BRAIN is the high speed data net of Berlin’s public institutions for science, education and culture. It came into being on the basis of a decision of Berlin’s Federal State Government of 1994 on the construction and operation of a state-owned glass fiber Metropolitan Area Network.

BRAIN connects more than 150 locations of more than 45 scientific and cultural institutions in Berlin. BRAIN operates 2000 km of the state-owned glass fiber net. It offers the BRAIN network with individual lines with up to 10,000 Mbit/s for high-performance cross-linkage of scientific and cultural institutions of the city for direct IP-data exchange, for high-performance networking of different locations of one institution, and as access point to the intranet of the federal state of Berlin (Berlin’s state net BeLa). Glass fibers and bandwidth to connect two locations of a single institution and glass fibers to link with the national network infrastructure of the DFN-Verein (German National Research and Education Network) for the DFN internet service X-WiN are offered.
