HISTORY OF INTERNET 2

As the Internet gained in public recognition and popularity, universities were among the first institutions to outgrow the Internet's bandwidth limitations because of the data transfer requirements that many academic researchers need to collaborate with their colleagues. Some universities wanted to support high-performance applications like data mining, medical imaging and particle physics. This resulted in the creation of the very-high-performance Backbone Network Service, or vBNS, developed in 1995 by the National Science Foundation (NSF) and MCI, specifically to meet the needs of the supercomputers at educational institutions. The concept of the “next-generation Internet” was born. After the expiration of the NSF agreement, vBNS largely transitioned to providing service to the government. As a result, the research and education community founded Internet2 to serve its unique networking needs.

The Internet2 Project was originally established by 34 university researchers in 1996 under the auspices of EDUCOM (later EDUCAUSE), and was formally organized as the not-for-profit University Corporation for Advanced Internet Development (UCAID) in 1997. It later changed its name to Internet2. Internet2 is a registered trademark. The Internet2 consortium administrative headquarters is located in Ann Arbor, Michigan, with offices in Washington, D.C.
The Internet2 community, in partnership with Qwest, built the first Internet2 Network, called Abilene, in 1998 and was a prime investor in the National LambdaRail (NLR) project. During 2004–2006, Internet2 and NLR held extensive discussions regarding a possible merger. Those talks paused in spring, 2006, resumed in March, 2007, but eventually ceased in the fall of 2007, due to unresolved differences.

In 2006, Internet2 announced a partnership with Level 3 Communications to launch a brand new nationwide network, boosting its capacity from 10 Gbit/s to 100 Gbit/s. In October, 2007, Internet2 officially retired Abilene and now refers to its new, higher capacity network as the Internet2 Network

Objectives

Internet2 provides the U.S. research and education community with a network that satisfies their bandwidth-intensive requirements. The network itself is a dynamic, robust and cost-effective hybrid optical and packet network. It furnishes a 100 Gbit/s network backbone to more than 210 U.S. educational institutions, 70 corporations and 45 non-profit and government agencies.
The objectives of the Internet2 consortium are:
Developing and maintaining a leading-edge network.
Fully exploiting the capabilities of broadband connections through the use of new-generation applications.

Transferring new network services and applications to all levels of educational use, and eventually the broader Internet community.
The uses of the network span from collaborative applications, distributed research experiments, grid-based data analysis to social networking. Some of these applications are in varying levels of commercialization, such as IPv6, open-source middleware for secure network access, Layer 2 VPNs and dynamic circuit networks.

Achievements

These technologies and their organizational counterparts were not only created to make a faster alternative to the Internet. Many fields have been able to use the Abilene network to foster creativity, research, and development in a way that was not previously possible. Users of poor quality libraries can now download not only text but sound recordings, animations, videos, and other resources, which would be otherwise unavailable. Another application is the robust video conferencing now available to Internet2 participants. Neurosurgeons can now video conference with other experts in the field during an operation in a high resolution format with no apparent time lag.
