5-16 Network Design Considerations
Figure 5-4 Voice and Data Network Implementation shows how a voice and data
network can be implemented.
After the router is configured for QoS, it examines incoming packets and allocates a
priority to the packet. Figure 5-5 Priority Queuing on Voice and Data Networks
shows the affect priority queuing has on voice and data networks. The packets arrive
randomly. They are processed and output according to the QoS policy. The VoIP
traffic is output first.
