The information below regards the entire network that is managed by the NREN, excluding links outside the national territory.

2.1 Number of PoPs on the network (A PoP is defined here as a point on the NREN backbone which can connect client networks or aggregations of client networks such as MANs, or external networks):
8
2.2.1 Number of managed sites on the network (i.e. the number of sites where the NREN manages routing or switching equipment):
10
2.2.2 Number of managed links (that carry production traffic) between the managed sites on the network:
26
2.3 Aggregate capacity of the network. This figure is obtained by adding the bandwidth*distance products [in Gbit/s*km] for all the NREN's managed links (excluding links outside its national territory). Note that in many cases, the figure is a rough estimate.
1200.00
2.4 Current typical core usable backbone capacity on the network (excluding backup links):
( )2 Mbit/s or below
( )> 2 Mb/s =< 34 Mb/s
( )> 34 Mb/s =< 155 Mb/s
( )> 155 Mb/s =< 622 Mb/s
(x)> 622 Mb/s =< 1.2 Gb/s
( )> 1.2 Gb/s =< 5 Gb/s
( )> 5 Gb/s =< 10 Gb/s
( )> 10 Gb/s
2.5 Expected situation in two years' time:
( )2 Mbit/s or below
( )> 2 Mb/s =< 34 Mb/s
( )> 34 Mb/s =< 155 Mb/s
( )> 155 Mb/s =< 622 Mb/s
( )> 622 Mb/s =< 1.2 Gb/s
( )> 1.2 Gb/s =< 5 Gb/s
(x)> 5 Gb/s =< 10 Gb/s
( )> 10 Gb/s
