Worked example

Inputs

Payload throughput
1000000000 bit/s
Assumed maximum segment lifetime
120 s

Expected results

32-bit sequence wrap interval
34.35973837 s
Bytes per lifetime
1.5e+10 bytes

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

{
  "rate": 1000000000,
  "lifetime": 120
}

Accuracy and scope

Constant TCP payload rate; sequence protection also uses timestamps and connection state. Simplified analytical model; not a design recommendation or safety certification.
