Appendix 16. SANET in Slovakia

Submitted by Tibor Weis

January 2008

The SANET network infrastructure in Slovakia (Figure 57) covers all Slovak Universities and

institutions of Slovak Academy of Science in 23 towns. The network is completely built up on

single mode dark fiber leased among the cities. The Network is configured as three rings

providing full redundancy with transmission speed ranging from 1Gbs to 10Gbps. In the cities,

SANET built up its own optical trunks terminated at SANET PoPs in Cisco Catalyst 6509 Gigabit

Ethernet switches.

In the year 2007 SANET continued to upgrade their backbone to 10Gbps. This process is going to

be finished in the first half of 2008. Then all SANET backbone lines will operate at a speed of

10Gbps.

Figure 57 SANET the Slovak Academic Network in January 2008

In October 2006 the Central European NRENs ACOnet ­ Austria, CESNET ­ Czech Republic

and SANET ­ Slovakia were interconnected by a triangle of dark fibers lit up by advanced

photonic technologies which are able to provide multiple 10Gbps channels, without the in-line

equipment.

This triangle was extended to the PIONIER Network in Bielsko-Biala Poland through the Czech

Republic.
