Internet2

from Wikipedia, the free encyclopedia

The Internet2 is a project for a faster Internet , based on a fiber optic backbone that offers very high bandwidths . It was initiated in 1996 by the University Corporation for Advanced Internet Development (UCAID).

The network itself was codenamed Abilene (based on the city of Abilene in Kansas , which became known as the terminus of the railroad in the 19th century ).

The original goal was transmission rates of up to 2.48 Gbit / s and higher. 10 Gbit / s has been available since 2004. It is noteworthy that the Internet2, unlike the Internet, did not emerge from the military sector.

Since April 24, 1998, the Internet2 has linked 115 American universities and research institutions. In 2011 there were more than 300 institutions. According to its own information, Internet2 will have almost 500 US members and 70 international partner networks in 2020.

In 1999, German, French, Italian and British partner organizations also signed a Memorandum of Understanding with UCAID in order to gain access to the Internet2. On June 30, 2000, the German Internet2 was introduced. The so-called G-WiN largely consisted of 10 GBit lines and connected over 500 German universities and research institutions. It was operated by the German Research Network (DFN). In 2006, its successor, the faster X-WiN , was put into operation, which is also operated by the DFN-Verein. In the X-WiN, speeds of over 1,000 Gbit / s (1 Terabit / s) can be achieved.

Internet2 is a physical communication structure and does not designate an explicit Internet Protocol ; both IPv4 and IPv6 can be used on it.

In 2004, Professor Steven Low's team achieved a new throughput record of over 101.1 Gbit / s on the route between Los Angeles and Pittsburgh after the same team had already set the previous record of 23.2 Gbit / s a ​​year earlier.

In 2007, a 100 Gigabit / s connection was put into operation from the west to the east coast of the USA. The most important stops include Washington , Chicago , Kansas City , Salt Lake City and Seattle . In addition, a ring was built from Washington to Atlanta and from Atlanta to Kansas City. The main players in the development are Level 3 Communications and the Global Research Network Operation Center (GRNOC) at Indiana University . As a participant (research institute on the route) you can connect to the backbone with 51 Mbit / s to 10 Gbit / s. In 2007, the researchers described the standard Internet as “second-class mail” compared to Internet2. A connection with up to 100 Gigabit / s is possible in Germany.
