95th Percentile Billing

CoreXchange offers a burstable bandwidth mesh utilizing the 95th percentile method of billing.  Burstable billing is based on peak usage and allows usage to exceed bandwidth commitment levels for brief periods of time without having to purchase a higher commitment level than needed.

With 95th percentile billing, network usage is measured and logged every 5 minutes throughout the month.  At the end of the month, the log of usage samples is sorted in descending order and the highest 5% is disregarded.  The next highest usage sample is the 95th percentile value and is the bandwidth usage for the month.  This essentially gives a non-penalized bursting period of approximately 36 hours a month.

In this example, the red line shows the 95% billing marker.  All bandwidth measurements above the red line are considered the highest 5% will be discarded and not billed.  Bandwidth below the red line indicates the lowest 95% of the traffic.  95% percentile billing gives the benefit of burstable bandwidth.  This example shows network usage upwards of 92 Mbps while billing will remain at 20.81 Mbps.
