In this section, a distinction is made between different types of traffic by source or destination. Please refer to the figure below, which illustrates the distinctions in terminology.

Traffic figure

T1 - all traffic from customer sites (outbound)
T2 - all traffic to customer sites (inbound)

T3 - all traffic to external network clouds
T4 - all traffic to the NREN backbone

External traffic = all traffic to GÉANT, the Commercial Internet, Internet exchanges, etc. (made up of T3 and T4 above)

3.1.Estimate of the total amount of traffic (in Terabytes) in 2004 of the types of traffic as defined in the picture above.

Traffic type Total amount of traffic in 2004 in Terabytes
T3 (outbound external traffic)  
T4 (inbound external traffic)  
3.2 T1  
T2  
3.3Approximate percentage of T3 and T4 traffic to/from the Commercial Internet
T3 (outbound external traffic) 0.0%
T4 (inbound external traffic) 0.0%
3.4
Traffic typeVolume of traffic to/from the network in January 2005 (in Terabytes)
T3 (outbound external traffic)  
T4 (inbound external traffic)  
T1  
T2  

3.5Rough estimate of where there is congestion (if any) in the network and of the percentage of the total number of client institutions that are affected by congestion at this level

  Campus LAN MAN or regional network Access Network NREN backbone External Connections
% of institutions experiencing no or very little congestion happy 93.0 0.0 98.0 100.0 100.0
some or moderate plain 5.0 0.0 1.0 0.0 0.0
% of institutions experiencing serious congestion angry 2.0 0.0 1.0 0.0 0.0
total 100 0 100 100 100

3.6 Is the NREN aware of performance bottlenecks that are likely to be caused by multiple management domains? If so, examples of this:

On-going difficulties in establishing end-to-end services caused by badly designed
and incorrectly managed firewall equipment
at certain end-sites.

IPv6

3.7Volume of IPv6 traffic to/from the network in January 2005 (in Terabytes)

T3 (outbound external traffic) 0.000 TB
T4 (inbound external traffic) 0.0 TB
3.8Best estimate of the percentage of total traffic that is currently IPv6 traffic 0.0 %
3.9Estimate of the increase of IPv6 traffic across the network in the next 1- 2 years 0.0 %

3.10Is the NREN funding or participating in IPv6-related activities other than providing IPv6 connectivity?

Through NORDUnet IPv6 group

3.11Does the network support IPv6 multicasting, or does it have plans to do so?

No

3.12IPv6 services the NREN supports

FTP / DNS
