FLQ scheduler. The QM is responsible for all the non-bandwidth func-
tions, which include managing up to 1 Million queuing structures,
handling cell and packet arrivals and departures from these queues, and
maintaining a database of congestion management and statistics
parameters for each flow queue (FLQ). The FLQ scheduler is respon-
sible for managing the FLQ bandwidth functions.
1M discrete flows. In addition to the scheduling levels provided by the
89TTM552, the 89TTM553 provides one or two levels of additional
scheduling hierarchy. It also provides guaranteed minimum rate,
maximum rate capping, excess rate distribution using weighted fair
queuing (WFQ), byte rate shaping, and dynamic configuration adjust-
ments.

tion and bandwidth management features are enabled at the flow level
as well as at the aggregate-flow level.
