The Amsterdam Internet Exchange (AMS-IX) is an Internet exchange point situated in Amsterdam, in the Netherlands. AMS-IX is a fast growing, non-profit, neutral and independent peering point. The AMS-IX is the largest Internet Exchange in the world, when measured both by number of members and by traffic. During 2007 the overall system availability was over 99.999%, and ended the year with 1.7 Terabits/s capacity over 469 ports.[1]

History
| Year | Peak traffic |
|---|---|
| 2002 | 12 Gbit/s[2] |
| 2003 | 21 Gbit/s[2] |
| 2004 | 48 Gbit/s[3] |
| 2005 | 120 Gbit/s[4] |
| 2006 | 220 Gbit/s[4] |
| 2007 | 374 Gbit/s[1] |
In February 1994, a layer 2 shared infrastructure, used between academic institutes, was connected with CERN to exchange traffic. Other internet service providers were allowed to connect and the name AMS-IX was first used. In 1997, the AMS-IX Association was founded by twenty of the connected internet service providers and carriers.[4]
In 2002, the Netherlands Internet Exchange was founded as an alternative or backup for the Amsterdam Internet Exchange.[5]
As of October 1, 2008, AMS-IX connected 303 members on 569 ports[6] and the all time peak of incoming traffic was 482.110 Gbit/s and of outgoing traffic 481.568 Gbit/s.[7] This makes the Amsterdam Internet Exchange the largest internet exchange in the world, when measured by number of connected members and by internet traffic, before the Deutscher Commercial Internet Exchange[8] and the London Internet Exchange.[9]
Points of presence
AMS-IX members are able to connect at six locations, all located within Amsterdam:
- SARA (Science Park Amsterdam, Oost/Watergraafsmeer)
- NIKHEF (Science Park Amsterdam, Oost/Watergraafsmeer)
- GlobalSwitch (Slotervaart)
- TelecityRedbus (Amsterdam Zuidoost)
- euNetworks (Amsterdam Zuid)
- Equinix AM1 (Amsterdam Zuidoost) (fall 2008[10])
Via high speed VPN links access to the shared LAN of the AMS-IX is also possible from several locations in the Netherlands. Some regional peering projects and telco's offer these services.[11]
Network
The AMS-IX platform is continually evolving due to its rapid growth in traffic and number of connected member ports. Currently it is using a redundant hub-spoke architecture using a core switch and multiple edge switches.[12] This double-star topology brings the advantage of being able to perform maintenance on the network without any impact on customer traffic, and to anticipate on fiber and equipment problems by (automatically) switching to the backup topology as soon as a failure in one of the active components occurs. The active switching topology star is determined by means of the VSRP protocol.
AMS-IX members connect to the platform with 10, 100 Mbit/s, 1 or 10 Gbit/s ethernet connections, or using multiple gigabit or 10 gigabit aggregated ports, utilizing the 802.3ad standard. Gigabit ethernet and lower speed ports are directly connected to Foundry Networks BigIron 15000 or RX-8 network switches. 10 Gigabit member ports are connected to Glimmerglass Systems photonic switches which maintain an optical connection to the stub switch on the currently active side of the network, following the VSRP protocol. For each 10 Gigabit port there is an active and a backup stub switch, for which BigIron RX-8, RX-16 or NetIron MLX-16 switches are used. The core consists of two Foundry NetIron MLX-32 switches, to which all edge switches are connected using 10 gigabit aggregated connections and WDM technology.
Connected servers
Since August 1, 2003, a mirror of the K-root nameserver is available on AMS-IX and its backup NL-ix.[13]
In December 2007, Wikimedia Foundation and AMS-IX joined forces for the "good of the internet". AMS-IX provides a Gigabit Ethernet connection at no cost to Wikimedia's Amsterdam datacentre.[14]
