Enter the data link’s capacity (bandwidth) in bits per second and the round-trip delay time in seconds to calculate the bandwidth-delay.
Bandwidth Delay Product Formula
The following formula is used to calculate the bandwidth-delay product.
BDP = B * D
- Where BDP is the bandwidth-delay product
- B is the bandwidth or data link capacity (bits per second)
- D is the round-trip delay (seconds)
Bandwidth Delay Product Definition
Bandwidth delay product is a term used in data communication to describe the product of the bandwidth (link capacity) and the round-trip delay time. This is a measure of the maximum amount of data on a network circuit at any given time.
Bandwidth Delay Product Example
How to calculate a bandwidth delay product?
- Next, determine the round-trip delay time.
It’s important that this is round-trip and not single distance delay time.
- First, determine the data link capacity.
Measure the total bandwidth in bits per second.
- Finally, calculate the bandwidth delay product.
Calculate the BDP using the equation above.
Large Bandwidth-delay products in networks are often considered ones greater than 12,500 bytes.
