbilt , set records for
data transfer speeds during a conference "bandwidth challenge" in Tampa, Fla.
The team achieved a peak throughput of 17.77 gigabits per second (Gbps)
between clusters of servers on the show floor of the SuperComputing 2006
conference in Tampa and the California Institute of Technology in Pasadena.
Following rules set for the challenge, the researchers used a single 10-Gbps
link provided by National Lambda Rail that carried data in both directions.
One of the key advances in the demo was Fast Data Transport (FDT), a Java
application developed by Iosif Legrand of Caltech, that runs on all major
platforms and achieves stable disk reads-and-writes and smooth data flow across
a long-range network. FDT streams a large set of files across an open TCP
socket, so that a typically large data set composed of thousands of files can
be sent or received at full speed without the network transfer restarting
between files... For more information, click here.
