The Vienna Internet eXchange is present at two different co-locations within Vienna. One of them is at Vienna University in the center of the City (1st district). The second location is at Interxion Austria in the 21st district in the north of the city.
VIX uses the same state-of-the-art Ethernet switching technology at both locations:
- Foundry Networks BigIron RX-16 non-blocking high-performance 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 or both sites/switches with up to 10-Gigabit-Ethernet/port
- Local port channels supported (directly connected, colocated routers only)
- Only one MAC address allowed per port or port channel
- Enforced port security automatically shuts down misbehaving ports
- IPv4 and IPv6 peering supported on the same peering-LAN using BGP4 routing-protocol
- sFlow based Peering Traffic Matrix
Configuration
ISPs @ VIX install and operate their own routing infrastructure. Each ISP has to establish bilateral BGP peerings with other parties he is interested to peer. The appropriate routing registry for the documentation of VIX peerings is the RIPE Database.
