Using WebSocket Message Traffic Planner
Estimate payload bandwidth for a fixed client and message rate.
- Enter clients, messages per client per second, payload size, active duration using the units printed under each field.
- Choose Calculate, or enable live updates. Review the result labels and formula assumptions.
- Save scenarios to compare up to five variations, then copy the report or download JSON or CSV.
Example
Clients: 500 clients Messages per client per second: 2 messages Payload size: 200 bytes Active duration: 8 hours Payload rate · MiB per second: 0.19073486 Total payload · GiB: 5.364418
Questions & answers
What does WebSocket Message Traffic Planner calculate?
Estimate payload bandwidth for a fixed client and message rate.
Which units should I enter?
Clients uses clients. Messages per client per second uses messages. Payload size uses bytes. Active duration uses hours. Convert values to these units before calculating.
Which formula does it use?
Traffic = clients × rate × payload bytes; transport framing and TLS overhead are excluded.
What does the included example show?
Clients: 500 clients; Messages per client per second: 2 messages; Payload size: 200 bytes; Active duration: 8 hours. Result: Payload rate · MiB per second = 0.19073486; Total payload · GiB = 5.364418.
Can I compare different settings?
Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.
Can I export the calculation?
Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
