DSCP Based QoS Menu
The DSCP Based QoS menu lets you classify and prioritize traffic using DSCP tags. DSCP
allows the Gateway to determine how traffic classes should be prioritized. Using the DSCP
Based QoS menu, you can use DSCP to provide different levels of service to conforming
and non-conforming traffic by appropriately selecting the DSCP values in this menu. The
Gateway uses the Hierarchical Token Bucket queuing algorithm, which divides the 64
possible DSCP code values into 8 queues.
Table 7 shows the actual queuing.
