History
One of the aims of the Abilene project was to achieve 10 Gbit/s connectivity between every

In general, a node is a localized swelling (a "knot") or a point of intersection (a vertex).
Node may refer to:
In mathematics
* Vertex (graph theory), a vertex in a mathematical graph
*Vertex (geometry), a point where two or more curves, lines ...

Abilene and Internet2 and the Internet2 Network
The media often incorrectly used the term "Internet2 Network" when referring to the "Abilene Network". Some sources even suggest that Internet2 is a network wholly separate from the

. This is misleading, since, at the time of the Abilene Network, Internet2 was the consortium and not a computer network. It is possible that many news sources adopted the term Internet2 because it seems like a logical name for a next-generation
Internet backbone
The Internet backbone is the principal data routes between large, strategically interconnected computer networks and core routers of the Internet. These data routes are hosted by commercial, government, academic and other high-capacity network ...
. Articles that reference Internet2 as a network were in fact referring to the Abilene Network. Internet2 adopted the name ''Internet2 Network'' for its entire network infrastructure.
Abilene formed a high-speed backbone by deploying cutting edge technologies not yet generally available on the scale of a national network backbone. Abilene was a private network used for education and research, but was not entirely isolated, since its members usually provide alternative access to many of their resources through the public Internet.
