What is Internet2?
Internet2 started in 1996 as a group of corporations, universities and nonprofits interested in advanced research. The project acts as a laboratory for companies and researchers developing new technologies and also serves as a blueprint of what the Internet could look like in the future.
Most people associate video streaming over the Internet with chunky sound and halted pictures, for example, but the technology has made great strides within Internet2 to broadcast quality.
"You are hearing the real sound and seeing the real image. You're not looking at some grainy image on a computer screen," said Professor Brian Shepard, the coordinator of the music technology program at the University of Oklahoma School of Music.
Participants of Internet2 include Qwest Communications, Cisco Systems, Microsoft, Intel and Lucent Technologies, all of which have fallen on hard times with the economic downturn, making some wonder if Internet2 might not be at risk. But instead, the project is getting a power boost.
Internet2 announced this week that Qwest will extend its role as the keeper of the project for another five years and upgrade the backbone speed by four times to 10 gigabits per second by October 2003, roughly more than 155,000 times faster than a standard dial-up modem connection.
"Overall, if you look at how people are voting with their feet and their checkbooks, (Internet2) has been a success," said Ken Klingenstein, the director of the Internet2 project's middleware group.
Internet2 is powered by "Abilene," a telecommunications network run by Qwest, which links companies and universities around the country and their northern counterparts through Canarie, the Canadian version of Internet2. Abilene is put together with "off the shelf" equipment available in the telecommunications market, but it works more smoothly than the regular Internet, according to Internet2 spokesman Greg Wood, because relatively fewer people use the network and because it receives the constant attention of top researchers, which creates a fertile environment to test future applications.
"You wouldn't want to say it's frictionless, but we are skating on ice," Wood said.
Companies belong to Internet2 for different reasons, but Jill Arnold, the director of corporate relations at Internet2, says that the need to have a stake in innovation is a common motivator. "They're all here because they want to be part of a leading-edge activity," she said.
Through Internet2, tech companies have access to top research universities and researchers. They hope to translate these efforts into economic gain by helping develop better applications for the mass market.
"Originally, the thought was that this would be a small group of universities and a small group of companies working together," Arnold said.
In 1997, 10 universities, 11 corporations and six affiliate groups that are either educational or nonprofit institutions were involved. As of last summer, those numbers ballooned to 73 corporate, 185 university and 39 affiliates.
Wu's experience hints that the revolution may be televised after all, at least when it comes to education.
Ted Hanns, the director of application development at Internet2, says the network can allow speeds between 10mbps (megabits per second) and 15mbps for videoconferences, which is about 178 times faster than a dial-up modem, compared with regular broadband connections rates of 1.5mbps.
"Students are involved in their lesson, and they can see themselves involved in their lesson," said Christianne Orto, the director of recording and videoconferencing at the Manhattan School of Music.
Internet2 – the next generation of the Internet – is an ultra-high-speed network being developed by a nonprofit consortium of universities, industry and government to make the exchange of complex information simple.
Building on the current Internet, Internet2 involves the use of advanced technologies such as multicasting that will support new applications such as virtual laboratories and tele-immersion — a form of teleconferencing that makes users feel they are in the same room with a person who is miles away.
Internet2 is giving schools access to a new realm of clear, virtual digital experiences, allowing them to expand beyond their boundaries into the world of the future
Internet2 Project:
Building on the tremendous success of the last ten years in generalizing and adapting research Internet technology to academic needs, the university community has joined together with government and industry partners to accelerate the next stage of Internet development in academia. The Internet2 project, as it is known, is bringing focus, energy and resources to the development of a new family of advanced applications to meet emerging academic requirements in research, teaching and learning. Internet 2 addresses major challenges facing the next generation of university networks. The goals are,
Create a national network reserved for research & education use.
First and most importantly, creating and sustaining a leading edge network capability for the national research community. For a number of years beginning in 1987, the network services of NSFnet were unequaled anywhere else. But the privatization of that network and the frequent congestion of its commercial replacement have deprived many faculty of the network capability needed to support world class research. This unintended result has had a significant negative impact on the university research community.
Enable new types of network applications.
Second, directing network development efforts to enable a new generation of applications to fully exploit the capabilities of broadband networks media integration, interactivity, real time collaboration to name a few. This work is essential if new priorities within higher education for support of national research objectives, distance education, lifelong learning, and related efforts to be fulfilled.
Transfer the new technology to the public.
Third, integrating the work of Internet2 with ongoing efforts to improve internet services for all members of the academic community. A major goal of the project is to rapidly transfer new network services and applications to all levels of educational use and to the broader Internet community, both nationally and internationally.
