Internet2 speeds things up ■The newer, faster Internet connects 180 universities and offers many advantages By Andrew Adams Oregon Daily Emerald Most students don’t realize that when they sign on to the Internet through the campus server they are actually signing on to Internet2, a system completely different than what the majority of net users surf. Internet2 is a recently developed high-speed research network that connects 180 universities at levels quicker and more efficient than the standard Internet system. The system originated in 1995 with a grant from the National Sci ence Foundation. Corporations and universities then came togeth er to maintain and improve the system. The University has been using Internet2 for the past two years and researchers in the Com puting Center are continually ex perimenting and adjusting the University’s part in the system. Lucy Lynch, an academic and user support specialist with the Computing Center, said most stu dents are completely unaware they’re using a different Internet system when they log on from the campus. “To most people this is transpar ent,” she said. “It’s seamless.” She said the system originated to give universities a more direct and quicker route to transfer large amounts of research information. “Traffic travels on a different path, a more direct path,” she said. Internet2 also has a larger band width than the regular Internet, which Lynch explained allows users to transfer and view “broad cast quality” audio and video. One other key difference be tween the two Internets, Lynch said, is that programmers on Inter net2 have more freedom to experi ment with new technology. She explained that on the standard In ternet programmers fear using un proven systems because a system crash could result in lost revenue. Lynch said an example of Inter net2 being more advanced than the regular Internet is that it uses the sixth version of Net protocol and the standard Internet still uses the fourth version. i Operational network High-speed education The University is part of the Abilene network, which the Internet system. ® Abilene router node SOURCE: http://www.internet2.edu Assistant director of academic user services at the Computing Center )oe St. Sauver analyzes the University’s use of Internet2 and also helped Eastern, Western and Southern Oregon universities set up Internet2 connections. Most of the schools in the Ore gon University System are linked together on Internet2 via a server operated on the University cam pus. St. Sauver explained a big ad vantage of the system is that while it may be smaller, it has a larger rate of connectivity. Traffic travels on a different path, a more direct path. Lucy Lynch support specialist UO Computing Center if “The number of connected sites is smaller, but the sites are larger,” he said. “A typical small liberal arts college might connect to the commodity Internet with the smallest size connection available; from Internet2 now is a [connec tion] one hundred times that size.” St. Sauver said Internet2 will eventually link K-12 schools and is even planned to link a growing list of international locations in South America and Latin America. He also said a key element of In ternet2 is research and experimen tation. One of the current projects is multicast systems that are being developed in the University’s Video Lab. Hans Kuhn, an academic and user support specialist developing multicast technologies, said only 5 to 10 percent of the regular Inter net is capable of supporting multi cast, but 50 percent of Internet2 can support the new technology. He explained multicast systems speed up the transfer of large amounts of information by delay ing the copying of such informa tion until the last possible second. Kuhn said with the standard Inter net, a server has to copy the infor mation for every receiver. This process creates long delays as all the recipients wait for the server to copy information for them. Multi cast cuts that copying process out of the information loop. “Rather than send 100 copies over the Internet you only send one,” he said. “It’s like if I would send one copy to the office secre tary and she’d Xerox copies and put it in everyone’s box.” Kuhn said multicast is ideal for sending and receiving live audio and video broadcasts through the Internet. He will put this to a test when he transmits a webcast of a meet ing of university programmers at the University of Hawaii in Janu ary. “It’ll be a real-world application of what we’re doing,” he said.
