Briefly list the steps necessary to compute the total bandwidth for a VOIP call.
Posted by engineeringtop on January 22, 2008
- Determine the codec and the packetization period
- Determine link-specific information (cRTP, Layer 2 protocol, security protocol and tunneling?)
- Calculate packetization size (size of voice payload)
- Calculate the total frame size
- Calculate the packet rate (1/packetization period)
- Calculate the total bandwidth
Equation:
Total packet size = Total bandwidth
payload size nominal bandwidth
