The story
During the 1990s, the so-called national networks for science, research and education were established in the majority of European countries, the aim of which was to serve the specific needs of scientific and academic communities. The beginning of academic networks in the Czech Republic dates back to 1991, when a mainframe computer was installed in the computing centre of the Czech Technical University, which was then connected to the EARN (European Academic Research Network) academic network. The transfer speed was 9.6 kbit/s, and it was the first opportunity to access the global network infrastructure from the country. In 1992, the transfer speed doubled and was divided into two independent channels. One channel continued to be used for the EARN network, and the other one was used for the Internet. The Czech Republic was officially connected to the Internet on 13 February 1992. The academic community showed a huge interest in being connected to the network. Representatives of universities and institutes of the Academy of Sciences met to discuss the technical solutions for the network that would be used to connect their institutions. The result was a project called FESNET (Federal Education and Scientific NETwork), which was supported by the Department of Education. After the split of Czechoslovakia in 1993, the CESNET project was modified, and the CESNET network was put into operation at the beginning of 1993. From 1992 to 1999 CESNET supported a commercial network, but this activity was sold in early 1999 and from that time CESNET was fully focused on academic networking.
