Internet2 Definition

A private Internet for the benefit of its member organizations, which include the U.S. National Science Foundation (NSF), the U.S. Department of Energy, more than 200 U.S. research universities, and over 60 private companies formed into a not-for-profit consortium. Internet2 is not a separate physical network, and it does connect to the present Internet, as required. Internet2 is a project of the University Corporation for Advanced Internet Development (UCAID), a not-for-profit entity created specifically to develop and manage the network.The Internet2 and its members are in the process of developing and testing technologies such as IPv6, multicasting, and quality of service (QoS) mechanisms in support of what they characterize as revolutionary Internet applications such as digital libraries, virtual laboratories, distance-independent learning, and tele-immersion. The Internet2 initiative is parallel and complementary to the Next Generation Internet (NGI) initiative funded by the United States federal government. The physical transmission infrastructure initially (1995) was in the form of the very-highspeed Backbone Network Service (vBNS), which was replaced by the Abilene Project. G.
