Internet2 Turns 10 and Upgrades
An anonymous reader writes "As an update to a previous story, Internet2 is celebrating its 10th anniversary in Chicago this week at it's fall conference. In addition, they're announcing the initial stages of their second significant network upgrade of their backbone network. Engineers are providing daily blog updates on the network install process as the old network is transitioned to the new. In addition to changing to a Level3-managed and Internet2-provisioned DWDM transport system for backbone capacity, I2 is implementing a new connection-oriented backbone network based on the Ciena CoreDirector platform in concert with the routed IP network."
I'm waiting for Internet3 before upgrading. ;)

Not much. I'm at an I2 site and when I do big downloads from other I2 sites, they're noticably faster than from places like Redhat, Novell, etc. Sure, there's some technology in I2 that allows for more reliably low latency connections but you'd be hard pressed to find a web based application that would need that tech that I1 doesn't already serve (provided you're willing to spend the money for your last mile connection of course).
It lets college students quickly transfer MP3 files to other Abilene network members.
I presume there might be other uses too. Like videos, I guess.
It's a bigger series of tubes.
I2 from a connectivity standpoint really isn't anything different from I1. It's still an IP routed network and all your normal IP routed toys (www, ftp, home brew app) still work as advertised. The term Abilene is actually the name of the I2 backbone network. It was spawned as a second generation IP network (and yes it can route IPV6 natively) to connect research institutions. Allowing them to utilize the network for research and high speed data transfers. What kind of research? Well anything really, hear about those doctors doing remote robotic surgery? That data probably was traversing the Abilene backbone. Grid computing in acedemia? Probably connected via Abilene .
:).
Just like the I1 backbone, Abilene, being a backbone network, peers and eventually splits off to regional controlled networks. The one I am familiar with is OARNet (Ohio Acedemic Research Network). OARNet provides high speed connectivity to Ohio campuses and peers with the Abilene I2 backbone in Indianapolis (from OARNet's POP in Cleveland).
From an I2 connected campus (meaning you have access to the Abilene backbone at somepoint), there really isn't anything special to connect over the Abilene core. The network gurus had the IPV4 routing setup in such a way that if you connected to an IP address that was available via Abilene, the data would go that path. Otherwise, it would route out over the standard I1 connection. Most of the time when I would have to download some big ISO images, I would specifically look for an Abilene (I2) connected peer. Downloads over 10MBit weren't uncommon (mostly limited by the load on at the server on the other end). Pretty cool really. I'm sure others around are using it for more important stuff other than downloading ISOs
Wow...that is a lot of words that totally don't say anything.
Sig removed because it was obnoxious
