Regional Traffic Distribution Calculator
Split monthly traffic across world regions, find the busiest one and size its peak bandwidth from the share.
Inputs
Regional peaks land at different clock times, so each region peaks against its own average.
Busiest Region Traffic
126.00TB/month
Busiest Region
North America
Busiest Region Peak Bandwidth
1.361Gbps
Declared Shares Total
100.0%
North America Traffic
126.00TB/month
Europe Traffic
78.00TB/month
Asia-Pacific Traffic
66.00TB/month
Remaining Regions Traffic
30.00TB/month
Step by step
Values used
Total traffic delivered = 300 TB/month; North America share = 42 %; Europe share = 26 %; Asia-Pacific share = 22 %; Latin America share = 6 %; Africa, Middle East and elsewhere = 4 %; Peak-to-average ratio = 3.50 ×
Regional Traffic Distribution
region traffic = total × region share ÷ sum of shares; region peak Gbps = region TB × 8,000 ÷ seconds in the month × peak-to-average ratio.
Busiest Region Traffic
= 126.00 TB/month
Busiest Region
= North America
Busiest Region Peak Bandwidth
= 1.361 Gbps
Declared Shares Total
= 100.0
North America Traffic
= 126.00 TB/month
Europe Traffic
= 78.00 TB/month
How it works
Shares are normalised rather than trusted, so an input set that adds to 96% or 104% still produces a consistent split. Each region's peak is derived from its own average bit rate, because regional prime times do not overlap — the global peak is always less than the sum of regional peaks. CDN pricing is regional and per-GB rates in Asia-Pacific and South America are often two to four times the North American rate, so the distribution — not just the total — drives both cost and where you place capacity.
Formula
Regional Traffic Distribution
region traffic = total × region share ÷ sum of shares; region peak Gbps = region TB × 8,000 ÷ seconds in the month × peak-to-average ratio.
- sum of shares
- Declared shares are normalised so they always add to 100%
- peak-to-average ratio
- Busy-hour multiple applied to the region's own average
- busiest region
- The region that sets your largest single-region capacity requirement
Frequently Asked Questions
How is Regional Traffic Distribution calculated?
region traffic = total × region share ÷ sum of shares; region peak Gbps = region TB × 8,000 ÷ seconds in the month × peak-to-average ratio. Shares are normalised rather than trusted, so an input set that adds to 96% or 104% still produces a consistent split. Each region's peak is derived from its own average bit rate, because regional prime times do not overlap — the global peak is always less than the sum of regional peaks.
Why does Regional Traffic Distribution matter?
CDN pricing is regional and per-GB rates in Asia-Pacific and South America are often two to four times the North American rate, so the distribution — not just the total — drives both cost and where you place capacity.
What values do I need to enter?
This calculator takes 7 inputs: Total traffic delivered, North America share, Europe share, Asia-Pacific share, Latin America share, Africa, Middle East and elsewhere, Peak-to-average ratio. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
