Sample BA Classification
Table 100 shows the router forwarding
classes associated with each well-known DSCP code point and the resources
assigned to their output queues for a sample DiffServ CoS implementation.
This example assigns expedited forwarding to queue 1 and a subset of the assured
forwarding classes (af1x) to queue 2, and distributes
resources among all four forwarding classes.
Other DiffServ-based implementations are possible. For configuration
information, see Configuring Class of Service
with DiffServ.
