Sample Behavior Aggregate Classification
Table 1 shows the device forwarding classes (FCs) associated with each well-known Differentiated Services (DiffServ) code point (DSCP) and the resources assigned to the output queues for a sample DiffServ CoS implementation. This example assigns expedited forwarding to queue 1 and a subset of the assured FCs (afx) to queue 2, and distributes resources among all four forwarding classes. Other DiffServ-based implementations are possible.
