Internet2 is a not-for-profit United States computer networking consortium led by members from the research and education communities, industry, and government.The Internet2 consortium administrative headquarters are located in Ann Arbor, Michigan, with offices in Washington, D.C. and Emeryville, California.
As of November 2013, Internet2 has over 500 members including 251 institutions of higher education,9 partners and 76 members from industry, over 100 research and education networks or connector organizations, and 67 affiliate members.
Internet2 operates the Internet2 Network,an Internet Protocol network using optical fiber that delivers network services for research and education, and provides a secure network testing and research environment. In late 2007, Internet2 began operating its newest dynamic circuit network, the Internet2 DCN, an advanced technology that allows user-based allocation of data circuits over the fiber-optic network.
The Internet2 Network, through its regional network and connector members, connects over 60,000 U.S. educational, research, government and "community anchor" institutions, from primary and secondary schools to community colleges and universities, public libraries and museums to health care organizations.
The Internet2 community develops and deploys network technologies for the future of the Internet. These technologies include large-scale network performance measurement and management tools,secure identity and access management tools and capabilities such as scheduling high-bandwidth, high-performance circuits.
Internet2 members serve on several advisory councils,collaborate in a variety of working groups and special interest groups, gather at spring and fall member meetings, and are encouraged to participate in the strategic planning process.
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 faced by academic researchers who needed 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 for supercomputers at educational institutions. 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 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 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.
In 2010, Internet2 received a $62.5 million American Recovery and Reinvestment ACT grant,which allowed Internet2 to put in place a long term IRU for fiber and upgrade the network with its own DWDM optical network system. Ciena later announced that this was the first 100G nationwide optical network. The upgrade to the new optical system was completed in December 2012.
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:
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.
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.[ citation needed ]
The Internet2 Driving Exemplary Applications (IDEA) award (not to be confused with IDEA awards) was first announced by Internet2 in 2006 as a way of recognizing those who create and use advanced network applications at their best.The judging is conducted by many universities and based upon the following criteria:
Winners of the award are announced each year at the Spring member meeting: 2006,2007, 2008.

It serves 18 million users and is the busiest National Research and Education Network in Europe by volume of data carried. JANET was previously a private, UK government-funded organisation, which provided the Janet computer network and related collaborative services to UK research and education.
A wide area network (WAN) is a telecommunications network that extends over a large geographical area for the primary purpose of computer networking. Wide area networks are often established with leased telecommunication circuits.
Packet switching is a method of grouping data that is transmitted over a digital network into packets. Packets are made of a header and a payload. Data in the header is used by networking hardware to direct the packet to its destination where the payload is extracted and used by application software. Packet switching is the primary basis for data communications in computer networks worldwide.
Abilene Network was a high-performance backbone network created by the Internet2 community in the late 1990s. In 2007 the Abilene Network was retired and the upgraded network became known as the "Internet2 Network".
AARNet provides Internet services to the Australian education and research communities and their research partners.
National LambdaRail (NLR) was a 12,000-mile (19,000 km), high-speed national computer network owned and operated by the U.S. research and education community. In November 2011 the control of NLR was purchased from its university membership by a billionaire Patrick Soon-Shiong. NLR ceased operations in March 2014.
The Corporation for Education Network Initiatives in California is a nonprofit corporation formed in 1997 to provide high-performance, high-bandwidth networking services to California universities and research institutions. Through this corporation, representatives from all of California's K-20 public education combine their networking resources toward the operation, deployment, and maintenance of the California Research and Education Network, or CalREN. Today, CalREN operates over 8,000 miles of fiber optic cable and serves more than 20 million users.
Fiber to the x or fiber in the loop is a generic term for any broadband network architecture using optical fiber to provide all or part of the local loop used for last mile telecommunications. As fiber optic cables are able to carry much more data than copper cables, especially over long distances, copper telephone networks built in the 20th century are being replaced by fiber.
Optical networking is a means of communication that uses signals encoded in light to transmit information in various types of telecommunications networks. These include limited range local-area networks (LAN) or wide-area networks (WAN), which cross metropolitan and regional areas as well as long-distance national, international and transoceanic networks. It is a form of optical communication that relies on optical amplifiers, lasers or LEDs and wave division multiplexing (WDM) to transmit large quantities of data, generally across fiber-optic cables. Because it is capable of achieving extremely high bandwidth, it is an enabling technology for the Internet and telecommunication networks that transmit the vast majority of all human and machine-to-machine information.
A computer network is a group of computers that use a set of common communication protocols over digital interconnections for the purpose of sharing resources located on or provided by the network nodes. The interconnections between nodes are formed from a broad spectrum of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies.
UDP-based Data Transfer Protocol (UDT), is a high-performance data transfer protocol designed for transferring large volumetric datasets over high-speed wide area networks. Such settings are typically disadvantageous for the more common TCP protocol.

UEN services benefit more than 60,000 faculty and staff, and more than 780,000 students from pre-schoolers in Head Start programs through grandparents in graduate school. UEN headquarters are in Salt Lake City at the Eccles Broadcast Center on the University of Utah campus.
40 Gigabit Ethernet (40GbE) and 100 Gigabit Ethernet (100GbE) are groups of computer networking technologies for transmitting Ethernet frames at rates of 40 and 100 gigabits per second (Gbit/s), respectively. These technologies offer significantly higher speeds than 10 Gigabit Ethernet. The technology was first defined by the IEEE 802.3ba-2010 standard and later by the 802.3bg-2011, 802.3bj-2014, and 802.3bm-2015 standards.
eCorridors is an information technology program to promote and facilitate broadband access for communities of Virginia and nearby areas. It was developed by faculty at the Virginia Polytechnic Institute and State University (VT) in the spring of 2000.
The Internet in South Africa, one of the most technologically resourced countries on the African continent, is expanding. The Internet country code top-level domain (ccTLD) .za is managed and regulated by the .za Domain Name Authority (.ZADNA) and was granted to South Africa by the Internet Corporation for Assigned Names and Numbers (ICANN) in 1990. Over 60% of Internet traffic generated on the African continent originates from South Africa. As of July 2016, 29.3 million people were Internet users.

A dynamic circuit network (DCN) is an advanced computer networking technology that combines traditional packet-switched communication based on the Internet Protocol, as used in the Internet, with circuit-switched technologies that are characteristic of traditional telephone network systems. This combination allows user-initiated ad hoc dedicated allocation of network bandwidth for high-demand, real-time applications and network services, delivered over an optical fiber infrastructure.
10G-PON is a 2010 computer networking standard for data links, capable of delivering shared Internet access rates up to 10 Gbit/s over existing dark fiber. This is the ITU-T's next generation standard following on from G-PON or Gigabit-capable PON. Optical fibre is shared by many subscribers in a network known as FTTx in a way that centralises most of the telecommunications equipment, often displacing copper phone lines that connect premises to the phone exchange. Passive optical network (PON) architecture has become a cost-effective way to meet performance demands in access networks, and sometimes also in large optical local networks for "Fibre-to-the-desk".
