4.4.1 Example Parameters and Scenario
The following figure shows the network you want to set up in this example. The WAN port
has an upstream (outgoing) speed of 512 kbps. To prevent SIP-based VoIP (Voice over IP)
traffic from getting delayed due to heavy WWW or FTP traffic, you reserve 128 Kbps of
bandwidth for outgoing VoIP traffic (from LAN to WAN) and higher priority than FTP or
WWW traffic.

The following table shows the example information you configure in the bandwidth
management screens.
