Often the faster/newer/sexier gear had been tested on these 'test' networks prior to deployments in the field. Steve is right though, it's not all ipv4 on the links...

Wearing my researcher hat, the answer depends on what sort of research you're trying to conduct. There are more things to do with a fiber than just running IPv4 over it. --Steve Bellovin, http://www.research.att.com/~smb
Public Interest Networks (was: Re: Consortium sheds light on dark fiber's potential)
Vicky, I apologize if I am hijacking your thread. Is it just me or does all this talk of Research (and other Public Interest) Networks and logical separation by layer 1/2 leave [everyone] nonplussed? How is logical separation of a network [say via MPLS] much different than using a lambda to do the same thing? It seems kind of dumb to me that a network that is spending the money to buy capacity is selling a 2.5G or 10G wave to universities as any kind of improvement... I'm not even sure they could do it at a better price than a desperate telco that is selling the underlying fiber in the first place. Engineering idea: All the constituent folks do the same network, but build it as a single logical network, with say all 40x10G Lambdas on it. Everyone is given a 2.5G or 10G MPLS tunnel with the ability to use all unused bandwidth that is available on the network at that time... That would at least have some legs and create some value for having more membership. This smacks me as similar to Philadelphia wanting to deploy universal WiFi and charging $20-$25/month for it -- a free network to the city makes sense, afterall they pay taxes -- a psuedo-commercial service, what's the point? Do these government (and other so-called Public Interest) networks really make sense in the U.S. or is everyone still stuck in a timewarp when/where the NSFnet made sense because no one (commercially) could/would step up to perform the same function. Hopefully there is some operational content in there... If you don't see an on-list response from me, you probably know why.
