Internet2 is a not-for-profit United States computer networking consortium led by members from the research and education communities, industry, and government.〔("About Internet2" ), Retrieved on 2009-06-26〕 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,〔("Internet2 University Members List" ), Retrieved on 2013-11-14〕 9 partners and 76 members from industry,〔("Internet2 Corporate Members" ), Retrieved on 2013-11-14〕 over 100 research and education networks or connector organizations,〔("Internet2 members: Research & Education Networks" ), Retrieved on 2013-11-14〕〔("Internet2 members: Communities & Groups" ), Retrieved on 2013-11-14〕 and 67 affiliate members.〔("Internet2 Affiliate Members List" ), Retrieved on 2013-11-14〕 Internet2 operates the Internet2 Network,〔("Internet2 Network" ), Retrieved on 2009-06-26〕 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.〔("Internet2 K20 Connectivity Data" ), Retrieved on 2009-06-26〕 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,〔("Internet2 Performance Initiative" ), Retrieved on 2009-06-26〕 secure identity and access management tools〔("Internet2 Security Directory and Related Links" ), Retrieved on 2009-06-26〕 and capabilities such as scheduling high-bandwidth, high-performance circuits.〔("Internet2 Dynamic Circuit Network" ), Retrieved on 2009-06-26〕 Internet2 members serve on several advisory councils,〔("Internet2 Advisory Councils" ), Retrieved on 2009-06-26〕 collaborate in a variety of working groups and special interest groups,〔("Internet2 Working Groups, SIGs, and Advisory Groups" ), Retrieved on 2009-06-26〕 gather at spring and fall member meetings,〔("Internet2 Member Meetings" ), Retrieved on 2009-06-26〕 and are encouraged to participate in the strategic planning process.〔("Internet2 Strategic Planning" ), Retrieved on 2009-06-26〕 ==History== 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.〔("Internet2 - Terms of Use" ), Internet2.〕 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.〔("Optical networking: The next generation - CNET News.com, By Marguerite Reardon (Staff Writer), Published October 11, 2004 4:00 AM PDT )〕 During 2004–2006, Internet2 and NLR held extensive discussions regarding a possible merger.〔("Internet2, National Lambda Rail, In Merger Talks (July 18, 2005)" )〕 Those talks paused in spring, 2006, resumed in March, 2007, but eventually ceased in the fall of 2007,〔(Internate archive of now defunct www.internet2-nlr.org site) )〕 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.〔("Speedy Internet2 gets 10x boost - USAToday.com, By Anick Jesdanun (AP Internet Writer), Published October 11, 2007 8:16 AM" ), Retrieved on 2009-06-26〕 In October, 2007, Internet2 officially retired Abilene and now refers to its new, higher capacity network as the Internet2 Network. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Internet2」の詳細全文を読む スポンサード リンク
