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 VSRP protocol. This topology is AMS-IX version 3.

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 1, 10, 100 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 Brocade - 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 Brocade 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.

Famous quotes containing the word network:

    A culture may be conceived as a network of beliefs and purposes in which any string in the net pulls and is pulled by the others, thus perpetually changing the configuration of the whole. If the cultural element called morals takes on a new shape, we must ask what other strings have pulled it out of line. It cannot be one solitary string, nor even the strings nearby, for the network is three-dimensional at least.
    Jacques Barzun (b. 1907)

    Of what use, however, is a general certainty that an insect will not walk with his head hindmost, when what you need to know is the play of inward stimulus that sends him hither and thither in a network of possible paths?
    George Eliot [Mary Ann (or Marian)

    How have I been able to live so long outside Nature without identifying myself with it? Everything lives, moves, everything corresponds; the magnetic rays, emanating either from myself or from others, cross the limitless chain of created things unimpeded; it is a transparent network that covers the world, and its slender threads communicate themselves by degrees to the planets and stars. Captive now upon earth, I commune with the chorus of the stars who share in my joys and sorrows.
    Gérard De Nerval (1808–1855)
