AMS-IX

To meet the needs of its many and diverse members, AMS-IX has one of the most sophisticated networks found in an IXP as well as a particularly detailed set of policies, procedures and traffic metrics.

To fill the gap between 1, 10 and 100 Gbit/sec port offerings, AMS-IX offers link aggregation for 1 Gigabit and 10 Gigabit Ethernet ports. This technique allows for the bundling of two or more Gigabit Ethernet links into one virtual channel, negating the need for additional routers.

Service-level quality is regularly measured by a trusted third-party, and AMS-IX provides a carrier-grade SLA with service credits up to 100% of the monthly fees upon under-performance. AMS-IX provides members with statistics on key performance indicators: delay, delay variation (jitter) and frame loss. To measure these indicators AMS-IX uses Delay Measurement Messages provided by the ITU-T Y.1731 Ethernet OAM standard.  Every switch in the network has a measurement probe attached to it that exchanges these measurement messages over the platform in a separate VLAN.

AMS-IX technical policies include:

  • 100base and 10base Ethernet interfaces attached to AMS-IX ports must be explicitly configured with speed, duplex or other configuration settings, i.e. they should not be auto-sensing.
  • Because the AMS-IX infrastructure is based on the Ethernet II (or “DIX Ethernet”), standard LLC/SNAP encapsulation (802.2) is not permitted.
  • Frames forwarded to an individual AMS-IX port shall all have the same source MAC address.
  • Use of proxy ARP on the router's interface to the exchange is not allowed.
  • Frames forwarded to AMS-IX ports cannot be addressed to a multicast or broadcast MAC destination address except as broadcast ARP packets and multicast ICMPv6 Neighbour Discovery packets.
  • No traffic for link-local protocols on AMS-IX ports except for ARP and IPv6 ND
  • All new ports activated are first placed in their own separate Quarantine VLAN, together with a monitor port, in order to first ensure proper functioning and configuration of the link.
