The service availability is the total period per calendar year of availability of its infrastructure in one city (all customer ports). The objective for France-IX is to deliver to its customers an availability of at least 99,995% per year (non contractual). France-IX is running two IXPs, one in Paris, one in Marseille: the availability is calculated separately for both, as the IXPs are independent and not interconnected.
The following events are excluded from availability calculation:
The service is considered as unavailable when the customer is not able to reach at least 10% of France-IX customers, for a period of time longer than 10 consecutive seconds or the inability to send or receive traffic across France-IX infrastructure.
Every month, the availability is measured, in order to consolidate the annual availability. The total time is measured in minutes.
|Availability =||Total time ∑ - downtime (maintenances + outages)||x 100|
|Total time ∑ - downtime (maintenances)|
The availability is measured based on tickets generated by France-IX NOC and on measures collected from the monitoring probes. It is displayed in real time and accessible online at anytime by the customer on the France-IX customer portal.
The objective for France-IX is to deliver to its customers the following target values (non-contractual):
For Round-trip Delay, the value indicated is the maximum delay between two PoPs, taking into consideration there can be 80km between two PoPs. France-IX has deployed probes on all its PoPs. Round-trip delay, jitter and frame loss are measured and monitored permanently:
Measurements are published on France-IX’s customer portal so that customers can check at any time the overall quality of service. Measurements are used by France-IX Technical team and France-IX NOC to also detect in a proactive way some possible issues before they impact the Service.
In addition to such KPIs, France-IX is also monitoring the level of traffic on each customer connection, and the optical levels of each port, to prevent any degradation of quality of service due to a congestion on a customer port and some errors seen at the optical layer due to a faulty optic.
Finally, backbone links are overprovisioned to avoid any risk of congestion. France-IX Technical team checks permanently these links and launch a capacity upgrade if the load exceeds 40%.
