Bandwidth Delay Product
Estimate how much data can be in transit on a network link based on its bandwidth and round-trip latency.
CalcSimpler Examples
- 100 Mbps with 50 ms ⇒ 625000 bytes
- 50 Mbps with 10 ms ⇒ 62500 bytes
- 1 Gbps with 20 ms ⇒ 2500000 bytes
FAQ
Why divide by 8?
To convert bits to bytes.
What does the result represent?
It is the maximum data that can fill the network path at once.
Does higher latency increase BDP?
Yes, more latency allows more data in-flight.
How is this used?
It helps tune TCP window sizes for optimal throughput.
Is round-trip or one-way latency used?
Use round-trip latency (RTT) for accurate BDP calculations.
Additional Information
- BDP helps determine optimal TCP window sizes.
- Higher bandwidth or latency increases the amount of data in flight.
- Result assumes full utilization of the link.
