What Is Enhanced 95th Percentile Bandwidth Billing?
The enhanced 95th percentile bandwidth billing mode allows you to use more bandwidth after you pay for the baseline bandwidth. You are billed based on the required duration and the bandwidth volume after eliminating some top sampled usage from a billing period.
Prerequisite
To use the enhanced 95th percentile billing mode, the following requirements must be met:
- Your level is greater than or equal to V4.
- You can select this billing mode when purchasing a shared bandwidth.
- The minimum bandwidth you can purchase is 300 Mbit/s.
Pricing Details
Billing formula: Monthly peak bandwidth x Monthly peak bandwidth price x Shared bandwidth in-use days/Calendar days of a month.
Billing mode: The enhanced 95th percentile bandwidth is billed on a pay-per-use basis, and does not require prepayment. The monthly fee is settled at the end of each calendar month.
Monthly peak bandwidth price: The price is preset and does not vary according to the number of days in a calendar month.
Shared bandwidth in-use days = Number of collected bandwidth values in a month/288.
Monthly peak bandwidth: The monthly peak bandwidth is calculated based on the enhanced 95 percentile billing mode in which some peak bandwidth values discarded. It must be higher than the monthly baseline bandwidth.
Daily baseline bandwidth: Daily baseline bandwidth = Baseline percentage x Shared bandwidth. The baseline percentage is 20%.
In enhanced 95 percentile billing mode, the shared bandwidth can be adjusted in real time, and the adjustment takes effect immediately. After the shared bandwidth is adjusted, the baseline bandwidth changes accordingly. The daily baseline bandwidth is calculated based on the maximum baseline bandwidth set for a day. For example, if the bandwidth is adjusted from 100 Mbit/s to 300 Mbit/s and then to 200 Mbit/s during a day, the daily baseline bandwidth is 60 Mbit/s (300 x 20%).
Monthly baseline bandwidth: The bandwidth can be adjusted frequently to suit the traffic requirements during a month.
The monthly baseline bandwidth is calculated based on the following formula (only the integer is retained in the calculated result): Monthly baseline bandwidth = (Baseline bandwidth 1 x Number of days using baseline bandwidth 1 + Baseline bandwidth 2 x Number of days using baseline bandwidth 2 + ... + Baseline bandwidth n x Number of days using baseline bandwidth n)/Number of days using all baseline bandwidths in a month.
- Daily peak bandwidth
- Inbound and outbound traffic data is collected every five minutes.
- The averages of both inbound bandwidth and outbound bandwidth within five minutes are calculated, and the larger one is used as the bandwidth for that collection.
- After all meter readings within a day are obtained, they are sequenced in descending order. The top four peak bandwidth values are discarded, and the fifth peak bandwidth value is used as the daily peak bandwidth.
Figure 1 Daily peak bandwidth
If less than five peak bandwidth values are obtained in a day, the last value in the peak bandwidth sequence is used as the daily peak bandwidth. The daily peak bandwidth is an integer (any fractional parts are discarded).
- Monthly peak bandwidth
At the end of each month, the daily peak bandwidth values are sequenced in descending order. The average of the top five daily peak bandwidth values is the monthly peak bandwidth (only the integer is retained and fractional parts are discarded).
Figure 2 Monthly peak bandwidth
If less than five daily peak bandwidth values are obtained, the average of all the daily peak bandwidth values in the month is the monthly peak bandwidth. The monthly peak bandwidth is an integer (any fractional parts are discarded).
The larger value between the baseline bandwidth of the month and the average of daily peak bandwidth values is used as the monthly peak bandwidth. If the baseline bandwidth of a month is greater than the average of the daily peak bandwidth values, the monthly peak bandwidth is equal to the baseline bandwidth of the month. Otherwise, the monthly peak bandwidth is equal to the average of daily peak bandwidth values.
