AARNet or Australian Academic and Research Network provides Internet services to the Australian education and research communities and their research partners. AARNet built the Internet in Australia. In 1995, the Australian Vice-Chancellors' Committee (AVCC) transferred AARNet1 as a going concern to Telstra who then operated it as the initial Telstra Internet. Today, AARNet is Australia's National Research and Education Network (NREN). It forms the Australian component of the global advanced Research and Education Internet network. AARNet Pty Ltd, which owns and operates the AARNet, is a not-for-profit company limited by shares. The shareholders are 38 Australian universities and the Australian CSIRO. AARNet's services in addition to Internet connectivity include Eduroam, voice, video and data storage services and a content mirror.〔http://mirror.aarnet.edu.au/〕 ==History== AARNet was initially built between the University of Melbourne in Melbourne, where the international Internet feed initially landed, and university and CSIRO facilities in all Australian state capital cites and the Australian National University in Canberra. AARNet was formed in 1989 by the Australian Vice-Chancellors' Committee (AVCC). In 1989, Robert Elz established the first permanent Internet feed to Australia, at the University of Melbourne. Until this time, researchers within Australia had limited access to the ARPAnet, due to the high expense of providing communications between Australia and the United States. The national network infrastructure generally consisted of groups of hosts connected throughout the country exchanging mail and files on a periodic schedule using the SUN3 software and protocols, with several international dial-up links around the country exchanging this information where required. AARNet was initially built as a multi-protocol network, comprising Internet Protocol (IP) as well as DECnet and X.25 so as to accommodate pre-existing ACSnet and SPEARnet systems then in current use. With the rapid subsequent growth in popularity of the Internet, AARNet soon evolved into an IP-only network. In 1988, there were a number of popular network protocols, such as IBM SNA and X.25, and the ARPANet's IP protocol was only beginning to become favoured. Australian National University staff members Geoff Huston and Peter Elford were seconded by the AVCC in 1989 and tasked with technical management and build of the new network. AARNet introduced its 'value added reseller' program to allow Internet service providers (ISPs) to use its network, the first being Connect.com.au in May 1994.〔 AARNet gradually became a wholesale backbone ISP, serving over 300 smaller ISPs by June 1995. At that point, about 20% of total AARNet traffic was from these other users, and AVCC decided to sell the AARNet commercial assets to Telstra, who currently operates it under the name Telstra Internet. In early 1997, AARNet2 went into service, a network that used ATM links and Internet services under a contract with Cable & Wireless Optus (CWO), now Optus. AARNet became a separate company from the AVCC in 1999. In 2001 AARNet deployed its own international capacity by acquiring 310 Mbit/s of capacity from Sydney via Hawaii to Seattle. As of 2006, the current network is known as AARNet3, and the backbone uses a dark fibre network provided by Nextgen Networks. 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「AARNet」の詳細全文を読む スポンサード リンク
