World's Fastest Internet Transfer Rate?
vrioux asks: "While browsing through available Internet service offerings in my area, I became puzzled by the large amount of different speed records that seem to have been achieved in the past months. Some say that 5.44Gbits was the fastest ever achieved, while others seem to think 923Mbits is still in the race. Is there anybody who really knows who holds the Internet transfer world speed record?"
are they measuring. I mean its one thing to have a really fast transfer rate from computer to computer if they are right next to each other, its another thing to go half way around the world.

On a side note, your standard fiber OC-192 is 10-Gbit/s. And your OC-48 is 2.45Gbit/s. While your OC-192s are definitly not common, its not unheard of for service providers with big ONS SONET networks to have them.
no one ever considers the task(time) of loading the data onto the computer when they quote this.
;)
when you use the internet, the data is already on your computer.
wow. I need to relax
Roughly 100 years ago, the world record for powered airplane speed was probably under 60 mph ... I imagine it's somewhat faster now.
(Of course, `Internet Speed Record' ... who really cares? I'll care when I can have this transfer rate to my house for $60/month :)

"It has a dual route, transatlantic capacity of 640 Gbits on 2 service fiber pairs backed up by 2 protection fiber pairs. This configuration provides a capability of transporting 4,096 STM-1's or approximately 9,700,000 circuits across the ocean."
It more depends what is being counted though. Your never going to get all of this fiber at once. If you count from a local isp the speed record or from the backbone or from a rual isp it all depends.
These mystery articles talking up "new internet speed records" are not talking about "mega-fast line capacity". Anyone can engineer a nice fat bundle of lines to up the ante - it just costs Money (specifically, LOTS OF).
What these people are going on about is the real-world actual measured data-throughput between a single pair of computers across "the internet" (usually across a significant chunk of the world).
Anyone who's tried to use any TCP based protocol (eg FTP, HTP) to send mind-warpingly large chunks of data understand the throughput limitations imposed on said communication as a direct result of large RTT latency.
I'm not sure about these two instances specifically (articles give essentially ZERO technical details) but many similar researches are an attempt to derive new (bigger, better, faster, and more eco-friendly) protocols which avoid the limitations of TCP.

This year's Supercomputing 2003 Bandwidth Challenge netted some cool results in this area including 23+gbps inside the US, 7.56gbps between the US and Japan, and 8.96gbps throughput to a remote network filesystem using GPFS. There are even some pretty graphs. My former co-workers at SDSC were involved in a lot of this work.
