Topology

All over Austria, ACOnet in co-operation with some major participants entertains Points of Presence (PoPs). The routers at our PoPs are interconnected via a physical network specifically dedicated to ACOnet. These routers, which are also capable to provide Layer 2 services, connect the participants' routers.

  • The locations Krems, St. Pölten, St. Johann/Pongau, Bregenz, Dornbirn, Leoben, Wiener Neustadt, and Eisenstadt are each connected to their two nearest PoPs with 10 Gbps links.

  • To increase availability, two interconnected PoPs are being entertained at each location in Linz, Salzburg, Innsbruck, Klagenfurt, and Graz. Each of these two PoPs is linked to one of the two Viennese PoPs via geographically separated and redundant ways. This ensures that even in case of a possible interruption a Viennese PoP can still be reached directly.

  • The core routers at the two Viennese PoPs are interconnected by two redundant fibers; 100 Gbps and a 40 Gbps backup way. All other PoPs are connected to these core routers. They also provide international and commodity connectivity for ACOnet's participants.

Additionally, since 2015 we operate the so-called "LWL-Ring WienMitte/WienWest", a redundant fiber ring interconnecting several major Viennese cultural institutions. For more information see Community.
