Worked example

Inputs

Packet bytes
1500 bytes
Each link rate
100000000 bit/s
Serial links
3
Total distance
200000 m
Propagation speed
200000000 m/s

Expected results

Total serialization
0.00036 s
Propagation delay
0.001 s
One-packet delay
0.00136 s

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

{
  "bytes": 1500,
  "rate": 100000000,
  "hops": 3,
  "distance": 200000,
  "speed": 200000000
}

Accuracy and scope

One packet, equal rates, store-and-forward hops; no queueing or processing delay. Simplified analytical model; not a design recommendation or safety certification.
