In this section, we propose a distinction between different types of traffic by source or destination. The figure below attempts to illustrate the distinctions in terminology.

Traffic figure

T1 - all traffic from customer sites
T2 - all traffic to customer sites

T3 - all traffic to external networks
T4 - all traffic to the NREN backbone

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

3.1. Estimate of the total amount of external traffic in 2005 as defined in the picture above.
Traffic type Total amount of traffic in 2005 in Terabytes
T3 63.6
T4 77.4
3.2 Estimate of the total amount of traffic in Terabytes in 2005 of the other two types of traffic as defined above
Traffic type Total amount of traffic in 2005 in Terabytes
T1 95.4
T2 117.7
3.3 Approximate percentage of T3 and T4 traffic to/from the Commercial Internet:
Traffic type Total amount of traffic in 2005 in Terabytes
T3 80.0%
T4 80.0%
3.4 Volume of traffic to/from the network in January 2006 (in Terabytes):
Traffic type Total amount of traffic in January 2006 in Terabytes
T3 9.932
T4 11.354
T1 11.987
T2 14.736
3.5 Rough 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 100.0 90.0 50.0 100.0 0.0
some or moderate plain 0.0 5.0 30.0 0.0 100.0
% of institutions experiencing serious congestion angry 0.0 5.0 20.0 0.0 0.0
Total (should be 100%) 100 100 100 100 100
3.6 Activities to promote the use of IPv6:
AMREJ was a host of the IPv6 workshop in SEE region. Workshop was held on Kopaonik in March 2006.
3.7 Does the network support IPv6 multicasting?
( )Yes, on an experimental basis
( )Yes, as a production service
(x)Not yet, but we are planning to introduce it in the next year or two
( )We do not plan to support this in the foreseeable future
