Realtime Statistics (SLA KPIs)
AMS-IX provides members and customers with statistics on Key Performance Indicators (KPIs): delay, delay variation (jitter) and frame loss. These KPIs are used in our SLA calculations.
The performance KPIs come from 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. Using a separate VLAN on the platform, the probes continuously exchange measurement messages with each other. Measurement frames are sent out at a rate of 10 per second for delay and jitter measurements, and once per second for frame loss measurements.
The values displayed here in real-time are actual values from a single measurement refreshed every minute. This gives an indication of the performance of the network; for the actual SLA reporting AMS-IX uses per-minute averages over each month, excluding announced maintenance.
