The Vienna Internet eXchange
The Vienna Internet eXchange (VIX) is operated by the Vienna University Computer Center since 1996. It is a neutral peering infrastructure for National Research & Education Networks (NRENs), Internet Service Providers (ISPs), Content Delivery Networks (CDNs) and Content Providers in Austria and the Central and Eastern European Region for the exchange of Internet traffic at the national and international level.
As a founding member of the Euro-IX Association, VIX has been developing its policies and technologies according to European Best Current Practices. For some time now, the Vienna Internet eXchange has also been offering remote peering options for participants from other regions if they do not want to operate their routers in Vienna.
VIX participants may connect to VIX at one, two or all three locations. The redundant VIX infrastructure at all sites is provided and operated by the University of Vienna, ensuring a neutral, robust and non-profit peering environment for all participants.
VIX participants need to agree on bilateral peering arrangements for traffic exchange. There is no obligation to exchange traffic with all other participants. The required routing protocol for peerings is BGP4. The appropriate routing registry for the documentation of VIX peerings is the RIPE Database; furthermore the use of PeeringDB is recommended. Currently, Switched Ethernet (10GBASE-LR, 100GBASE-LR4) is used as common exchange medium (see Technology).
How to become a VIX participant is explained in VIX Participation.
