Using Protocol Prioritization Queues

The Dequeuing Process

After queuing packets, the router empties the priority queues by sending the traffic

to the transmit queue using one of two dequeuing algorithms:

• Bandwidth Allocation Algorithm

• Strict Dequeuing Algorithm

By default, protocol prioritization uses the bandwidth allocation algorithm to send

traffic from the three priority queues to the transmit queue. You specify the active

dequeuing algorithm by setting the Prioritization Algorithm Type parameter, as

described in “Editing Protocol Prioritization Parameters” later in this chapter.

Figure 2-1

illustrates the dequeuing process, with default configuration values.
