The AMS-IX is the largest Internet Exchange in the world, when measured by number of members, or by traffic. As of March 29 , 2006 , AMS-IX had 241 connected members on 382 ports; peak traffic rate was 144.2 Gbit/s. NETWORK The AMS-IX is continually evolving, and is currently using a hub-spoke architecture using several photonic switches, as can be seen in the following topology map: {Link without Title} . This topology brings the advantage of being able to perform maintenance to the core network without any impact on customer connections, and anticipate on fiber problems by (automatically) switching to the backup topology thus using another set of fibers. The active switching topology star is determined by means of the VSRP protocol. Members connect to Foundry Networks BigIron 15000 Ethernet Switch es, which provide many speeds: 10baseT/100baseTX, 1000baseSX, 1000baseLX, and 1000baseLH. AMS-IX also offers 10 Gbit/s connections via Glimmerglass System 300 photonic switches which provide resilience between the two VSRP domains by following the active VSRP switch. The 10Gbit/s connections are connected via the photonic switches to aggregating Foundry RX16 and MG8 switches, called stub-switches. AMS-IX provides 10000baseLR and 10000baseER connections. The core consists of Foundry Networks RX16 switches, with redundant power supplies, as all switches are equipped. AMX-IX also offers aggregated links, which were used to provide speeds beyond 1 Gb/s. The bundling of two, 1 Gbit/s ethernet connections could provide speeds of 2 Gbit/s, and so on. While these are still in use, AMS-IX has become the world's first IXP offering 10 Gigabit Ethernet customer ports and has connected multiple customers with aggregated 10Gbit/s connections effectively providing 20Gbit/s connections.
