Compendium 2014 (for ARN)

Welcome to the NREN Compendium. The information gathered here contributes to the wealth of knowledge accumulated over decades. Through analysis of this data we can demonstrate the evolution of the NREN community and provide insight into an exciting future ahead.

Answers for the current year will be made public once a sufficient number of questions have been answered. Please note that some answers may be incomplete.

In the context of this questionnaire the term CORE should be taken to mean usable backbone capacity. If your network does not have a backbone core (for instance because it is a star network) please report the maximum capacity into the central node of your network.

Some NRENs have dark fibre with a very high theoretical capacity. In that case, we would like to know the usable IP capacity.

Saved! ✔

This could either be the same or different from the answer above, depending on your network architecture. (Please ALWAYS answer this question.)

Saved! ✔

Note that we are interested in the capacity for production purposes, not in any additional links that may be there for the purpose of giving resilience. Some of your capacity to your regional backbone may be used for transiting to intercontinental services; please do NOT subtract for that.

In the question below, with cross-border (dark) fibre links, we specifically mean those links that have been commissioned or established by the NREN from a point on the network that is near the border to another point near the border on the network of a neighbouring NREN.

For every link, please provide the following information:

Link name: From where To where: Link capacity in Gb/s: Is this a Cross-Border dark Fibre Link?

Please give a descriptive outline of the major initiatives that relate to the development of the underlying network that you might expect to see on your network over the next 2-5 years. It would be helpful if you could associate an approximate level of confidence to each of these predictions: QUITE CERTAIN, LIKELY, UNCERTAIN. (Please ALWAYS answer this question.)

In this section, we propose a distinction between different types of traffic by source or destination. The figure below illustrates the terminology used in the questions below.

T1 - all IP traffic from customer sites and the NREN
T2 - all IP traffic to customer sites and the NREN

T3 - all IP traffic leaving the NREN
T4 - all IP traffic entering NREN

External traffic = all traffic to the NREN's regional backbone, the commercial Internet, Internet exchanges, etc. (made up of T3 and T4 above)
Note: all IP traffic includes both IPv4 and IPv6 traffic.
