Bandwidth Delay Product Calculator

Bandwidth Delay Product Calculator calculator can be used to determine the maximum data that can be in transit in a network path between two endpoints, helping to understand potential congestion and buffer requirements.

Input Parameters

Calculation Results

Calculation Formula

BDP = Bandwidth × RTT

Where:
BDP (Bandwidth Delay Product) - Maximum data in transit (in bits)
Bandwidth - Network bandwidth in Mbps
RTT (Round-Trip Time) - Time for a packet to travel to destination and back in milliseconds

Calculation Result

Bandwidth Delay Product (BDP): 0 bits

Equivalent to: 0 GB

This is the maximum amount of data that can be in transit in the network path at any given time.

What is Bandwidth Delay Product (BDP)?

The Bandwidth Delay Product (BDP) is a fundamental networking concept that represents the maximum amount of data that can be in transit in a network path between two endpoints at any given time. It's calculated by multiplying the network bandwidth by the round-trip time (RTT).

How to Use This Calculator

  1. Enter your network bandwidth in Mbps (Megabits per second)
  2. Enter the round-trip time (RTT) in milliseconds
  3. Click the "Calculate" button to compute the BDP
  4. The result will be displayed in both bits and gigabytes

Practical Applications

Understanding BDP is crucial for:

  • Network planning and design
  • Buffer sizing for network devices
  • Path optimization
  • Understanding potential congestion points

Example Calculation

If you have a network connection with 1 Gbps (1000 Mbps) bandwidth and an RTT of 50 ms:

BDP = 1000 Mbps × 50 ms = 50,000,000 bits = 6.25 GB

This means that at any given time, up to 6.25 GB of data can be in transit on this path.

Interpreting Results

A higher BDP indicates that more data can be in transit before experiencing congestion. This is particularly important for long-distance connections where RTT is higher. For example, a 1 Gbps connection with a 200 ms RTT (common for transcontinental links) would have a BDP of 200 GB, requiring significant buffer space at network devices.
