How to Use This Calculator
  1. Enter Total Distance, Number of Hops, and Processing Delay per Hop.
  2. Set Queuing Delay per Hop, Packet Size, and Link Speed.
  3. Review One-Way Latency (ms) and Round-Trip Time (RTT) (ms).
  4. Use Propagation Delay (ms) and Total Processing Delay (ms) to inform your decision.
  5. Use the chart to visualize the results and explore different scenarios by adjusting inputs.
