Network Calculator

Calculate throughput, BDP, and transfer times from bandwidth and latency

Input Parameters

Bandwidth (Mbps)

One-way Latency (ms)

TCP Window Size (KB, optional)

Calculation Results

Round-Trip Time (RTT)

20 ms

RTT = 2 x one-way latency = 2 x 10 ms

Bandwidth-Delay Product (BDP)

244.14 KB

BDP = 100 Mbps x 20 ms = 2000000 bits

Optimal TCP Window Size

244.14 KB

= BDP (Bandwidth-Delay Product)

Effective Throughput

100.00 Mbps

Full bandwidth utilization

Transfer Time Estimates

These are theoretical values based on effective throughput. Protocol overhead, packet loss, etc. are not considered.
