How to use this tool

  1. Enter the labeled inputs in the indicated units.
  2. Calculate and compare every output against the stated model assumptions.

Try this example

{
  "payload": 1000,
  "overhead": 40,
  "rate": 10000000,
  "rtt": 0.02,
  "ack": 40
}

Accuracy and scope

One outstanding frame, equal forward/reverse rates, lossless link; RTT input excludes serialization. Simplified analytical model; not a design recommendation or safety certification.
