The Amsterdam Internet Exchange (AMS-IX) is an Internet exchange point
situated in Amsterdam
, in the Netherlands

s 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.
In 2002, the Netherlands Internet Exchange
was founded as an alternative or backup for the Amsterdam Internet Exchange.
, AMS-IX connected 396 members on 684 ports. The all time peak of incoming traffic was 1.205 Tbit/s and of outgoing traffic 1.203 Tbit/s compared to 0.768 Tbit/s average incoming and outgoing, at January 5, 2011.
The total amount of data transferred by month was (Avg. incoming and outgoing) 75,940 TB in November 2008. By April 2009, it had grown to 124,550 TB, 64% more traffic in a 5 month period.
These traffic speeds make the Amsterdam Internet Exchange the second largest internet exchange in the world, when measured by number of connected members and by internet traffic, before the Equinix

However, since 2009; AMS-IX platform has migrated from a pure Layer2 network to a VPLS/MPLS network (using Brocade hardware) in order to cope with future growth (this is AMS-IX version 4).
AMS-IX members connect to the platform with 10, 100 Mbit/s, 1G or 10 Gbit/s Ethernet connections, or using multiple gigabit

BigIron 15000 or RX-8 network switch
es. 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.
With the new VPLS/MPLS setup; the BigIron RX and legacy BigIron 15000 are no longer in-use. AMS-IX has migrated all the hardware to the MPLS-capable MLX platform. Stub switch is either MLX-8, MLX-16 or MLX-32.
Since May 2011, AMS-IX engineers have started testing 100GE along with LimeLight Network.
Internet Exchange Point
An Internet exchange point is a physical infrastructure through which Internet service providers exchange Internet traffic between their networks . IXPs reduce the portion of an ISP's traffic which must be delivered via their upstream transit providers, thereby reducing the average per-bit...

Network
The AMS-IX platform is continually evolving due to its rapid growth in traffic and number of connected member ports. Up until end of 2009, it is using a redundant hub-spoke architecture using a core switch and multiple edge switches. 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 VSRPVirtual Switch Redundancy Protocol
