Formula and methodology
Formula: BDP bits = bandwidth × 10⁶ × RTT/1000; BDP bytes = BDP bits/8.
The bandwidth-delay product estimates how much data can occupy the network path during one round trip.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Bandwidth — Mbps; minimum 1.0E-6; maximum 1000000000
- Round-trip time — ms; minimum 0; maximum 1000000
Worked example
| Input | Value |
|---|---|
| Bandwidth | 100 |
| Round-trip time | 50 |
BDP = 5,000,000 bits = 625,000 bytes.
Assumptions and limits
- Bandwidth is decimal megabits per second and delay is milliseconds.
- The link is treated as continuously available at the entered rate.
- Protocol overhead, packet loss, acknowledgements, and application buffering are not modeled.
