## Answer

- The 95th percentile is a widely used mathematical calculation to evaluate the regular and sustained utilization of network resources.
- The reason this statistic is so useful in measuring data throughput is that it gives a very accurate picture of the maximum traffic generated on a given interface.
- The 95
^{th}percentile is the highest value left when the top 5% of a numerically sorted set of collected data is discarded. - It is used as a measure of the peak value used when one discounts a fair amount for transitory spikes. This makes it markedly different from the average.
- F5 Silverline calculates the bandwidth consumption via 95th percentile. This measurement unit is used to understand the amount of clean traffic our customers expect normally.
