Schedulers on the Router Hardware and PIC Families

Table 1 compares the PIC families with regard to scheduler statements or features. Note that this table reflects the ability to perform the scheduler function at the PIC level and not necessarily on the system as a whole. In this table, the OSE PICs refer to the 10-port 10-Gigabit OSE PICs.
