- VIX1 is located at the University of Vienna in the city centre (1st district),
- VIX2 at Interxion in the north of Vienna (21st district), and
- VIX3 at e-shelter in the south of Vienna (10th district).
These locations are interconnected via redundant, diversely routed fiber optic cables.
VIX uses the same state-of-the-art Ethernet switching technology at all three locations:
- Brocade MLXe-32 non-blocking high-performance VPLS switches
- redundant switch fabrics and management processors
- redundant power supplies
- redundant power feeds (mains, UPS + generator)
- interconnected by diversely routed fibre optic cables
- participants may connect to either one, two or all three sites with up to 100 Gbps Ethernet per port
- local port channels supported (directly connected, co-located routers only)
- only one MAC address per port or port channel allowed
- port security mechanisms
- IPv4 and IPv6 peering supported on the same peering LAN using the BGP4 routing protocol
- sFlow based Peering Traffic Matrix
The Internet Service Providers (ISPs) connected to VIX install and operate their own routing infrastructure. The appropriate routing registry for the documentation of VIX peerings is the RIPE Database.
