A GEANT Leap Forward In Networking For Research
An anonymous reader contributes: "A research backbone network interconnecting more than 30 countries, through which hundreds of universities can exchange traffic, with a backbone running at 10 Gbps, born on the 1st of December. Yes, it exists, and this research network is not even in the U.S.!
GEANT is a european initiative which has just come online, so if you're a student in Europe, you may have noticed a significant change in your downloads speeds since last week. You can even check its weathermap! Well, obviously backbone links are still unused ... but that shouldn't last long, once people notice the sheer amount of bandwidth."
"Yes, it exists, and this research network is not even in the U.S.!"
As if that's something hard to believe... considering the fast networks already developed and in development in Canada and Japan you'd think we could give other countries the credit they deserve. It's not like the US is the only country that knows how to string an Ethernet cable.
Plus, the Internet2 backbone is moving to OC192 in the near term. Saturate that...
"Wow, well done guys. Our new multi-gagabyte network is now fully operational"
"Cheers...."
"Uh... Boss, hold on...."
"What?"
"Someone just posted us to slashdot!"
*Poof* goes the bandwidth
Seriously though, if they get slashdotted their really isnt any hope for the rest of us.
Yes, it exists, and this research network is not even in the U.S!
Gosh! Outside the US! In Europe!
The Europeans really seem to be advancing don't they? A friend of mine visited Europe and told me that they've got TV, computers, mobile telephones, everything! How long before they catch up with the US?
However, they are still really lagging in cultural things. They don't have that many great places to hang out as in the US like Starbucks or MacDonalds (just little coffee shops and resturants which are all different!) and they don't have so many TV channels (and a lot of the ones they do have are in funny languages!). And they aren't as advanced politically as the US - they don't have the personal freedoms that we have, like the feedom to carry guns and, er, the other freedoms that we have.
(Yes, this is sarcasm).
There was interesting article about this a few weeks ago in the gaurdian newspaper.
Although it's pretty thin on technical details, it does provide some insight into some of the questions people are posting, such as why they need all this bandwidth, why the US arent part of the project etc.
I prob should have mentioned that OC192 is essentially 10Gbps in my earlier post. This means that Internet2 will be equiv (in terms of backbone speed) to GEANT in the near term. (You can read the PR about the Internet2 upgrade if you are interested.
There is a program called pathchar which seems to do a pretty good job of characterizing pipe size. I've used this to monitor my DSL bandwidth; PacBell has a 45Mbit line heading out of it's DSLAM's (at least in my area). It was designed to be used with symmetric connections, my DSL line (1.5/128) reports like 330K, but otherwise it's a good start at measuring paths.
From my office to microsoft's ftp servers I was easily able to determine that the slowest link is our T1 bewteen the ISP's T3 and our 10Mbps interface on our external router.
there are no stupid questions, but there are a lot of inquisitive idiots
With all the comments about using it for faster downloads, etc, etc, people seem to be missing the fact that it'll only really speed your downloads up if you're accessing another site on GEANT. Personally when I was a student, connecting to other academic sites was never particularly slow - but JANET (the UK academic net) doesn't have particularly good peering to transatlantic links (clearly due to the cost).
What GEANT will help make more possible is inter-site co-operation, and apps like high bandwidth video streams. In response to the guy who said it was a waste of money - give it time?
Seriously though, this has ( as the US based Education networks and the like do ) the capability to further increase benefits for all of the students and researchers at the connected institutions. One of the things that Internet2 doesn't have in quite as much abundance is overwhelming raw bandwidth availability. Can't find the time to visit another school to attend a lecture? A course you want to take isn't offered at your school, but is at another one?
Realtime video and remote tele-presence applications will easily consume this bandwidth and more ( assuming they aren't drowned out by DIVX and MP3s flying around. ).

Segmentation Fault ( core dumped )
This addresses fundamental routing issues, so my apologies to most of you, however I think some of this crowd needs some clarification (albeit a simplified version):
:)
To all those who are posting such things as "now all I need is fiber to my home" or "I wonder if the Slashdot effect can saturate it" or "how come my ping times to it are so slow?":
You should know that hosts on these networks are generally a mix of globally- and non-globally-accessable. Meaning, many POPs that are "hooked up" to some high-speed initiative like vBNS or Abilene also have "commodity links." Commodity links are normal T3s, etc that are hooked up to a commercial ISP. This makes the site multi-homed, and helps minimize the amount of non-research-related traffic being sent over the high-speed links, because if you want to look at www.cnn.com from, say, a vBNS-connected box, it'll go over the commodity link instead of vBNS.
So the answer is, yes: the Slashdot effect can probably affect GEANT's web site because the Slashdot effect would flood their commodity link. On the other hand, if you were at a GEANT node... good luck trying, and enjoy the pings

I think your logic is a bit flawed.
The pipes to the U.S. do not necessarily carry data originating from the U.S.
It shows that a large amount of traffic is routed through the U.S.
This may include data originating in the US, but also data from Europe. It may even include data originating from Europe and targeted for Europe.
