Worked example

Inputs

Codec payload rate
64000 bit/s
Packetization interval
0.02 s
IP header bytes
20 bytes
Extra per-packet bytes
0 bytes

Expected results

Payload bytes per packet
160 bytes
Packets per second
50 packets/s
IP-layer bit rate
80000 bit/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

{
  "codec": 64000,
  "interval": 0.02,
  "ip": 20,
  "extra": 0
}

Accuracy and scope

Basic 12-byte RTP header; excludes silence suppression, aggregation and layer-2 overhead unless added. Simplified analytical model; not a design recommendation or safety certification.
