WAN configuration examplePriority queuingPriority queuing is designed to give all mission-critical programs higher priority than less criticaltraffic. Traffic is queued as high, normal, medium, or low. Using priority queuing, all high-prioritytraffic is serviced first, then normal, etc.The frame relay ingress queuing mechanism functions the same as on PPP interfaces. Theframe relay egress queuing mechanism also functions the same as on PPP interfaces, servingall PVCs configured on the interface, with an additional user-configurable DE buffer. The DEbuffer contains all traffic marked as Discard Eligible, and has the lowest priority.When using VoIP, the G350 enables a distinction within the high-priority queue betweenpriorities 6 and 7. The G350 uses priority 6 for the voice-bearer traffic, and priority 7 for thevoice-controller traffic. These two priorities are served on a round-robin basis. Within thehigh-priority queue, the priority 6 capacity is a maximum of 25% the size of the priority 7capacity to reduce the delay of voice flow. The priority 6-7 distinction exists in data mode aswell, where the queue is divided equally between both capacities.WAN configuration exampleThis section contains an example that illustrates a common PPP VoIP configuration betweentwo sites connected over a WAN.Issue 3 January 2005 105
