The following figure illustrates the DS field:

The DSCP value used to identify 64 levels (2

=64) of service determines the forwarding behavior that each packet gets

across the DiffServ network. Based on the marking rule different kinds of traffic can be marked for different priorities

of forwarding. Resources can then be allocated according to the DSCP values and the configured policies.

The following is an illustration about how the bits are used in DSCP field.
