Organisation:
Users / Clients Network Traffic Funding & Staffing Services Basic Information Organisational Information
2.1Number of PoPs on the network (defined as the number of sites where the NRENs manages routing or switching equipment) 4
2.2Number of managed links (that carry production traffic) between PoPs on the network 3
2.3Estimate of the bandwidth*distance products [in Gbit/s*km] for all the NREN's managed links. (SUM linki * bandwidth(linki) 33.90
2.4Current 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
(x)> 155 Mb/s =< 622 Mb/s
( )> 622 Mb/s =< 1.2 Gb/s
( )> 1.2 Gb/s =< 5 Gb/s
( )> 5 Gb/s =< 10 Gb/s
( )> 10 Gb/s
2.5Expected increase in two years' time between 622 Mb/s and 1.2 Gb/s

2.10Technology used on the core network

Technology Current (tick or give estimated percentage of the length of the network in km in point-to-point distances:) Expected situation in early 2007
ATM    
ATM over SDH    
SDH 80 60
PDH    
Ethernet 20 10
Gigabit Ethernet   10
DWDM   20
Packet over SONET    
Other:      

2.11Does the NREN have IRUs or does it own or lease dark fibre? Percentage of the network (in kilometres in point-to-point distances) which is dark fibre.

Owned, % of network IRUs, % of network Leased, % of network
Present situation 0.0 0.0 0.0
Expected situation, early 2007 0.0 0.0 0.0
