The Peering Service is supported by NORDUnet’s global IP backbone and extended peering infrastructure. Our aim is to provide the European NREN community with a neutral high quality IP service towards the commercial Internet and content providers. Through joint collaboration with the European NREN community, we can improve the service for the benefit of all participants and thereby increase the likelihood of establishing new peers.


The Peering Service is available to all members of the European NREN community


Two connectivity options are available: a 10-Gbps or a 100-Gbps Ethernet port. The 10/100-Gbps ports can be either flat rate or metered.

Network reliability and quality:

  • Quarterly service availability is 99.9% for single connected and 99.995% for redundant connected services.
  • Average packet loss is less than 0.01%.
  • Average round trip delay is:

Inter Europe (excl. Iceland)           < 40ms

Europe Mainland to US East           < 60ms

Inter US                                        < 50ms

Technical details:

Full service:

The full Peering Service provides you with a standard full Internet table allowing for global connectivity. Where available the traffic delivery is leveraging on our direct peers and an upstream network is used for the remaining destinations.

Partial service:

The partial Peering Service provides you with a subset of the global Internet routing table. Only the prefixes learned from our direct peers are provided and prefixes are only announced to those peers. We learn roughly 80% of the global table from direct peers, and we will continue to increase this percentage. Access to global connectivity would require an alternative upstream network.

Connection options:

Route filtering:

An exact match IP prefix-list filter will be installed on your BGP sessions. The filter will be populated according to information extracted from your provided ASN Set/Macro. Separate filters for IPv4 and IPv6 prefixes are maintained and updated automatically every 24 hours, or at request. In order for new prefixes to become globally visible behind NORDUnet a route-object associated with your ASN Set/Macro must be defined. Based on the number of defined prefixes in the ASN Set/Macro a 10% increase of the absolute number will be applied as a maximum-prefix setting on the BGP session.

To secure the best possible commodity internet service for the Nordic research and educational networks NORDUnet A/S operates a global IP network and is currently present at the following Internet eXchange points:

  • AMS-IX in Amsterdam
  • NL-IX in Amsterdam
  • Asteroid International in Amsterdam
  • DE-CIX in Frankfurt
  • ECIX in Frankfurt
  • ECIX in Hamburg
  • DIX in Copenhagen
  • Netnod in Copenhagen
  • Equinix in Ashburn (Washington D.C.)
  • Equinix in Chicago (IL)
  • Equinix in Palo Alto (CA)
  • LINX in London
  • LONAP in London
  • NETNOD in Stockholm
  • STHIX in Stockholm
  • NIX in Oslo
  • NOTA in Miami
  • FL-IX in Miami
  • NYIIX in New York
  • RIX in Reykjavik

We are also present at selected R&E Focused Internet Exchange points

  • Netherlight in Amsterdam
  • GÉANT Open in London
  • NOX-HEL in Helsinki
  • MANLAN in New york
  • WIX in Washington
  • PacificWave in California
  • MOXY in Montreal

Other than public-peering on exchange points we do have multitude of private peerings on dedicated circuits with big service providers as well as cloud providers. A selection of redundant private peers on dedicated circuits are;

  • Amazon (with on-net access to AWS direct-connect)
  • Microsoft (with on-net access to Azure on-premises)
  • Akamai (with a on-premises caching infrastructure to support local offloading)
  • Google (with a on-premises caching infrastructure to support local offloading)
  • Facebook
  • Netflix
  • Dropbox
  • Apple
  • Twitch.TV
  • Edgecast
  • Valve Software
  • Vodafone Global

…And many more.

Dedicated private peerings is an area of focus for both us and the market in general so this is expected to grow significantly.
