Figure 2-14 Modify DiffServ Rule
Class Selector DiffServ Code Points (DSCP)
Some implementations of DiffServ will prioritize traffic by Class Selector
assignment. This is defined in the DiffServ Code Points (DSCP) within the IP
header. The first 3 bits of the DSCP define the Class Selector Precedence (or
Priority), as shown in table 2-1.
The modem/router will prioritize the traffic based upon the DSCP Class Selec-
tor Precedence.
Note: All traffic that does not have the DSCP Class Selector Precedence
defined (000 000) will be placed in the Default Queue and have a Prece-
dence of 9.
