History

SURFnet has deployed a series of network generations in an overbuilt manner. The initial SURFnet network was based on 9.6 kbit/s and 64 kbit/s X.25

 protocol. SURFnet2 was established in 1989 and delivered TCP/IP over an X.25 network. The SURFnet3 network delivered native TCP/IP via leased lines and became operational in 1991, mainly consisting of 64 kbit/s and 2 Mbit/s lines. In 1994 SURFnet4 was developed based on ATM

 and, later on SDH, links. SURFnet5 was developed from 1999 onwards on a 10 Gbit/s DWDM infrastructure, with access links of 100 Mbit/s and 1 Gbit/s.

Current network

SURFnet6, the sixth generation of the SURFnet network, was taken into operation at the beginning of 2006. This new network not only provides the 750,000 users in higher education and research with high-quality Internet facilities, but also provides them with "lightpaths".

Lightpaths are direct connections between two nodes in the network without the need for routers. Lightpaths are characterised by very high capacity (1 to 10 Gbit/s), quality and reliability. See also http://www.netherlight.net

Services

SURFnet provides services on all layers of its network. Services include authentication services, such as eduroam
