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.
