How to use this tool

  1. Enter application payload, all frame and protocol overhead, preamble and gap equivalent, link rate in the displayed units.
  2. Calculate the scenario, then compare it with measurements before changing a system.

Try this example

{
  "payload": 1460,
  "headers": 58,
  "gap": 20,
  "rate": 1000
}
