Broadband science network
The broadband science network ( B-WiN ) was an ATM -based, broadband network that was set up in autumn 1995 and operated by the Association for the Promotion of a German Research Network (DFN-Verein) via the service provider DeTeSystem , which was later merged into T- Systems .
It was put into operation in March 1996 and connected more than 650 institutions at universities and colleges in Germany . The project was funded by the Federal Ministry of Education and Research ( BMBF ).
The B-WiN was set up as a virtual private network ( VPN ) based on the national ATM cross-connect network of Deutsche Telekom ; it is therefore sometimes referred to as the "science intranet". The network initially achieved a transmission speed of 34 Mbit / s, which was increased to 155 Mbit / s in July 1996 and later to 622 Mbit / s. The B-WiN was thus one of the fastest research networks in the world; a research network that was just as fast at 155 Mbit / s only existed in the USA until then .
The WiN was initially connected to the other European research networks with 6 Mbit / s via EuroNET ; USA connectivity was expanded from 7 Mbit / s to 34 Mbit / s at the beginning of 1997. Links to the European research network TEN-155 have existed since February 25, 1999 .
From around 2000 the B-WiN was gradually replaced by the gigabit science network G-WiN . Today the successor, the X-WiN , is in operation.
