Until recently, Internet2 had a theoretical limit of 10 gigabits per second, but now, by sending data using 10 different colors of light over a single cable, operators are boosting the network's capacity to 100 Gbps. "It's now possible for a single computer to have a 10 gigabit connection and we needed to have a way of making sure that those kinds of demanding applications could be served at the same time as all the normal uses," said Internet2's chief executive, Doug Van Houweling. An institution typically has one 10 Gbps connection to the 100 Gbps Internet2 backbone for normal Internet usage, along with a second 10 Gbps connection it can tap on demand for specific needs, said Van Houweling.
The new Internet2 network was largely completed in late August, and its operators this week made it possible for researchers to temporarily grab an entire 10 Gbps chunk for specific applications, so that they don't slow down normal Internet operations. The Internet2 network, run by Level 3 Communications Incorporated, parallels the regular Internet to let universities, corporations and researchers share large amounts of information in real time.
Internet2 is already planning future expansion: by adding certain equipment the network can easily boost capacity another fourfold to 400 Gbps — something likely to begin in 12 to 18 months.
















to the gigga world
Aussie connections beat New Zealand's hands down. I'd be happy with your broadband to be honest.. mine is crap.
I pay $40 per month for 30GB on ADSL2+ where I usually get 16Mbps.
I'm quite happy with my connection
at 11 of each month i already passed that
it'd be nice if something like that actually carried internet data instead of just academic stuff that the internet used to carry in the 70's and stuff... i can imagine their 100gbps backbone sitting idle most of the time
janet is nothing like internet2, most uni connections are already more or less crippled at peak times
That's certainly true, our T1 line never gets above 120 KBps during the day
And my oh my, imagine the porn!

part of the reason for it's existence is to not replace the internet but be a separate internet mean for universities and research facilities and companiies who can afford to buy into it.
I assume you mean the Abilene network?
Serial Attached SCSI 2 (Not yet implemented) 6000 Mbit/s
Ultra-640 SCSI (16 bits/160 MHz DDR) (Not yet implemented) 5120 Mbit/s
SATA III (SATA-600) (Not yet implemented) 4800 Mbit/s
Fibre Channel 4GFC (4.25 GHz) 3400 Mbit/s
Serial Attached SCSI (SAS) 3000 Mbit/s
Thus, if you could make a
(pick one)
17-disk RAID 0 SAS2 array
20-disk RAID 0 Ultra-640 SCSI array
21-disk RAID 0 SATA III array
30-disk RAID 0 4GFC array
34-disk RAID 0 SAS array
(double that if you want RAID 10 or RAID 01)
then your Hard Drives could use all that 100 Gb/s bandwidth on the one computer.
But, let's say you're running 10 computers on a 10-port LAN that has an Internet2-100Gb/s connection on the WAN side.
Well then, that's a different story, isn't it?
In that case, if you have a
(pick one)
2-disk RAID 0 SAS2 array
2-disk RAID 0 Ultra-640 SCSI array
3-disk RAID 0 SATA III array
3-disk RAID 0 4GFC array
4-disk RAID 0 SAS array
(double that for RAID 10 or RAID 01).
on all ten machines, then you're golden. Each machine's HDD array can use 10 Gb/s. Since there's 10 of them and 10x10=100, your LAN is capable of sucking down 100Gb/s (on the whole). Put those 10 PCs into a distributed computing platform, and you just made one heck of a fast supercomputing cluster.
Still, if you've already got a supercomputer with 100's of gigabytes of RAM in it, the bus speed of your hard drives is hardly a limiting factor. I suppose that's why only those places that have supercomputers can justify hocking up to the Internet2 backbones, eh?
huh? did you mean to reply to http://www.neowin.net/news/main/07/10/13/g...t#comment585896 instead?
At least I got chicken!!
