​2015 Compendium of NRENs now available


The fifteenth annual GÉANT Compendium of National Research and Education Networks (NRENs) in Europe is now available. The Compendium lays out the work currently being done by NRENs, examining the different contexts in which they operate and explaining important trends in research and education networking that concern them. It's an authoritative reference work for policy makers, funders, NRENs and their users.


This year the Compendium has become an even more interesting read, as experts from across our community have been invited to analyse and interpret the survey results and present key findings using their specialist insight.

This year's edition once more shows some interesting trends:

  • Trend 1: Increasing capacity
    The typical core capacity in most GÉANT partner countries remains at 10 Gb/s with some NRENs implementing 100Gb/s. Because many NRENs have access to dark fibre, which potentially can handle high capacity, they can increase capacity easily and economically. We are seeing a continued strong commitment to deploying dark fibre in the NREN community. Nearly all NRENs reported an increase in the amount of fibre, which potentially allows for more and new flexible service offerings to their customers. GÉANT network IP traffic resumed an upward trend again after a short dip in 2014.

  • Trend 2: Growth in services
    Just like research and education, federations and eduroam are now global in scope: more than a billion times, someone has opened their laptop at another university, college, museum, railway station or airport, and been silently connected to the internet through eduroam; and the eduGAIN interfederation service has now gained almost universal acceptance. As access to services increasingly becomes location independent, the need for security is higher than ever. Compendium data highlights the benefit of an organised response to today's large-scale attacks; networks with mature CSIRTs suffer less disruption. By working together, NRENs are leading improvements in internet security.

  • Trend 3: Growth in staff
    Over the past years infrastructural investments led to savings in transmission costs. In addition, the resulting infrastructural improvements coupled with innovations in the area of authentication and authorisation have enabled a new generation of networked services, which have required some increases in staff size in many NRENs.


Further information

Production of this GÉANT Compendium was overseen by an international review panel and staff of GÉANT, and was financially supported by the European Union through the GN4 Phase 1 (GÉANT) project. As in 2014, this 2015 edition of the Compendium is the product of a global collaboration effort that led to an NREN Common Information Model, which is now being used by regional NREN associations around the world.
