Intenet2 Backbone Upgrades 231
An anonymous reader "Looks like Abilene, the backbone for Internet2 will join Canada's CA*Net3 and Europe's GEANT as one of the fastest research networks on the planet. According to this press release, Internet2 will be deploying 11 of Juniper network's freshly announced T640 platform. These puppies can cram 32 OC-192 (or 128 OC-48) interfaces into a single chassis. All in half a rack, too!" I'm
sure those students are very happy with their ping times. Meanwhile in the
real world... ;)

According to this page [dante.net] at Geante,
An important element of GÉANT is the development of connectivity with equivalent Research Networks in other world regions. Connectivity is being consolidated with the existing equivalents of GÉANT in North America (Abilene, CA*net) and in Asia-Pacific (SINET, KOREN, SingAREN) and developed further between Europe and the Asia-Pacific, North American, South American and Mediterranean regions
a bunch of extra regions get connected as well.

They have probably hunderds of mirrors around the world where the actual wares is downloaded from, you're automatically redirected to the closest one.
Works pretty fine here, they have one mirror in the same facility as where the Finnish University and Research Network [www.csc.fi] backbone is located, this gives me 4-5meg/s transfer speed from windowsupdate to my dorm at the campus of Helsinki University of Technology [www.hut.fi]

If you check out the traffic graphs, you can see that well over half the traffic is kazaa. (click on application-bits)

Taxpayers' dollars hard at work indeed! The cool thing is that at most times these nodes aren't anywhere near their maximum data transfers at any time that I check them. That's probably just because nobody really knows about it and only use it if they happen to connect to someone else on the network and their university has the routing setup correctly... Also, not all the universities in Canada I've connected to make full use of the network, some limit bandwidth to their users even on this "free" (gov't subsidized) network. From what I hear though, the free part will soon change and the universities/gov't offices will have to pay for it in the upcoming years, but right now it's basically free bandwidth for those on the network.
Microsoft's location on I2 (Score:2, Informative)
And for the poster who said Microsoft was not on I2, here is a press release [microsoft.com] stating that Microsoft was joining I2 in 1999.

There is probably transit through a few of the other ISPs also though.
There is much more than 10gbps bandwidth over the atlantic. In 2001 it was esimted there was 200gbps lit fibre.

First, these (and all core routers) have redundant power supplies. Second, the cords are screw-down DC power, which aren't going anywhere. Third, the front-panel throughput is a measure of how much traffic the line cards (ports on which all data enters and exits the router) can push, whereas the rear-panel throughput is a measure of how much the backplane can push between the (8) different line cards.

capacity vs speed (Score:1, Informative)
Remember that bandwidth is the measure of the width of the pipe (common sense, right?) so a fiber line can *carry* more data at once but not send the individual packets any faster to their destination.
speed= distance/time
bandwidth = data-amount/time
You will always have latency even with fat pipes, mainly due to speed of light constraints which other people have already mentioned.

Hmm...I2 is now...faster than light! Tear down the front page!
10 ms from VA to CA is about 3000 miles in 10 ms. That's information traveling round-trip (6000 miles!) in 10 ms, or 600000 miles/second.
Approximately 3.5 times the speed of light. Now that's impressive.
Let's not get carried away here. :)

The Internet Backbone is kind of an old idea. I mean the main centres are still there, but many modern ISPs are meshing their networks quite densely. The telco-based old guys are still sitting there refusing to peer with anyone, but those that are meshing up are making for a much more stable Internet, the way it was originally intended. Just try knocking the thing over when half the large ISPs are linked to each other at diverse points. If chunks of the Internet disappear, a few phone calls are made and peering agreements briefly become transit agreements. No more problem.
That being said, I'm in Australia, and our speeds are alot slower than most in our backbone networks. But I know for a fact that Verio US has 192 fairly well deployed. Down here we're nowhere near that. I know a few years ago, Optus was running STM16s (OC48) so they might be close now. Mind you I don't think they've sold so much bandwidth that they'd have gone that far yet.
