To support open IP traffic exchange in Norway, a set of neutral IP exchange points (IXPs) has been established by the University of Oslo. Organizations who want to exchange IP traffic can connect their equipment to one or more of these IXPs.
The term NIX is short for "Norwegian Internet eXchange" and refers to six independent exchange points for IP-traffic in Norway:
NIX1 is the primary site for the Norwegian Internet Exchange. NIX1 is co-located at three sites in Oslo.
NIX2 is the primary site for redundancy located in downtown Oslo.
The remaining four sites are regional sites intended for local use.
All six IXPs are isolated, without any physical or logical interconnections.
The term NIX refers to all of the six IXPs.
