sci.network-bandwidth-latency Calculator
Calculates network throughput, latency (RTT), and bandwidth-delay product BDP = bandwidth × RTT from link parameters. BDP for a 100 Gbps transoceanic link (150 ms RTT) = 1.875 GB — TCP window size must exceed BDP to saturate the link; standard 64 KB window fills only 0.003% of this link.
Inputs
File Size Mb
Reference formula or conversion factor shown for context.
Bandwidth Mbps
Horizontal extent perpendicular to the length.
Latency Ms
Reference formula or conversion factor shown for context.
Packet Loss Pct
Reference formula or conversion factor shown for context.
Results
transfer time (seconds)
The computed duration or time value.
TCP goodput estimate (Mbps)
The value at the specified point or condition.
RTT (ms)
Reference formula or conversion factor shown for context.
Mathis equation: B ≤ MSS/(RTT·√p)
The value at the specified point or condition.
transmission time
The computed duration or time value.
latency dominates when
Time from request initiation to response received. Composed of processing time, network round-trip, and queuing delay.
