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 by number of members, or by traffic.

[edit] History

Year Peak traffic
2002 12 Gbit/s[1]
2003 21 Gbit/s[1]
2004 48 Gbit/s[2]
2005 120 Gbit/s[3]
2006 220 Gbit/s[3]
2007 413 Gbit/s

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.[3]

As of February 9, 2008 AMS-IX connected 293 members on 509 ports[4] and the all time peak of incoming traffic was 411.065 Gbit/s and of outgoing traffic 413.142 Gbit/s.[5] 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[6] and the London Internet Exchange.[7]

[edit] Locations

AMS-IX members are able to connect at six locations, all located within Amsterdam:

[edit] Network

The AMS-IX platform is continually evolving due to its rapid growth in traffic and number of connected member ports. Currently it's using a redundant hub-spoke architecture using a core switch and multiple edge switches.[10]. 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.
