where's the support for Internet2.
Who needs Internet2?
In case that one disappeared in the general Juha troll filter, I'd like to hear a good answer to that question, too. The basis of Internet2 seems to be that it is possible to build a higher- performing and generally more advanced infrastructure when there are no ROI or market considerations to worry about.
Having looked inside the networks of some large commercial operators, I am interested in what further fraction of the bleeding edge the Internet2 folk think they can bring to the table.
If your question Joe is 'what is the justification for internet2?', then I'd say there seems to be at least two commonly cited ones. One is the use in current large applications such as 'grid' computing, a la DTF. Connecting super computer centres may consume a lot of bandwidth. Climate models, particle physics results etc. The other one is that the internet2 is supposed to spurr new application development, showing what *can* be done with huge amounts of bandwidth when it's available at low cost. One of the more PR friendly applications would probably be the 'virtual teleconferencing' systems, where 3d models are transmitted along with the video, allowing participants to be rendered in 3d at each end. (Enables you to make direct eye contact, surprisingly important.) So in short, the internet2 initiatives aren't so much about networking anymore, as applications. On the other hand, the vBNS has native multi-cast, Abilene supports IPv6, and CA-net3 is intended to be 'all optical'; they're developing OBGP for instance. If your question was something else, then I'll get blasted for being OT.
