### Calculate Data and Line Rates for Fixed Packet Sizes

Source: https://ostinato.org/docs/faq

Use these formulas to determine throughput when using a fixed packet size in your streams.

```text
Data Rate (in Mbps) = (fps * packetSize * 8)/1000000
Line Rate (in Mbps) = (fps * (packetSize+20) * 8)/1000000
```
