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?

**First, determine the data link capacity.**Measure the total bandwidth in bits per second.

**Next, determine the round-trip delay time.**It’s important that this is round-trip and not single distance delay time.

**Finally, calculate the bandwidth delay product.**Calculate the BDP using the equation above.

## FAQ

**What is a high bandwidth-delay product?**

Large Bandwidth-delay products in networks are often considered ones greater than 12,500 bytes.
