SAS computer network communicates through the fibre optic network SANET II, which connects all university cities in the Slovak Republic. SAS has its organisations in the following regions: Bratislava, Nitra, Tatry, Zvolen (B. Bystrica), Košice. Detached workplaces are also located in Považie. SAS organisations in Slovakia connected by the network are therefore split into 6 regions:
Bratislava (Ivanka pri Dunaji, Trnava) 76 SAS workplaces
Nitra (Mlyňany, Hurbanovo) 7 SAS organisations
Zvolen (Banská Bystrica) 5 SAS organisations
Košice (Michalovce) 14 SAS organisations
Tatry (Poprad, Lipt. Mikuláš) 6 SAS organisations
Považie (Trenčín, Piešťany, Pov. Bystrica, Martin) 5 SAS organisations
Metropolitan SANET II networks are built in regional capitals and connect to local SAS organisations. Bratislava region contains the most complex network due to the Patrónka research campus, where 44 SAS workplaces in 23 buildings are connected. The whole SANET II and SAS network use fibre optics with speeds of 1 Gb/s on the connecting networks and 10 Gb/s on the backbone network of the Slovak Republic.
The backbone network of SANET was updated using fibre optics with a new topology and technology during 2001 and 2002. Local nodes were updated with gigabit switches that use the Ethernet technology. The backbone network was later updated to 10Gb/s technology.
Computing Centre administers the SAS network in the Bratislava region, which also contains the areas of Smolenice, Dobrá Voda (2 SAS organisations connected to the SANET network through a node in Trnave) and a part of the Považie region (2 organisations connected to the SANET network through a node in Piešťany). 29 SAS workplaces are connected to the SAS network in Bratislava and Ivánka pri Dunaji (apart from the Patrónka campus). Of those, 26 workplaces are connected using fibre optics with the speed of 1 Gb/s and 3 SAS workplaces are connected using a radio connection with the speed of 11 and 30 Mb/s.
The buildings in the SAS Patrónka research campus are connect by approx. 5.2 km of optical fibres. The network is connected to TP cables inside the buildings with connection speeds of 1Gb/s or 100 Mb/s that connect to LANs. Workplaces inside the Patrónka campus are connected the SANET backbone network using a CISCO router and a DELL switch, which connect to the backbone with the speed of 10 Gb/s. 35 SAS organisations in 23 buildings are connected and some of the organisations use more than one connection.
SAS Computing Centre is a node of the SANET II backbone network and also provides services to other members of the SANET II association. Currently SAS Computing Centre provides services and connections to 10 members of SANET.
