IP Transit is a service that provides customers with Internet access through the Mevspace network. The service is intended for customers who require reliable Internet connectivity and the ability to exchange routing information using BGP 1, including support for their own ASN 2 and IP address space.
Open port and commitment
As part of the service, the customer receives an open port with a specified maximum capacity, for example, 100 Gbps. Open port 3 defines the maximum amount of bandwidth 4 the customer can use.
Regardless of the port's maximum capacity, a commitment 5 is defined. This is the minimum bandwidth level covered by a fixed fee, regardless of actual usage. For example, for a 100 Gbps port, the commitment may be 5 Gbps.
At the same time, the customer can use bandwidth above the commitment, up to the maximum port capacity, with usage measured according to the 95th percentile method.
Billing based on the 95th percentile
When bandwidth usage exceeds the commitment, the 95th percentile 6 method may be used to determine the billable usage level.
Throughout the billing period, bandwidth usage is measured at regular intervals. The highest 5% of measurements are then discarded. The highest value among the remaining 95% of measurements is used as the billable usage level.
This approach allows customers to use the available bandwidth flexibly and handle temporary traffic spikes without having to permanently contract the maximum port capacity.
If the value calculated using the 95th percentile is lower than the contracted commitment, the commitment level is still used for billing.
Flexibility without permanently paying for maximum bandwidth
The model based on an open port, commitment, and the 95th percentile allows customers to use high bandwidth when needed without having to permanently contract the port's maximum capacity.
Short-term increases in traffic, known as traffic spikes, are excluded as part of the highest 5% of measurements. This means that individual or short-lived traffic spikes do not automatically result in the customer being billed based on the highest bandwidth usage reached during the month.
At the same time, the 95th percentile method reflects the customer's actual sustained bandwidth usage. If high bandwidth usage continues for a sufficiently large portion of the billing period, it may affect the final billable usage level.
Glossary
-
BGP (Border Gateway Protocol) - a protocol that allows networks to exchange routing information over the Internet and determine how traffic should be routed. ↩
-
ASN (Autonomous System Number) - a unique number that identifies a network on the Internet. Having its own ASN allows the customer to independently manage their BGP routes. ↩
-
Open port - a port whose maximum capacity defines the highest bandwidth level available to the customer, e.g. 100 Gbps. ↩
-
Bandwidth - the amount of data that can be transmitted through a port within a given period of time. ↩
-
Commitment - the minimum bandwidth level for which the customer pays a fixed fee. Regardless of actual usage, the billed amount cannot fall below this level. ↩
-
95th percentile – a method of measuring bandwidth usage in which the highest 5% of measurements are excluded, and the highest value among the remaining measurements is used for billing. ↩
