Example: Configuring Qos For Voip - HP 7102dl - ProCurve Secure Router Configuration Manual

Example: Configuring QoS for VoIP

You should now be able to configure QoS for specific applications. You will
be guided through the process of configuring VoIP for the Frame Relay
network shown in Figure 8-9.

Figure 8-9. Example QoS Configuration
This organization uses general switched telephone network (GSTN) tele-
phones that follow the G.711 standard. VoIP calls must be carried from the
headquarters to each remote site. The organization anticipates that at the
busiest time of day the network should support up to 12 calls. You would
configure a low-latency queue to guarantee this bandwidth.
To deliver QoS for relatively small, time-sensitive VoIP frames, you must:
consider the special needs of your VoIP application
define VoIP traffic
determine the amount of bandwidth necessary for VoIP traffic
mark signaling traffic for special treatment
configure rate limiting and fragmentation if you are using Frame Relay
